CranoBotter Lego Mindstorms NXT Crane

A semi-robotic crane I built with Lego Mindstorms My first NXT project (after playing for 30min with the "start here" box content) is a crane. I decided that it was much better to start off with a stationary model, so I didn't have to run after the robot in case the programming was wrong. It started off as RC only Project. The goal was to have a little crane, very similar to standard construction crane, in my room that I can control via Bluetooth. Now that it is finished it has some more features:

 Remote control via OnBrick on Laptop or Windows Mobile device
 Three fully functional axes: Rotation, move hook away and towards crane, hook level.
 Enough string to lift load from 4m below
 Software coordinate system to keep track of coordinates while using OnBrick remote control
 Movement restriction for hook level and movement towards and away from crane, so the crane can't destroy itself.
 Adjustment of zero coordinates at beginning
 Load/no-load sensor
 Two Programs in NXT-G (Lego Software): All manual mode program and a program with auto drop at zero coordinate as soon as load is sensed (this program does not care what height you pick up load from and what height it has to drop it off to, it will always come back to zero coordinate).
 Load up to two AA batteries and Lego crate.
 Speech like: "CranoBotter at your service" or "Zero Set"
 Dynamic display with custom .ric files
 Cool design with NXT Brick as counterweight

I would like to thank my parents for this Christmas present (NXT-kit) and the nxtasy.org forum community for support.

Yes I have OnBrick on my phone. It is a Windows Mobile application. I think there is no port for other platforms. Standard .cab installation

[YouSunkMyFishy]

Very nice, but pretty slow. Yeah I noticed you sped it up. But that's okay, cranes can be slow.

@sifferking Where can you download it

[Dymys200]

[Jazaaam]

hey does it involve any money to be spent to get the OnBrick application on your phone

[applefan2411]

How did you make the hook get closer and farther from the crane.
