The design, construction, and explaination of the failsafe power supply will be detailed here.
This part allows for the robot to turn itself off, which can be instructed to do so remotely, or if the robot senses that a part has malfunctioned, or if battery voltage is below a critical level. It will also allow the use of two momentary switches to be used to turn the robot on and off.
This part is made on a perfboard due to it's simplicity.
