Robotics / Engineering – I was catching up with my classes today, after missing three days last week. For physics I was lucky to get a physics substitute teacher, and she went over inertia and a spring force lab. In science 8, students continued with their infectious disease research projects.
The photo above is a photointerrupt sensor that I’m trying to get more of for our robotics club. Kids are putting together 2wd robot chassis controlled with Arduinos. Eventually I’d like them to try and use wheel encoders for controlling motor speed. I need more of these sensors to match the encoder disks on the wheels.
