The
Warhummer: Design of a Sumo Wrestling Robot |
This
paper describes the design of an autonomous sumo wrestling robot, the Warhummer.
The robot is controlled by a Basic Stamp II microcontroller. The main sensors
include ultrasonic transducers for locating and trackhrg i~n opponent, optical
sensors for detecting the rink perimeter, and mechanical sensors for detecting
contact with the opponent. The robot is mounted on four wheels and is capable
of rotating on the spot. Using state machine logic, the robot is capable of locating,
and advancing towards the opponent while continuously adjusting its course
in order to intercept the opponent. Once contact iis made, the Warhummer will
attempt to push the opponent out of the rink. This robot was designed to compete
in the 1996 Western Canadian Robot Games, two front corners of the vehicle. Both
transmitters are driven by a single 40 kHz oscillator based on a CMOS 555 timer
IC, Every millisecond the Stamp commands the oscillator to send a tone for 50
milliseconds (a ping). Each receiver is focused to receiwe the reflected tone
from their respective transmitters at either corner of the Warhummer. The receiver
is connected to a CA5 160 CMOS operational amplifier used as a signal booster
with a gain of 100. The output of the amplifier is coupled to an LM567 tone decoder
used to detect the 40kHz tone from the op-amp. The 567 IC has an active low output.
