Karg and Su’s movements

Programming level 1

Wahur and Karg & Stream

P1

How to build

Construction:

  • Can be made with movable parts, without robotics

OR

  • Karg and Wahur on a robot, built behind each other.
  • The robot works with 2 DC motors: with pre-programmed movements.

  • Stream bank built with static parts, without robotics

Programming level 2

Remote-controlled chase

P2

How to build

  • Karg and Wahur on separate robots, both robots are equipped with 2 DC motors and a 4-Touch Sensor remote control
  • Karg's eyes are green, Wahur's eyes are red (LEDs)
  • The 4 Touch Sensors move the robot in 4 different directions
  • The child who controls Karg chooses the route the robot will take, the child who controls Wahur has to follow it with their robot.

  • Stream bank built with static parts, without robotics

Programming level 3

Coordinated movement of figures

P3

How to build

  • Karg flees from Wahur along the stream by line tracking
  • Starts at the press of a Touch Sensor and moves with line tracking
  • 2 LEDs (green) continuously lit – eyes
  • Wahur chases Karg along the stream by line tracking
  • Starts at the press of a Touch Sensor and follows a different, longer line
  • 2 LEDs (red) continuously lit - eyes

  • 1 Touch Sensor to trigger the movement of the stream.
  • 3 LEDs (blue) for water.
  • 1 DC motor to move the stream and tree using gears.

Wahur

P4

How to build

  • The two robots are built and operate as in P3
  • Wahur's head and tail move with servo motors and is equipped with a sound sensor
  • Karg follows a line as in P3
  • Wahur first follows with head down and tail held high. When he hears a splash (Sound sensor), he starts running backwards with his head up and tail wagging

  • As P3
