Week four

In Code Club this week participants learnt to code or drive a Sphero (robotic ball) through a maze. The participants started the lesson with learning how to code their Sphero and then participants could either code or drive their Sphero through a maze that was set up by the presenters. The participants found this both difficult and incredibly fun.
 

This week in robotics, it was time for the participants to learn how to code their robot to follow a line. It may seem simple to us, but the robot can’t “see” how a human does. It sees by comparing colours, touches, and distance to see or feel the environment and then act on the code it has been given. For example, if the robot was to follow a black line on a white background, the robot has to use its colour sensor to detect the two colours, move forward and make a decision of “if I see white, turn left” or “if I see black, go right”, essentially moving forward doing a zig-zag on the floor. The participants were definitely up to the challenge.

​The participants first started the lesson with learning about switches (the decision making code block) and how it can be used to get the robot to follow the line on the floor. Once the participants learn how to go down the line, the challenge was then to get the robot to go twice around the black line by getting the robot to stop after going a certain distance. The second challenge was all about testing, changing the distance, and re-testing the robot. The lesson was again a success!

Well done again participants for rising to the challenges that we set each week and succeeding. ​
