LEGO MINDSTORMS Robot Inventor
This walker is modelled after the AT-ST Walker from Star Wars. It walks on its two legs, the cab can rotate left and right, and it can shoot the two projectile darts from your Robot Inventor kit.
You can control it with the remote control program, or try modifying the autonomous program to make your own autonomous action sequences.
Make sure you center the turntable using the knob on the motor so that the cab is facing straight forward before running any of the programs. Because of the range of motion in the geared turntable, the motor is not able to reliably center itself.
