Droid Bot JR is a robot build using only parts from 31313 LEGO® MINDSTORMS® EV3 Set. This build is slightly smaller than Droid Bot 2.0, but still has many similar features. An optional handle allows for easy carrying in classrooms. It has been designed to allow the builder to easily replace the infrared sensor with the ultrasonic, use a rechargeable battery, and add a gyro sensor if needed.

This new NXT robot design is compact and very sturdy - ideal for classroom usage. It has been designed for use in our lessons and also works well on our Training Mats. We name it Cyberbot because of its distinctive handle which makes it look like a Cyberman from Dr. Who. The robot features a shielded color sensor as well as modular/easy to add sensors and a third motor.

This LEGO MINDTORMS EV3 Sumo Bot uses three EV3 Large Motors, two of which have “triple torque” due to gearing. In the false-colored picture, the pink 12-tooth gear that is directly connected to the EV3 Large Motor touches the turquoise 36-tooth gear. This “gearing down” increases its torque three times, for increased pushing power. The center motor operates the yellow “flipper” arms for upending opposing robots in a Lego Sumo or Battlebot competition. Parts from the EV3 45544 Education Set are supplemented by the third motor and EV3 Color Sensor (for detecting the edge of a Lego Sumo arena). You can use your spare parts to make the flipper larger; with it in the “up” position, it measures ~7”x7” (~22x22 studs). The EV3 Ultrasonic Sensor detects the opposing robot, or it can be replaced by a Mindsensors “Sumo Eyes” sensor for SuGObot competitions.

This Sumo Bot can be built using the LEGO Mindstorms EV3 31313 retail set’s parts. It features a front flipper, wide rubber tires for good traction, and the EV3 Infrared Sensor for manual operation via the EV3 Remote Control. Download the “Custom Remote” .ev3 project file for Remote Control operation. The EV3 Color Sensor allows for the robot to back up when “seeing” the perimeter line around the Lego Sumo ring. As an option, the pair of red 2L Technic Axles allow for mounting the Mindsensors “Sumo Eyes” to run the SuGObot program.
