Do you have previous experience in building lego mindstorm robots?

Yes I have previous experience in building lego mindstorm robots as I am a mechanical engineer. Prepare the building space. It should be then well lit. You will then need something to just build in or on to just prevent missing pieces. A towel will then keep pieces from the bouncing and then make them easy to just spot. A low, wide cardboard box will then make it easy to just keep track of the parts. Having few plastic containers on your hand which may be useful for the sorting parts. Remove your Mindstorms computer brick and then set it aside. Place it with the sensor systems, batteries and the cables. Sort the remaining parts by the task. Place wheels, axles and the tires in their own area. Likewise, place the struts and then blocks apart. Smaller the moving pieces, such as hinges and pivots, should also be very well grouped together.
