Available resources
Gears and Ratios
Follow a scaffolded investigation of gear trains, gear ratios and mechanical advantage. Students apply speed, direction and torque reasoning to a design challenge. The…
Robort Arm Torque Explorer
Explore a robot arm's torque requirements as loads and arm geometry change. Students examine the effect of lever length and weight on the torque needed to hold or move…
Robotics Competition
Students choose wheels, motors, battery and sensors, build priority-based control rules, run a simulated competition course and evaluate performance, reliability and…
Ultrasonic Sensors
Students investigate how an ultrasonic sensor uses round-trip echo time to estimate distance, then calibrate noisy measurements and use a distance threshold to stop a…
