Five Minute Bot

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.

Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

Build FiveMinuteBot

In this episode we will show you how to build the FiveMinuteBot. We will make a quick overview of this Mindstorm Robot.

Teacher's Notes on building the FiveMinuteBot

Notes on building the FiveMinuteBot

Importance of the construction balance on the LEGO Mindstorms robot movement

The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts. 

Importance of the wheels and tires on the LEGO Mindstorms robot movement

DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways. 

Front or Rear wheel drive for more precise LEGO Mindstorms robot movement?

Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.  

Importance of the caster ball on the LEGO Mindstorms robot movement

You could use the LEGO Steel Balls as a third wheel on the robot. It is a caster wheel. But this is steel and as we know from basic existence on this planet, where there is steel there is also rust. The steel ball could get quite rusty and this could have an influence on the behaviour of the robot
