Build Your Own Autonomous Robot (LS-PL-634)

It’s time for another recipe, this time an autonomous robot of the Minisumo category, whose task will be to fight another robot in a round ring, called dohyo. Most of you have probably heard about the robot competitions that are organized from time to time. Perhaps you have also seen the struggle in various competitions with your own eyes. The included LS is not an electronics course but only some orientation towards robotics. There are many pages, many possibilities. You can buy a ready-made “KIT” for self-assembly and software or go to a higher level and build an autonomous robot fighting from scratch … We are then limited only by our imagination and starting requirements!

Minisumo Robot Criteria

A minisumo robot must meet the following criteria:
• it must be autonomous,
• the robot cannot be attached to the ground,
• the robot cannot emit large amounts of heat,
• after the signal to fight, it must wait at least 5 seconds without moving, or have a suitable starting module that allows the robot to be remotely started, depending on the competition,
• the robot must not contain devices that interfere with the enemy’s control system, flashing lights or devices that prevent movement,
• it is forbidden to install parts that may damage the surface on which it moves, or devices emitting gases, liquids or loose materials,
• the minisumo robot must fit in a 10 × 10 cm box, the height is not limited,
• the weight must not exceed 0.5 kg.

The place of the duel

The surface of the dohyo has the shape of a circle outlined with a 25 mm wide white ring, its outer diameter is 770 mm. The surface of the ring is black, made of a hard material with a low coefficient of friction. On the surface of the ring there are two parallel brown starting lines, 100 mm long and 10 mm wide. The starting lines are located 50 mm from the center of the ring (100 mm apart).


Robotics is one of the youngest sciences that combines elements of mechanics, automation, electronics, sensors, cybernetics and computer science. It sounds complicated, it can be dizzy, but it’s pure fun for us. We conduct our robotics workshops in an engaging and interesting way for participants. We combine elements of fun with learning and, as a result, students absorb information faster, having a lot of fun from it.
