The Pololu Round Robot Chassis
The Pololu Round Robot Chassis is a small, low-cost mobile platform
for experimenting with robotics. With this kit, you can assemble a
differential-drive robot with independent gearboxes for the right and left
wheels, allowing for very precise motion control. Because the chassis is
perfectly round and the wheels are on a diameter of the circular robot, it
can turn in place without getting stuck.
The chassis plate has many holes for mounting sensors and electronics,
and the acrylic can readily be modified to meet your needs. The chassis
is very low to the ground, allowing you to add plenty of electronics and
sensors to the robot without worrying about it tipping over.
Note: This kit requires the Tamiya twin-motor gearbox (70097), ball
caster (70144), and truck tires (70101) kits that are packaged separately.
You will also need your own electronics circuitry to build a complete
robot.
