The ruined city

Programming level 1

a) Build the characters in the scene as in P1

The 3 members of the monkey troop, mounted on a servo motor, rotate left and right
A green LED is mounted in the trees which blink when the monkeys move
The movement is triggered by a clap, which is detected by a Sound sensor

b.) The leader monkey moves back and forth on a track with drive rail, with 1-1 DC motor and gears on its arms, in the ruined city

Build the labyrinth of the ruin city, at the end of the labyrinth the monkey troop as in P2 a.)
Build Mowgli on a robotic base, equipped with 3 IR Photoreflectors, 2 red LEDs
Maugli has 2 IR Photoreflectors (mounted front-side right and left) facing the sides of the maze, so the robot can keep its distance from the walls and move towards the exit to reach the monkey team.
The third IR Photoreflector is mounted facing forward. When it detects the monkey troop, Mowgli stops.
The 3 members of the monkey team, mounted on a servo motor, rotate left and right while the green LED flashes, automatically starting the program when switched on.

Build the tree-climbing leader monkey
Its structure is the same as in P2 b), but it has 1 IR Photoreflector and 1 sound sensor.
The robot starts when a clap is detected by the Sound sensor and stops when the IR photoreflector detects the end of the trajectory.

The Chief monkey is a robot that can dance thanks to 4 servo motors built into its legs.
The coordination of the 4 servo motors, the continuous balancing of the robot and the accurate measurement of the values allow the robot to stay on its feet and not to topple over.
The monkey starts move its feet, when clapping is detected by a Sound sensor.

Building a monkey clinging to a tree.
The DC motor mounted on the robot is connected directly to the battery holder.
The two arms of the monkey alternate with the DC motor and axes driven asynchronously (one hangs, the other moves forward).
The robot thus moves forward suspended on the outstretched rope.
