We finally did it- 2 ‘bots running across the floor at the same time I setup one of the line-follower IR sensors on a standalone Pi and 2 club members went and printed off a zebra crossing pattern on a piece of paper and played with passing it in front on the sensor and showing how it reacted to light and dark stripes.
I’ve knocked up a ‘bot simulator to show the club members the basic concepts behind line following
Other Roboteers were amended the Scratch code to alter the amount of steering left/right increased/decreased the value sent to the motors so that they could control it better manually.
We then had each team member run a race across the room and the boys narrowly won 3-2.
The next club is in 2 weeks and I WILL get the line followe sensorts fitted. We plan on painting a black line down some white wallpaper and using it as a track.
