This is a sturdy little robot that I made a while ago that can get over anything. Well, not exactly, but it can get over dictionaries! It has 4 treads that can pivot freely, enabling it to have great traction when driving over books etc. Here’s the movie:

I have been meaning to buy myself the crawler crane set (8288) for ages, but Lego discontinued them in the UK at Christmas 2007. However, after spending my £5 Lego voucher in my local Lego shop yesterday, I went to Toys R Us and to my great surprise, they had ONE left in stock. So I bought it.

And I must say, this is one of the best sets I have ever bought (apart from the NXT). It took me about 70 minutes to build, and it spent last night guarding my phone on my desk. Today I will build the second model that can be made from the set, and then tomorrow I will set about sorting out the pieces, so I can use them in my upcoming Mindstorms Models.

I had originally built a Power Functions Version (Found Here) but I had to use the Power Functions parts for another creation, so I incorporated NXT components into it. Doing this was relatively easy because I tried to make the design very modular. The Power Functions turned out to be much more powerful than the NXT motors.
