1 × micro:bit XGO Robot Kit

1 × Smart Phone

11.3. Hardware Connection

11.4. Control

There are four ways to control the XGO which include the performance mode, the overall mode, the single-leg control and the servo control.

The performance mode has all the preset commands which could control xgo with a low DOFs and a high operability.

The overall mode is able to control the speed and directions with a high DOFs and senstive operation.

Single-leg control and servo control can be controlled with a much smaller granularity for a single leg (left front leg, right front leg, right rear leg, left rear leg), and adjustment of the upper and lower rudder for a single leg. Commonly used for minor adjustments to specific movements.
