Mini Hexapod |
This is an autonomous robot that will go forward until it runs into
something. There are only two sensors on this walking robot, the
left and right whiskers. Depending on which whisker is hit, it will
back up a few steps then turn in the opposite direction of the hit
whisker then start going forward again.
The body is made out of plastic, and it is 4.5 inches wide, 4.7 inches long (not including the whiskers), 3.0 inches tall (4 if you count the wires), and weighs 4.7 ounces (133 grams). Power is supplied from 4 AAA batteries, the microcontroller is a Microchip PIC 15C58A, and propulsion is three sub-miniture R/C servo motors |

Pete's Folly |
This robot was built to compete in the mini sumo class of the Robot Sumo Wrestling competition. The robot sumo competition is where two autonomous robots try to push one another out of a ring. The specifications of the mini sumo class is that the robot must fit inside a 10 cm X 10 cm box (3.94 in. X 3.94 in.), and not weigh more that 500 grams (17.6 ounces).
The body is made out of aluminum, and is 3.9 inches wide,
3.0 inches long, and weighs 386 grams.
The servo motors are powered by 4 AAA batteries, the microcontroller
is powered by a 9V battery.
The microcontroller is a Basic Stamp 2 from Parallax Inc, and
propulsion is through three sub-miniture R/C servo motors
It uses two IR reflective sensors on the front two feet for detecting
the boundary edge of the sumo ring, and two IR LEDS and a IR reveiver
module for detecting its opponent in the ring. The photographs shown here are the aluminum frame with only the servo motors attached, and with the electronics and batteries attached. |
