A robot a 'day'. Work with gears. Lift objects Pro Preview

We are sure you've seen the gears in the LEGO Mindstorms EV3 sets. They are pretty easy to use. Just add an axle and you can now rotate them. Add two gears working together and you can do miracles, like a magician. And if you put them perpendicularly to each other it gets very interesting. This is our goal with the MotoCar robot in A robot a 'day'.

Gear wheels for lifting

We use the gears to construct a mechanism that could lift objects. The gear wheels are placed perpendicularly. One is the driving wheel and the other is the driven wheel. When the motor rotates, the fork at the front will move up and down. 

Balance of the construction

Notice how there is an additional frame at the bottom front of the robot.

The purpose of this frame is to keep the robot from falling. What will happen if you remove this frame? How will this influence the behaviour of the robot? Well, the robot will fall. You should always construct robots that are well balanced. and do not fall in their normal...day to day... activities.
