Here.Īfter you put it, place back the back wheel on the back frame and press the red pin so that it will lock the back wheel. You have to put it into the middle hole of the back frame. Then you have the back wheel which, as you see, has this flexible pin which is turning. First, I'll attach the first motor and then the second one. Then, you have the back frame that should go into the three holes at the back of the motor. You attach the two motors onto the frame.
Now I can proceed with building the robot. Again, put a cable into the motor, hold it firm and put the Lego pieces back. Now I'll do the same thing on the other motor. This is quite a good technique to have the cables in place and you could use it in other constructions as well. Their purpose is to hold the cables firm so, before we proceed with building the robot, we have to take them out, take a cable, put it into the motor, hold the cable firm and put the Lego pieces back. First of all, we have the two large motors and you may notice that there are these Lego pieces at the back of the motors. Now, I'll assume that you have already built the modules and I'll go through the process of assembling them and focus on some of the key features of the construction. There is also a pdf file where you could find instructions on how to build the whole robot. It consists of two large motors that drive the robot, one medium motor that could be used to power additional attachments, two light or color sensors for orientating on the field and, of course, a brick.īelow the materials tab following the video you could find pdf instructions on how to build these modules. In this tutorial I'll show you an EV3 construction that could give you ideas for building your competition robot or you could just use it as a base for your robot.
