SCOUTING IN THE BOTANICAL GARDEN

Programming level 1

Build guards patrolling on the bridge & Build a mechanical boat with the boys

P1

How to build

Guards on the bridge

  • Build the lake and the bridge
  • Build small figures of redshirt guards

OR

  • Join driverails to the ramp of the bridge
  • Put the guard’s figure on a DC motor that is equipped with gears as wheels and plugged into a battery box
  • The guard will move on the bridge

Crossing the lake by boat

  • Build a boat on wheels

Guards on the bridge - manual

Guards on the bridge - automatic

Programming level 2

Build guards patrolling on a cograil bridge & Build an automatic boat

P2

How to build

Guards on the bridge

  • Build the bridge like in P1
  • Build the guard on a DC motor like in P1 but connect the motor to a Studuino motherboard
  • Program the robot so that the guard would walk up and down on the bridge 5 times while the LED in its hand is blinking

Crossing the lake by boat

  • Build a robot with 2 DC motors that looks like a boat with the boys
  • Students should program it to move forvard a number of times

Programming level 3

Build guards patrolling on a cograil bridge & Build a boat with a rowing boy

P3

How to build

Guards on the bridge

  • Build the bridge and the robot like in P2
  • Add a Sound sensor to it so that the robot starts moving when it detects the whistle

Crossing the lake by boat

  • Build the robot boat like in P2
  • Build a servo motor into the waist of the boy – it will imitate rowing by leaning forth and back
  • Programme it to stop after 5 rowing movements

Programming level 4

Build the change of guards & Build a robot boat and a boy who rows up to the island

P4

How to build

Guards on the bridge

  • Build 2-2 guards on 2 servo motors – they will act out the change of guards
  • For the bridge use a baseplate, a multibase, 4 beams, 2 driverails, 1 large and 2 small gears, and 1 DC motor
  • The DC motor rotates the large gear, which 1) moves one of the driverails and the beam attached to it, and 2) rotates the small gear connected to the large gear. This small gear rotates the other small gear (in the opposite direction), which moves the other driverail and its beam in the opposite direction as the first rail.
  • The guards start on the two opposite ends of the bridge. They slide in to the center of the bridge, turn on servo motors („switching places”), then slide back out to the ends of the bridge.

Crossing the lake by boat

  • Build the robot like in P3
  • Attach an IR Photoreflector to the front of the boat.
  • The robot should move towards the island while the boy is rowing
  • It should stop when the IR Photoreflector detects the island
