This study presents the design and construction of a controlled device to measure the torque of industrial exoskeletons, with the results of static and dynamic testing on an exoskeleton model. A step motor in the test bench moves the exoskeleton arm in a predefined path at a prescribed speed, while a beam load cell measures the force to derive the torque. The proposed test bench can be easily modified for testing different exoskeleton models under the same conditions.
Exoskeletons have been introduced in industrial environments to prevent overload or repetitive stress injuries in workers. However, due to the lack of public detailed information about most of the commercial exoskeletons, it is necessary to further assess their load capacity and evolution over time, as their performance may change with use. We present the design and construction of a controlled device to measure the torque of industrial exoskeletons, along with the results of static and dynamic testing of an exoskeleton model. A step motor in the test bench moves the exoskeleton arm in a pre-defined path at a prescribed speed. The force measured with a beam load cell located at the interface between the exoskeleton arm and the test bench is used to derive the torque. The proposed test bench can be easily modified to allow different exoskeleton models to be tested under the same conditions.
