1. The problem

    A walkable robot that can overcome obstacles

  2. The idea

    Build a remote-controlled crawler robot based on EV3.

  3. The prototype

    Thanks to a mechanism, the claw can lift and grab using a single motor. The large motors drive the tracks. The track's shape allows it to overcome large obstacles, but the pads on them require replacing with pieces of regular rubber from a tire. A "tail" is added at the rear to ensure stability when overcoming obstacles. Since Lego pieces can fly apart on impact, zip ties and blue electrical tape are used to securely connect the pieces.

  4. The result

    A ready-made remote-controlled robot

What we learned

Grapple designs, tracked movement, control application
