Method used

The biomimetic peristaltic robot, driven by a single drive motor, achieves orderly obstacle breaking and peristalsis through a combination of tracks and a screw rod. The rotation of the screw rod drives the wave-like motion of the connecting plate and the rotation of the drill bit to achieve peristaltic forward movement and sand removal.

Benefits of technology

It achieves a simple and reliable peristaltic motion, reduces the number of parts, lowers the failure rate, and reduces forward resistance and device size through trapezoidal surface design.
