Remote Control Crane

Remote Control Crane is another robot that I made from instructions in a book called 

CRANE LEGO NXT (LEGO NXT building & programming guide)

By Jan Dolata and Aleksander Gruszcynski.

Remote Control Crane can lift up to 3oz and spins on a turn table.

This is a side view of Remote Control Crane.

This is what Remote Control Crane does when it picks up a heavy object.

This is Remote Control Crane's remote.

Remote Control Crane's remote uses 2 sensors.

One of them is the rotation sensor that is a part of the motor.

It reads which direction and how many degrees the motor has been rotated.

The other is the touch sensor.

When the touch sensor is pressed and the motor turns the reading (Direction and rotation) is sent to the  motor operating the boom.

When the touch sensor is not pressed and the motor turns the reading (Direction and rotation) is sent to the  motor that turns Remote Control Crane.

This is the gripping mechanism.

This is Remote Control Crane's lifting mechanism.

This is Remote Control Crane's turntable.

This is an audio recording of Remote Control Crane's engine running.

In order to have an engine I recorded a 460 horse power engine turning on, revving up, staying revved up, revving down, and turning off. 

How the engine works:

First Remote Control Crane plays turning on then it plays revving up then it plays staying revved up until the orange button on the NXT is pressed then it plays revving down and then it plays turning off.

This is a movie of Remote Control Crane picking up a basket with three batteries in it.
