Lego Mindstorms Robots

Basic Model

Before beginning to use the robots as a swarm a base model had to be created. After some time we came up with a simple but effective design, this model is shown in the following picture:

As can be seen it uses track tyres and two seperate motors to make sure the robot can move forward, backward and turn. This system was chosen as our design was focussed on simplicity and this model negates the need of a steering system or a swivelling wheel.

After building these basic units we needed to find out what extensions were possible, after some digging in the several boxes of lego bits we found the following actuators/sensors:

• Motor (actuator)
• Infrared distance (sensor)
• Axial Pulse Counter (sensor)
• Pressure sensor (sensor)
• light sensor (sensor)

Ofcourse in the swarm idea communication is a must, this will be further discussed in communication.
