Overview<\/h2>\n

The power distribution board (PDB) is designed to use a given 12V 10A supply from the Amiga platform and provide fused and protected 12V and 5V power supplies to the end effectors involved in our subsystems. These power supplies are used in conjunction with four Dynamixel Power Distribution Boards to establish power supplies for the Cutter, Gripper and Left\/Right Teleop arms. In addition to this, an emergency stop button is wired in series with the power supply to enable a total power shutdown in case of unsafe behavior.<\/p>\n

Each of the four powered device groups have different power requirements. Specifically, the Cutter draws a maximum of 5.2A@12V, the Gripper motors draw a maximum of 4A@12V, and each of the teleoperation arms consists of non-torque-enabled motors which draw 119mA@5V. The fused and protected 12V is used for the Cutter and Gripper motors, and a Pololu 1A@5V step-down voltage converter is used to supply the 5V needed for the teleoperation motors.<\/p>\n
