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.

Giant Magellan Telescope Multi-object Astronomical and Cosmological Spectrograph (GMACS) is a first-light moderate-dispersion imaging spectrograph under development at the Center for Astrophysics and Steiner Institute for the Giant Magellan Telescope. GMACS operates between 330 and 1050 nm with resolution 1000 < R < 5000 using a 0 . ″ 7 wide slit. The total slit length is 7′ with a field 6′ wide in the dispersion direction. GMACS carries 17 exchangeable aperture masks. Resolution > 10,000 is possible with the MANIFEST optical fiber front end that will initially address a 14′ diameter field. Standing 5 m tall with a mass of 11,000 kg, GMACS has two arms with 260 mm collimated beams split with a dichroic at 630 nm.
