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 to potential problems and to avoid disastrous situations, the joystick mode was also implemented. Therefore, when the button “Z” is pressed on the joystick device, the mode will change depending on the user’s preference.
After being able to successfully control the exoskeleton arm brace with EMG signals, a strength test was performed in the automated mode. The different strength tests are shown below.
Automated (EMG) Strength Test (0-3.63Kg) with Exoskeleton Arm Brace
Automated (EMG) Strength Test (2.23Kg) with Exoskeleton Arm Brace
Automated (EMG) Strength Test (3.63Kg) with Exoskeleton Arm Brace
The results showed that the arm was able to withstand the arm’s weight, with an additional 3.63Kg. The potential problems that could arise from wearing this device, is that when the arm is going down, a small amount of resistance is necessary for the device to understand the correct direction.
