Reflective markers are attached to blue 3D-printed apparatus above and below the user's knee as well as two metal plates on the exoskeleton leg.
Key facts
- The OTS uses special cameras that emit light and capture what is reflected back by spherical markers arranged on objects of interest
- In the new study, the NIST researchers aimed to capture the motion of the knee, one of the body’s relatively simple joints, Bostelman said
- Reflective markers are attached to blue 3D-printed apparatus above and below the user's knee as well as two metal plates on the exoskeleton leg
- Researchers track and compare the movement of the markers to gain insight into how well the exoskeletons fit
Summary
A shoddily tailored suit or a shrunken T-shirt may not be the most stylish, but wearing them is unlikely to hurt more than your reputation. Exoskeletons, many of which are powered by springs or motors, can cause pain or injury if their joints are not aligned with the user’s. In a new report, the researchers describe an optical tracking system (OTS) not unlike the motion capture techniques used by filmmakers to bring computer-generated characters to life. The OTS uses special cameras that emit light and capture what is reflected back by spherical markers arranged on objects of interest.
