Build a crane that can lift objects one and a half times its weight to a height of 4 inches. Tip 1: What is the relationship between torque and gear-size? Tip 2: Remember, rotation sensors can track the angle turned by the motor. Resources Crane lesson plan (PDF)
Think of a way to design and construct the stubborn car: a car that will always return to its original place no matter how far it is rolled away from its starting point. Tip: How can you track the rotary motion of the car’s wheels? This challenge provides a great...
The goal of this activity is to make a robot car drive in a square path. Hint: Rotation sensors are great for controlling the angle of a car’s turn. Resources Square lesson plan – NXT-G (PDF) Square lesson plan – RCX + ROBOLAB (PDF)
How could you design and construct a windmill connected to a rotation sensor to measure the speed of the wind? Tip 1: Even though they can be used as rotation sensors, the NXT motor and the EV3 large motor will not work as well as an RCX Rotation Sensor...
