Don't mind the beams

There is a difference between the beams we used and the ones that are in the instruction. This comes to show that sometimes you can vary with the parts, as long as you keep the general idea of the construction.

LEGO Mindstorms Castor Bot building instruction

Building instructions for a LEGO Mindstorms EV3 Robot that we call CastorBot, because it uses the castor ball. 


In this section of the course your goal is to build the Castor Bot. This is the robot. It has a brick, two motors, two wheels and it has the ball wheel at the back. Your goal is to follow the PDF instructions and build the robot. While you are following the instructions you'll see that these two beams here will be different. Currently we didn't have the 13-beam so we added 15 hole beams but this should not be a difference for the behavior of the robot. Follow the instructions and build the Castor Bot. Of course, at the end don't forget to take a picture of your robot, a short video and share this picture or video with us.
