MOWGLI SAYS GOODBYE

Programming level 1

The wolf figure built on a robot automatically moves forwards, waits a while and then moves backwards.
Mowgli and the others (wolves, Bagheera, Akela, Baloo) are built figures in this scene.

Wolwes

The wolf can move with gears on drive rails driven by 1 DC motor.
It is controlled by 2 Touch sensors on its back. On one of the Touch sensors it moves forward to Mowgli (according to the time measured), when attacked it makes a sound with Buzzer, on pressing the other Touch sensor it moves backwards.
Mowgli is a static robot, with 1 servo motor in one shoulder to move his arm, and 1 red LED in each hand.
On pressing one of the Touch sensors, the arm is raised, on pushing the other Touch sensor, the arm is lowered, the LEDs are lit all the time, the program starts automatically.

The structure, operation and program of the wolf is identical to a).
Mowgli is mounted on a robotic base with 2 DC motors, his arms are axial, each eye has 1-1 LED of different colour. Its program is started by pressing the Touch sensor. One of the LEDs turns on immediately, the robot moves forward and the other LED turns on.
After a while the robot stops and the LEDs switch off.
As the robot moves, the LEDs flash to represent Mowgli's cry.

Mowgli "A"

Wolf "A"

Mowgli "B"

Wolf "B"

The wolf is built as in P2
As long as the Touch sensor is pressed, the robot moves forwards or backwards
When it reaches Mowgli, it also signals with the Buzzer.
One of Mowgli's arms can be moved with a servo motor, he has 1 LED built into each hands and an IR Photoreflector i also joined to the robot.
When the wolf gets close to Mowgli, detected by an IR Photoreflector the servo motor raises his arm, the LEDs start blinking.
When the wolf moves away, the arm is lowered.

Mowgli

Wolf

Mowgli has the same structure as P3
The servo motor arm moves up and down a random number of times.
The wolf is structurally similar to P3, but has no Touch sensor.
After switching on, it waits a random amount of time before moving forward.
The IR photoreflector mounted on it causes the wolf to stop when it gets close enough to Mowgli, signal with the Buzer and then back away from Mowgli.
