This crane shares alot of similarities with Remote Control Crane It has the same engine program exept it uses the color sensor to turn the engine on and off, a green ball turns it on, and a red ball turns it off.
It can turn 360 degrees and has stabilizer jacks.
Motors turn the turn table, lift the boom, raise and lower the gripper and, open and close the gripper
The boom and gripper are raised and lowered with string.
This is a top view of Mobile Crane ready to travel.
This is the gripper.
This is Mobile Crane with the gripper lowered.
How it works:
It makes an engine noise by using the color sensor. It uses two touch sensors and the orange NXT button to turn the crane and raise and lower the boom. If the ornage NXT button is pressed it reverses the direction that the motors turn.
This is a movie of Mobile Crane loading a pack of bullets.
