CAD drawing for the laser-cut sumo robot.
6.d. Laser Cutting Example: Servo-Driven Sumo Robot
This custom sumo robot chassis is propelled by two radio-control hobby servos modified for continuous rotation.
The five laser-cut components consist of top and bottom panels, two identical side panels that hold the servos, and a
front shovel panel (see drawing below). The top, bottom, and side panels are attached by bolts and standoffs, and the
interlocking front panel is held in place with nylon cable ties. All the pieces were cut from 1/8" acrylic, and the top
and bottom panels are about 3.25" x 2.25".
This particular design was initially built with a BEAM circuit controlling the servos, but you could also control such
a robot with a
microcontroller-based robot controller [http://www.pololu.com/category/8/robot-controllers] .
If you want to design a similar robot, you can use our laser cutting service to build your own custom sumo robot for
less cost than most pre-made kits. For a tougher version of the robot that can take more abuse, you could also have
us cut the components out of ABS. The cutting cost would be about 60% more, and you wouldn’t have as many color
choices, but your robot would be almost indestructible!
