Build: The Frog and the Dragonfly

This is my 6th robot to the MINDSTORMS EV3 set. It's a frog which is chasing a dragonfly.

The frog has the Infrared Sensor in the nose switched to IR Beacon mode to detect the dragonfly - see on picture 3. The dragonfly has the Remote Beacon hidden in the body (between the two wheels - see on picture 5).

When the frog detected the dragonfly it starts to move toward. For doing this it has 3 wheels, two on each front legs and the third is holding the back - see on picture 2. The frog is pushing itself with the two back legs, rolling on the wheels. The medium motor is rotating the two legs at the same time, they are connected at the back of the body - see on picture 4. Each back leg has a large motor to push and control a bit the movement.

This build expands the original sets animal theme :D
