Week 5 _ Robotics

​This week was another big week in Capalaba Robotics Club! In this lesson we learnt how to code a robot to follow a black line and how to use the Ultrasonic sensor.
 
Firstly we looked at how a robot “sees” a line compared to a human. A robot can only see the line if it is constantly comparing the line against the floor, so moving forward in a zigzag. Next we moved on to learning how to code the robot and testing our code on black circles taped to the floor. It was a difficult challenge, but everyone got the hang of it in no time!
 
The second part of the lesson was learning all about the ultrasonic sensor. Firstly, the participants attached the ultrasonic sensor to their robot and we had a discussion about what it does, which is the robots eyes. The challenge was set that participants must code their robot to move until the robot senses that a wall is 20cm away. Which was a lot of fun! Participants figured out that not only will the robots stop at the wall, they will stop at any obstacle in the robots way. The next challenge was to code their robot to sense when the wall was 20cm away and then move backwards.
 
Everyone did a fantastic job of staying on task and getting their work done. This is the last lesson that we will be learning about the skills needed for the Sumobot competition.
 
Next week is the beginning of the sumobot challenge. They will be constructing and testing their code ready for the last week of Robotics Club, which is when the challenge will be held.
