Video of the PCB for the robot build. Not required but it does make things nice and tidy.

I tried PCBWAY for 3d printed clear resin parts as well. Turned out great.

The robot can walk forward, backward, flip end over end and turn.

I have built this programable robot using standard 180-degree servos and 270-degree digital servos. Both will work, but the 270-degree ones are best for performance.
The servos come in plastic gear and metal gear versions. If you use the plastic gear version the splined output shaft will be plastic, and the servo horn lever is held on with a self-tapping screw that will be to short once you add the 3d
