World Peace Robot
Built by Greg Campbell, this
robot has been designed to fight in the Super
Heavyweight class of the BattleBots Bowl. The robot's main weapons are
the beak and lifting arm.
The World Peace robot is powered
by a modified chainsaw engine driving a hydraulic
pump at 2000 psi. Two hydraulic motors are used to drive the robot with separate left
and right proportional valves for steering and speed control.
The onboard controller (designed
with ExpressPCB) selects the best of two 9600 baud
RF links with instructions from the operator. Using this data, the board controls the vehicle and
arm by adjusting the engine throttle and the numerous hydraulic valves that feed the actuators.

This control box is used to
operate the robot remotely via the dual RF links. The right
joystick drives the robot while the left one operates the beak and lifting arm. The front
panel controls select between the robot's five operating modes.

Onboard the robot are 8 circuit boards: processor board, interface board, dual channel
receive board, I/O interface board, two hydraulic valve driver boards, status display board,
and the engine starter interface. Each made using the ExpressPCB layout program and
board manufacturing service. The processor board that controls the robot is based on the
National Semiconductor COP8 microcontroller.
