Programming level 3

Building and coordinating moving figures

P3

How to build

  • The harvester walks around the wheat field, stopping at intervals to swing his scythe. The wind blows through the wheat field and birds flutter around the tree next to it.
  • Harvester: Touch Sensor starts the program.
  • It uses an IR Photoreflector to track a line.
  • Stops at predetermined intervals and uses servo motor to perform swinging motion.
  • Wheat field: Touch Sensor triggers the program.
  • Gears driven by a DC motor move the wheat stalks and the tree with the birds.

Escape of the foxes through the field

P4

How to build

  • A combination of P2 and P3
  • The harvester is equipped with 2 Touch Sensors, he stops at random intervals, this is when the foxes must be switched on
  • The harvester stops when the Touch Sensor is pressed, turns towards the foxes and starts shouting, waving his hands. The direction of the turn is determined by which of the 2 Touch Sensors is pressed.
