The project is initially a bug that can avoid the person’s hand.

The movement is based on this Arduino project:

https://create.arduino.cc/projecthub/Jerepondumie/ugly-bug-348dc7

Testing with 2 additional motors:

testing front legs

testing back legs

3D printing:

The ball joint was not used in the end as it did not print properly.

Testing the 3d printed legs

testing the fit of the legs

I didn’t manage to fit 4 motors in the cover so I removed one of the motors.

The fitting of the wires was a problem but in the end, coiling the wires helped a lot.

Final Test
