Mechanics
The robot uses a very simple principle for locomotion inspired by the 20-year-old book "Insectronics" by Karl Williams. The first servo moves the right front and back legs forward or backward; the second servo does so on the left side (Fig. 1.1). The third servo moves the middle legs up and down.

To walk forward, the third servo first tilts the robot to one side so that only the front and back legs on the other side touch the ground. If these legs now swing backward, the robot moves forward at an angle. At the same time, the front and rear legs hanging in the air rotate forward. Then the robot tilts to the other side, and the legs now on the ground move back - creating a somewhat waddling forward motion.
To turn on the spot, you only have to modify this sequence slightly; to crawl backwards, you simply reverse the direction of movement of the legs.
