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
