The project is initially a bug that can avoid the person’s hand.
The movement is based on this Arduino project:
Testing with 2 additional motors:
testing front legs
testing back legs
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.
