Exoskeleton Arm Brace controlled by Automated (EMG) Mode and Joystick Mode In automated mode, the user’s bicep and tricep muscles control the direction of the exoskeleton arm brace. The benefit of this, is that the user will not have to rely on the joystick device to tell which direction the arm is moving. However, due …

PCB Design
The PCB design was done through KiCAD, with the 3D simulated image shown below. The actual PCB that came from PCB milling machine (front and back images) are shown below. After the PCB came out, rubbing alcohol was used to remove any excess residue. We have already begun to solder the components onto the board …

Exoskeleton Arm controlled by sEMG signals and Joystick Device
In the video above, through 3D printed parts, we were able to construct an exoskeleton prototype that was successfully able to move through the sEMG signals located on the bicep and tricep. The servo used to control the prototype exoskeleton is shown in this link. The actual sEMG signals from the video are shown in …
