We continue from part 3 where we finished part of the 'rear'. Power is transfered from a motor to the wheels but having about 16 gear wheels makes it more than complex for this LEGO Mindstorms EV3 Competition robot.
One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects.
In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.
The second construction of the series along with a comparison with the first construction. The new robot requires more parts, but has a few more advantages.
We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We would be making mistakes, showing them and taking up the challenges right in front of your eyes. The first construction would not be perfect but we would eventually arive at it.
Next important state is Turn Right with our robot. This happens when we detect a line on the right.
In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.
With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build.
