The faceplate and cargo bay of the robot feature a regular hole pattern for attaching payloads and can be removed without tools for quick prototyping.

There are two cable passthroughs: one on the top edge of the cargo bay which is good for quick prototyping and one that penetrates the top cover and faceplate which is useful for keeping wires within the radius of the robot.

The bottom of the robot includes four cliff sensors to keep the robot on solid ground, a front caster (by default, the robot's center of gravity is forward of the center axis), charging contacts, two wheels with current sensors and encoders, and an optical odometry sensor.

Not visible is the robot's IMU, which is used with the optical odometry sensor and wheel encoders to generate a fused odometry estimate.
