One Eyed Sumo was made out of Plastruct plastic from a local hobby store.
I attempted to make the base as low as possible
so that other robots could not get under it. A single servo motor holds
a GP2D02 IR ranging sensor. The servo motor swings the sensor from side to side.
This was used to search for the opponent. A BX24 microprocessor was used as the
brains of the sumo. Two CDS cells and two Red LEDs where used to detect the edge of the ring.
The robot took a weekend to build and several late nights to program.
For the April 19th 2003 competition
I made 1 hardware change and some software changes. I wired a pushbutton switch to one
of the I/O pins and used it as a start button. I made software changes to look for the opponent when power
is first applied. I usually placed One Eyed Sumo at 45 degrees off of the starting line.
When I press the start button One Eyed Sumo waits 5 seconds and goes straight for
6 inches and makes a 135 degree turn toward the opponent in an attempt to come in on the his side.
This worked very effectively against Mini Spatch.
