Sawmill & Van

Programming level 1

Build a mechanical sawmill & Build an automatic van

P1

How to build

mechanical sawmill

  • It can be achieved by movable parts without robotics
  • The trough can be built as a simple cart with gears for wheels, rolling on drive rails
  • The tossing arm that forwards the pieces of wood to the van using a ramp can tilt on axles

automatic van

  • The van can roll up to the sawmill on 2 DC motors
  • After turning it on, the wheels rotate a number of times

Build an automatic sawmill & Build an automatic van

P2

How to build

Automatic sawmill

  • The trough can be built as a simple cart with gears for wheels, rolling on drive rails (1 DC motor)
  • The tossing arm that forwards the pieces of wood to the van using a ramp should be moved by a servo motor
  • An LED should sign the action with blinking
  • The ramp can tilt on axles

Automatic van

  • The van can roll up to the sawmill on 2 DC motors
  • After turning it on, the wheels rotate a number of times

Programming level 3

Build a sound-controlled sawmill & Build a directable van

P3

How to build

sound-controlled sawmill

  • The working process of the sawmill should start when a Sound sensor detects sound (the shouting of the van’s driver)
  • The trough and the tossing arm should be built as in P2
  • The ramp is tilted by a servo motor while an LED is blinking

directable van

  • Build a van with 2 DC motors
  • Add a 4-Touch sensor remote control to it
  • Blinking LEDs should show the direction it is turning

Programming level 4

Build a cooperative sawmill & Accelerometer-controlled van

P4

How to build

cooperative sawmill

  • The working process of the sawmill should start when an IR Photoreflector detects the van standing under the ramp
  • The whole process is the same as in P3

accelerometer-controlled van

  • Build a van with 2 DC motors
  • Add an Accelerometer as a remote control to it
  • Blinking LEDs should show the direction it is turning
