Komodo the Walking Robot

By Martin Majkut and Omar Sanchez

The goal of this project was to change rotational motion into locomotion without the use of wheels. To do this, we first spent a minutes researching examples of non-rotational locomotion. After looking at some really cool robots, we found the following example converting rotational motion into reciprocating motion:

We made an initial design using this method (of which we forgot to take pictures of). Our design was very unstable and would constantly fall over. So, we made improvements to the design by lowering the center of gravity both through motor orientation, placement and shortening the lengths of the legs. By keeping the EV3 and motors in line, we could have the center of mass as close to the ground as possible. The orientation of the motors is also key because it allowed us to use beams that are longer than the shortest beams in the kit, thus giving us a little bit more travel of the legs to move the robot forwards or backwards. Once the motors were connected, it was all about making the design as stable as possible. We added beams so the construction would not fall apart, added gears and tracks to increase stability while walking, and finally added the rubber beams (?) to allow Komodo the traction it required to move.
