FAULHABER DC-Motors in Autonomous transport system

AMR on the advance

Transport solutions for materials are becoming increasingly customized and need to be as fully automated as possible. Mobile robot platforms – known in the industry as autonomous mobile robots (AMR) – are, therefore, on the advance in warehouse and production halls around the world. Focusing on this market is the Nuremberg- based startup Evocortex, which was founded in 2016 with the participation of experienced robot experts. The company is pursuing a completely new AMR concept in close collaboration with the neighboring Technical University of Nuremberg and other educational and research institutions.

FAULHABER DC-Motors in Autonomous transport system
"Conventional AMR often require spatial adaptations to the travel paths or even technical changes to the processes. For example, the vehicles need visual markings for orientation, and paths and intersections must meet specified dimensions and curve radii. We wanted to create transport robots that adapt to the needs of the customer and not the other way around." Managing Director Hubert Bauer

The "fingerprint" of the hall floor indicates the exact position

The autonomous mobile robots (AMR) from Evocortex require absolutely no preinstalled guidance system to determine their location and find the right way. They orient themselves simply using the irregularities in the hall floor. These exist even on seemingly smooth concrete floors and are registered by a high‑resolution camera that is mounted on the underside of the vehicle. The robot uses the images to obtain a "fingerprint" of the hall floor. Behind this ingenious system is the self-developed Localization Module (ELM) from Evocortex.

During the initial teach process, the robot moves across the hall floor in a grid pattern. With the help of complex algorithms, a highly precise map is produced from a pattern of individual points. In the future, this will also be performed using self-learning artificial intelligence. In addition, the controller detects the vehicle's own movement. By combining the data, it can – on a theoretical area of one square kilometer – position precisely to within a millimeter. To do this, just three identified points are needed. Even if 50% of the floor is covered with sawdust, the ELM remains unfazed and ensures robust, precise and exact navigation. Permanent new scratches in the floor are added to the map; features that disappear are removed after a certain time.

The AMRs can optionally be equipped with additional LIDAR sensors on one or two fronts. These scan the room in the direction of travel and detect obstacles – including those that are moving, such as people who cross the travel path. The vehicle stops immediately to ensure the safety of employees.

Unrestricted mobility with Mecanum wheels

A normal wheel moves in only the same direction as its axis. To precisely position a vehicle with such wheels, one must maneuver in the same way as when parking a car. To avoid this, the developers at Evocortex opted for the Mecanum wheel. Instead of a closed running surface, barrel-shaped rollers are mounted on its rim. They are fastened at an angle of 45 degrees to the axle of the wheel and can turn about their own angled bearing axis. The shape, size and spacing of the rollers are selected to give the wheel a continuous rolling surface.
When the Mecanum wheel turns, two force components arise: in the direction of rotation of the entire wheel as well as at a right angle to the wheel's direction of rotation. Thus, the resulting direction of movement lies in between: the Mecanum wheel "wants" to move at an angle of 45 degrees to the axial direction. Due to the mobility of the rollers, however, it has no directional stability. If there are additional forces, its own direction of movement can be deflected in any direction. On a vehicle with four Mecanum wheels, each of the 45 degree angles are arranged with a 90 degree offset. Thus, each wheel tries to move in a different direction. By varying the direction of rotation and speed of the individual wheels, the vehicle can be steered in any direction from a standstill or rotated on the spot. On the horizontal plane, it can thus move as freely as a hover car. The Mecanum wheels thereby enable agile and omnidirectional movement of the robot.

Scalability in millimeter increments

The AMRs from Evocortex offer yet another dimension of flexibility: they enable a practically unlimited selection of sizes. "If desired, we can adapt our robot to our customers' requirements in millimeter increments," emphasizes Hubert Bauer. "Every external dimension between 400 by 480 and 800 by 1200 millimeters can be realized." With the EvoRobot R&D and EvoRobot Industrial product lines, these also correspond approximately to the external dimensions of the load-bearing platform. All technology – sensor, controller, lifting unit and wheel drives – are housed beneath the platform.
The wheel drive module is a decisive element for this scalability. It is located directly above the wheel and, together with the wheel, forms a standardized, independent function unit. As a result, the wheels can be mounted at any distance from one another. The decisive prerequisite for this arrangement is a powerful motor with very small dimensions.
"We took a very close look to determine which motors on the market were candidates for this application," says Hubert Bauer, recalling the development phase. "Only with FAULHABER were we able to find the power density that we needed. The motors from the competition had no space left for the required torque."

Enormous power, minimal size

The wheel modules of the EvoRobot are equipped with DC-Micromotors of the 3257… CR or 3272…CR series. Each is fitted with an IEF3 encoder and a 38/2S gearhead. For fast stopping and to ensure the wheels remain locked in position once stopped, the wheel motors are also equipped with a brake. "Thanks to the enormous power of these micromotors, the EvoRobot can provisionally transport pallets with a load of up to 120 kilograms," explains Hubert Bauer. "This also functions on a ramp with a slope of up to five degrees and a speed of one meter per second." The EvoCarrier product line is designed for transporting small load carriers. In the inner workings of this AMR, things are even tighter. The ground clearance too is less than 100 mm here.
The developers therefore selected a so-called "flat rotor motor" here – a brushless motor of the 4221… BXT series measuring just 21 millimeters in length. In the long term, the managing director believes there will be a transition to brushless motors with the EvoRobot as well and the modules will be further standardized.
In the next step, Evocortex plans to couple the control of 2 or 4 EvoCarriers. They will then be able to together transport a euro pallet or even an entire shelving unit – yet another degree of freedom for the application. In addition to the ratio between power and volume, it is above all the zero maintenance and the reliability in continuous operation that play an important role in the operation of the AMRs. "Our requirements in terms of service life are more than satisfied by the FAULHABER motors," says Hubert Bauer. "In addition, it is of advantage that the drives function with all common industrial controls. The experts from FAULHABER were also very helpful in finding the optimum parameter settings for series production."
