Build a pilgrim on a bike and control it & Build a runway for the plane to take off
P3
How to build
Bike
Use a similar structure as in P1
Use a mother board, 1 DC motor, 2 Touch sensors on two sides of it and 1 servo motor in the handlebars
The bike should start to move when the robot is switched on
The servo motor should turn to the direction of the pressed Touch sensor and return to the basic position when both Touch sensors are released
Airplane
The runway is built of drive rails, at an ascending angle
Use a motherboard, 2 DC motors, gears as wheels. 1 LED and an IR Photoreflector for detecting the end of the runway
The aircraft starts automatically on power-up and rolls to the end of the runway, illuminated, at an increasing speed. When it detects the end of the runway, it stops.
