BB2B

The BB2B example is inspired by the vehicles invented by Valentino Breitenberg. He created a number of conceptual vehicles which show life-like behaviour. By connecting sensors and motors together in a specific way, different behaviours can be observed.

All code for this is also found in the Roboid Control repository as the BB2B example. 

Our goal with this example is to make a robot which moves around in a space autonomously, avoiding objects. 

How it works

Each wheel will either rotate forward or backward with a fixed speed. When the robot is not colliding, both wheels will rotate forward and thus the robot will move forward.

As both switches are placed at the front of the robot, they will be able to detect whether the robot collides with something. Depending on which switch is closed, the robot will behave as follows:

• Left swich is closed only: the robot will turn right
• Right switch is closed only: the robot will turn left
• Both switches are closed: the robot will drive backward

All of this is achieved by letting the left switch control the right motor and the right switch control the left motor. When the switch is open, the motor rotates forward, when it is closed, the motor rotates backward.

You will see that with this setup, the robot will be able to move around the space quite well. 

For the next step, you can choose your preferred language. Each path is a bit different but the end result are compatible (and can even be combined!).
