The hardest problem on the mechanical side was connecting the motor to wheels. You will often need to gear down a motor before you connect it to the wheels. Without the ability to custom manufacture parts it is very difficult to cobble something together. The simplest solution is to buy a motor with a prebuilt gearbox, axel, and wheel. I don't remember where I got mine but something like this should work: http://www.amazon.com/KNex-Dragster-Racecar-Rally-Series/dp/B0024H3Z2M/ref=pd_sim_t_5 http://www.amazon.com/KNex-Dragster-Racecar-Rally-Series/dp/...
- jaryd 14y agoThank you for the tip! I was actually just reading about gearing in an article called "The Art of LEGO Design" (http://cheme.eng.wayne.edu/neuron/LEGO_ROBOTICS/artoflego_article.pdf http://cheme.eng.wayne.edu/neuron/LEGO_ROBOTICS/artoflego_ar...)! Was also looking at Technic kits (such as http://shop.lego.com/en-US/Tractor-9393 http://shop.lego.com/en-US/Tractor-9393) with a preference towards those with more pieces, and thus more flexibility.
- doctoboggan 14y agoThat paper is great, thanks for sharing! It looks like I need to buy some lego technique parts.
