SCOUTING IN THE BOTANICAL GARDEN

Programming level 1

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

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

Guards on the bridge

Crossing the lake by boat

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

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

Boat with a rowing boy

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.
