The design for the Robotics/Control system

For this post I will be talking about the design and implemenation.

Most of the groups who were taking part in creating a control system chose to build the ShooterBot. We were given instructions which came alongside the Lego Mindstorms kit. The robot is designed to shoot small plastic balls from its 'shooter' at different targets depending on what the program/software has instructed it to do.

Once we had built the ShooterBot we could choose from a selection of sensors. We could of chosen from many sensors such as light, pressure and ultransonic. After talking about it as a group we decided to go forward with ultrasonice and pressure sensors as we had to make it use two sensors. The sensors were important to us for the tasks we wanted the ShooterBot to do.

We had tested different settings to see what worked in various situations. For example we wanted to know how far the Robot could shoot the coloured balls. We wanted to know how accurate it was. These were key to finding out the capabilites of our control system. The sensors might not have worked past certain measurements so we decided on 20centimetres. The pressure sensor was programmed by us so that when it begins to be pressed it will search for targets within 20cm. It will then loop and begin again.
