My Original Forklift was part of my NXTLog FoodFactor Competition Entry, which needed a method to transport models of the large open top pallet type bins used to transport vegetables, such as potatoes, cabbages and pumpkins. I decided on a Forklift Truck to do the job.

LEGO Mindstorms NXT Forklift - Mark II

I felt that the original Forklift’s Mast Lifting and Lowering Mechanism could be further improved to give better clearance and reliability. As a result of my tinkering this was achieved, along with a more stable Mast set-up. The modifications are relatively minor, but results in a better robot as a whole.

Like the original version of my forklift, this one also uses the LEGO Mindstorms NXT compatible Rotacaster at the rear for precision tracking and steering.

I’ve attached a LEGO Mindstorms NXT Colour Sensor to allow your Forklift to follow a line. By using coloured blocks on your line you could have the Forklift load a container, carry it of to a new location, unload and return to base. There’s some NXC Code below to get you started. I leave the rest to you…….
