6x6x4 Robot vehicle

[SecondHandLego]

My first technic MOC after rebooting my Lego hobby. It's not finished - it has no program - but I am declaring it finished anyway. It was a nice project to get acquainted with the 2000s technic Lego.

The robot is made of a Mindstorms NXT 2.0, a Mobile Crane Mk II and some additional parts.

Interesting, I wonder what you could program it to do.

looking good. I suggest you should enter it into [TC11]

He can't use it for TC11 because Mindstorms aren't allowed. 

Yup, could make a cool rover though...

Well, it can scan it's environment, try out where it can go and make a 'mental map' only based on distance readings, calculations of how far it has gone in which direction, and registrations of where it has bumped into something. The robot doesn't do a lot seen from the outside, but it will be quite complex to program. It drives more or less like a car, so it can not make turns on the spot like some robots do.

Right now, it doesn't have a camera, but if it had it could be a serveillance rover.

Thank you all for your feedback! I didn't know about the TC11 (am not that often on this website) but indeed, it has a mindstorms inside. Perhaps it's not that difficult to replace the engines and the computer-brick by remote control and regular engines. However, this one is also too big to participate - 57 studs long.

How many motors does this use, and how did you get drive, I see that it looks like 2 motors are used for steering, and 1 for turning the "head" so what about drive?

One is for steering, which sits at the front but powers steering both at the front and the back end. The engine for driving sits at the back but drives all six wheels.

Thank you everybody for your interest and kind words! It encouraged me to improve the design. Earlier, I reported that the robot didn't have enough taction. That problem is solved now with a different gearbox in the centre module.
