Motion Control Application – Maxon Drives Power – Hull Cleaning Robot for Large Ships!

Motion Control Application – Specially designed robotic crawler navigates around the underwater portion of a ship to remove the biofilm layers that accumulate there. As a battery operated, autonomous vehicle, component selection made up a highly critical part of the design and manufacture.

underwater portion of ships. © 2011 SeaRobotics

Fall River, MA — Motion Control Components Application – Toxic paint is used on the bottoms of large ships to prevent fouling, which is when a biofilm layer develops, decreasing the ship’s efficiency in moving through the water. The toxic paint continually leeches copper and other heavy metals into the underwater environment as well, causing damage to the organisms that live there. To further complicate the matter, the paint must be blasted off and replaced every 5 to 10 years, at which time literally tons of toxic waste is produced and needs to be disposed of. A ship that operates with a clean underwater surface free from fouling—even thin biofilm layers—will operate so much more efficiently that potential savings can easily reach over five percent in fuel costs alone. Without the concern for fouling, a ship’s underwater coating can be engineered for corrosion protection and longevity rather than its need to eliminate the potential for biofouling. If realized on all the ships operating in the world today the energy savings would greatly reduce the presence of greenhouse gases, as well.

To eliminate the requirement for toxic paint and its cleaning waste, there needed to be a method to “groom” the biofilm from the underwater portion of a ship. The idea was to create important changes for the ships being built as well as for the environment. That is where the HullBUG (Hull Bioinspired Underwater Grooming) concept originated. “The most important feature of the HullBUG is its small size,” according to SeaRobotics Research Engineer, Dr. Kenneth Holappa. “It is only about half a meter in length. This was a necessary design feature, needed to allow the vehicle to maneuver over the curved surface of the hull while continually maintaining close contact with the surface.

This close-up of the HullBUG clearly shows its sensor alignment
system that helps it keep on course while cleaning a hull.

Because there are hazards associated with operating such a device underwater and in a harbor environment occasionally a HullBUG might be lost or destroyed during operation. Keeping the size and cost of the system low definitely helped to eliminate damage as a major obstacle to implementation. So, from the very beginning of the project, small size and low cost have been identified as being critical to the satisfactory implementation of the HullBUG project. As can be expected, this need to maintain a particular size and weight filtered into the selection of every component of the design.

Motion Control Components

The selection of the motors to drive the HullBUG involved a number of critical engineering constraints and compromises. SeaRobotics decided to make two basic models, one with wheels and one with tracks, and offer several options for keeping track of the system’s progress, which will be discussed later. Sizing of the motors, for example, required a calculated estimate of the power, speed, and torque characteristics of the manufactured devices. Determining factors included the resistance caused from pushing the grooming tool across the surface of the ship, the hydrodynamic resistance of the vehicle itself as it moved through the water, friction losses in the shaft seals that were used to protect the motors from the saltwater, and track or wheel friction dependent on which version of the unit was used.

In this close-up you can see the max-on EC45 brushless motor and
interface boards about to be safely mounted inside the machine.

maxon motors offers a full line of fractional horsepower moving coil DC motors and brushless motors ranging in size from 6mm to 90mm, and from 30 mW to 500 watts. They also offer gearheads, controllers, and accessories. “The breadth of their product line and quality of their service helped us to feel comfortable that we had selected the right partner,” Ken said. Flat motors manufactured by maxon Precision Motor provide long life along with their low profile package. The entire EC series of brushless motors are electronically commutated, which enables them to have extremely long motor life since there are no mechanical brushes to wear out. The motors incorporate ball bearings or ruby bearings that also add to the longevity of the motors, especially needed in such harsh conditions. The flat motors were designed specifically for robotics applications where size and weight are important selection criteria. The EC45 flat motors selected for the HullBUG are very efficient and weigh only 75 grams. Continuous output power is 30 watts, while the maximum speed is 10,000 rpm (much faster than what was needed for this application). The important specification for this application was torque. Even under the potentially harsh environments that the HullBUG would be engaged in, the EC45 offered a maximum continuous torque up to 56.2 mNm depending on the winding chosen by the user. The Maxon brushless motors are built to IP54 standards, which was important to the application. Furthermore, the motors were also available in the system voltage that SeaRobotics required for the HullBUG application.

According to Ken, “The large load capacity of the shafts of the GP42 gearhead allowed the wheels to directly mount to the gearhead shaft, greatly reducing the complexity of the overall design of the system.” Gearheads manufactured by maxon are available in a wide range of ratios to enhance speed reduction and/or torque multiplication dependent on the needs of the user’s application. Concentric input and output helped to facilitate simpler and more direct mounting arrangements, as well.

Given that the HullBUG vehicle was to be completely autonomous, it had to be designed in such a way as to operate for many hours on batteries (cables would simply get in the way of the grooming operation). In order to maximize battery life, the grooming of the biofilm had to be performed in the most efficient manner possible. Navigating in a random pattern may eventually get the job done, for instance, but not in a reasonable amount of time. Plus, a typical ship presents a very large underwater surface, often as upwards of three thousand square meters. To keep this amount of area groomed it is expected that a user would employ multiple HullBUG vehicles to operate at the same time and, consequently, require a method of acquiring sophisticated coordinated navigation.

Navigating the HallBUG

A toolset of navigation modes has been created to allow multiple HullBUGs to efficiently groom a ship by dividing the ship’s underwater surface into regions. Numerous algorithms have been incorporated to accurately groom the ship in steps down to the turn of the bilge. Additional algorithms and associated sensors are used to allow efficient grooming of the flat bottom of the ship. Miniature acoustic ranging sonar (MARS) is also an option for navigation control of the HullBUG. This is where a very small close range, pencil beam sonar was specifically developed to allow the vehicle to “see” an upcoming wall or cliff condition such as bilge keels and bow thrusters. Yet another mode of navigation uses a MEMS rate sensor for navigation information. Another feedback mode uses encoder based odometry. Hall sensor feedback from the motor is used as an encoder signal to establish an accurate estimate of odometry. Hall sensors were used instead of optical encoders because of size and cost. The Hall sensors provide better than 1mm accuracy in the measurement of odometry with the motor/gearhead combination chosen.

Ongoing Software Development

An autonomous vehicle is often software heavy in terms of engineering efforts once you’ve selected and implemented the proper motion control system. Getting smooth reliable navigation maneuvers that result in accurate positioning in a widely varying environment was one of the more difficult challenges for the design team. Multiple layers of software were necessary for handling the number and variety of possible events that can occur during grooming. And, the proper organization of the control logic to allow extensibility of navigation behavior was the most difficult part of this complex system. “Software development will continue to be an ongoing effort even after the years already put into it,” Ken said. “Though the vehicle is completely operational, there remains a considerable amount of on-ship testing to be done.” As the project moves forward and into the field, there will no doubt be additional issues that will crop up and need to be addressed, as well. Even now, the vehicle must be able to reliably accomplish its task in a hostile environment and in an unmapped terrain. Then it has to be able to return to the waterline of the ship for retrieval.

This operation must be done repeatedly for days, months, and years, and with multiple systems in the water at the same time. Although this sounds as though it is overly difficult, according to Ken, “A technician was recently trained to use the vehicle and was fully competent within a short period of time. The user interface was borrowed from SeaRobotics’ Unmanned Surface Vehicle (USV) product line and presented an intuitive graphics-driven interface that has hundreds of hours of use by many different customers.” The vehicle is operational and the navigation software is working. The next primary focus will be the structuring of the interface to improve ease of use and allow non-engineering personnel to manage operations.

motion control speed reducer

 

RMI Drives-Logo

North Babylon, NY – Rolling Motion Industries (RMI) has released for production the next two in it’s series of highly efficient speed reducers. These 3-to-1 speed reducers use “game changing” traction drive technology. The MAR-17-1-3.1 and the MAR-23-1-3.1 Speed Reducers feature 98% efficiency and with only 6 moving parts they typically out last conventional gearboxes and speed reducers by a factor of 3. The MAR17-1-3.1 Speed Reducer is designed for input speeds up to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-1-3.1 Speed Reducer is also rated for speeds to 3600 rpm but with an input of 20 to 30 in/lbs of torque. As the output speed is reduced by a factor of 3 the output torque increases by a factor of 3.

Using an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12 that cools and lubricates the traction drive these high efficiency speed reducers generate up to 72% less heat even after days of continuous operation. There is no slippage or lost motion between the input and output shafts even though there is no metal to metal contact as the traction fluid is continuously changing from liquid-to-solid-to-liquid as the driving and driven elements interface in the drive. Creating 38% lower dB at 3000 rpm than conventional gearboxes these people friendly speed reducers are ideal for use in medical equipment such as mobile hospital equipment and dialysis machines as well as pumps, blowers, fans, turbo and super chargers, conveyers, HVAC systems, and other power transmission and motion applications.

Having low vibration, and no torque losses from 10 to 3000 rpm, these speed reducers featuring traction drive technology lets a motor operate at peak efficiency while having a damping effect on a motor’s torque ripple. These revolutionary speed reducers are available with an optional overriding clutch. Incorporating standard NEMA mounting dimensions, these speed reducers can be easily integrated into new and existing applications.

About Rolling Motion Industries (RMI)-

About Rolling Motion Industries (RMI): In 1993 John Pawloski and his brother Ray took over the family business, Jewelers Machinist Co. They realized they needed to switch from outdated conventional thread grinders to CNC thread grinders. As a result, Jewelers Machinist Co is recognized as the source of some of the most complex thread grinding in the industry. The concept for the RMI traction drive came from John in 2007. Working in that high precision industry aided John in the development of the RMI Traction Drive.

In the years that followed, the design of the individual components and formula of the engineered traction fluid were finalized, testing was completed, a patent granted, and production begun. The RMI Traction Drive is one of the most efficient ways to transmit power from one point to another. Utilizing rolling motion, RMI is able to transfer power at various ratios with minimal energy loss. Tested against V-belt, direct drive, chain, and gearbox setups, RMI Traction Drives offer energy saving benefits through true efficiency rating percentages up to 98%. The high efficiency of the traction drive allows electric motors to run at their peak efficiency ranges.

There are many applications where it can be used from automotive to industrial to medical. The RMI traction drive can be used in the electric vehicle market and precision applications. Offering benefits such as low backlash and no back driving, it set a new standard for “high efficiency”.

Motion Control Application – Implantable medication delivery systems: Where every microliter counts!

Motion Control Application –

Implantable medication delivery systems can have a decisive influence on the quality of life of the patients. In many cases, such delivery systems are vital for the survival of the patients – the systems have to be absolutely reliable. maxon motor manufactures high-precision micro drives for medication delivery systems.

Maxon Logo

motion control application - implantable pump

Fall River, MA — Motion Control Components Application – Patients that suffer from chronic pain, metabolic disorders, diseases of the central nervous system and tumor diseases require accurately dosed medication. Here implantable medication delivery systems are used. Through the localized medication delivery, the dosage can be reduced to the required minimum. These infusion systems thus improve the quality of life of the patients. For many patients, it is only the medication delivery system that allows them to have a life outside of the clinic. Repetitive invasive, painful operations can be avoided. The risk of medication dependency and undesired side effects are reduced to a minimum. All these factors can contribute to the disease no longer being the central focus of the patient’s life.

For example, an active implant is implanted in the lower abdomen directly underneath the skin, where it delivers the medication dosage, programmed by the physician, to the body at the defined times of the day. The implantable unit has a wireless data interface to a patient interface by which the dosage can be adapted at any time. At regular intervals, the internal medication reservoir can be refilled by a specialist. The life span of the active implants measures many years and is limited only by the life of the battery. The core of the active implant is a piston pump manufactured by maxon medical, which specializes in medical technology and is a division of the maxon motor Group. However, the micro drives for implantable medication delivery systems are not comparable with customary maxon motors. In a customary motor, rotary motion is generated and yields torque and speed of rotation.

maxon miniature piston pump

The reciprocating piston pump generates a linear movement that results in liquid pumping. The individual parts of the pump have very narrow tolerances and allow the pump volume to be adjusted with a precision of less a microliter per piston stroke.

As active implants are in direct contact with human tissue, biocompatible materials are an absolute requirement. Therefore, in most cases, titanium is used for the implants. Machining of titanium, especially safe and reliable laser welding, requires a very high level of expertise. Special testing and quality methods, such as inspecting the penetration depth, microhardness and density of the weld seams, are established procedures at maxon medical. The customer requirements on the product are thus fulfilled and the reliability and constant quality of the manufacturing processes are guaranteed. The entire assembly of the implantable micro drive takes place under cleanroom conditions.

maxon medical – Specialist for medical drive solutions and active implants

maxon medical specializes in the manufacturing of medical drive solutions for active implants. The division received ISO 13485 certification in December 2008. The quality management system and the project organization ensure safe, reliable and standard-compliant products and provide the customer with a sound basis for statutory approval of the final products.

Professional project organization and a proven risk management system allow efficient implementation of customer projects. Strict maintenance of statutory requirements has top priority in the implementation of medical technology projects with risk class IIb + III.

Santa Clarita, CA —–

When three-phase AC power is applied to the primary, a travelling electromagnetic flux wave is induced and moves relative to the primary. The wave induces an electric current in the conductive reaction plate. The induced electric current interacts with the magnetic flux to produce a linear force. The speed of the motor can be varied by changing the input frequency using an adjustable frequency drive.

Each coil pair operates as its own voice coil.

Redundancy is a requirement on many flight systems in a special case when one coil faults, the other can be used to make the motor “fault-resistant”.

Other systems require simplified circuitry which would not allow the change of current polarity in order to change the direction, in these cases each coil can be used to drive the coil in a single direction. The challenge in manufacturing a redundant coil is ensuring the same performance no matter the coil, which requires precise manipulation of the magnetic circuit design, and the precise coil layout to ensure the identical operation and constants for each coil. This will allow the controls to seamlessly switch between the two coils.

There are two ways of accomplishing this coil redundancy. The most common way would be to generate multiple coils operating on individual magnetic circuits. This requires a longer coil and multiple magnetic circuits; however this is the most robust design and the least vulnerable to damage or interference from the redundant coil. The NCC08-18-025-2R2C is an example of the multiple coil design. An alternate method, which allows for the most compact solution, would be a multi-filar wind. This method only requires one magnetic circuit, which is why the length is shorter. In this case multiple coils are wound in the same winding space.

Linear Motion Control

 

LM76

E. Longmeadow, MA Motion — Control Components – Linear Motion – LM76 now offers one piece ETX Linear Bearing/Pillow Blocks that will not degrade in a radioactive environment! Machined from a solid block of self lubricating ETX, linear bearing-blocks have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures As there is no other materials such as PTFE seals or lubricants these bearing-blocks are maintenance free. Custom designed for use in a nuclear power plant these linear bearing/pillow blocks travel on ceramic coated shafting (also supplied by LM76) completely submerged in radioactive water. Designed with a slight interference fit between bearing ID and shaft, contaminates are scraped from the shaft’s surface. The low frictional characteristics of ETX have little impact on drive force. They are now available in Inch and Metric sizes.

ETX bearing-blocks are also FDA/USDA/3-A Dairy compliant and are also are ideal for: Pharmaceutical, medical, food, and dairy processing applications.

EXT features a high continuous service temperatures up to 210°F (100°C) and offers good chemical and abrasion resistance, low moisture absorption, and resistance to staining. These ETX linear bearing-blocks with the slight interference fit keeps the bearing free from debris and bacterial contamination, are not affected by biological fluids, mild acids, can be washed down with cleaning agents, and steam cleaned.

Don’t need solid EXT bearing-blocks consider the FDA/USDA/3-A Dairy compliant electroless nickel coated or stainless steel pillow blocks with PTFE linear bearings and Snap-in EXT Scraper Seals which are available for closed linear bearings, and closed pillow and flange blocks.
