Turning to gear ratios, you’re now an expert at doing the math, but you’re probably wondering how to determine how many teeth this worm gear has! 4, we turn the worm gear axle slowly by exactly one turn, at the same time watching the 24t gear. This is the answer you were looking for: the worm gear is a 1t gear! So, in this assembly, we get a 1:24 ratio with a single stage. In fact, we could go up to 1:40 using a 40t instead of a 24t. The same high friction also makes this solution very inefficient, as a lot of torque gets wasted in the process.

Is this thing really a gear? Yes, it is, but it is so peculiar we have to give it special mention. 4, you can see a worm gear engaged with the more familiar 24t. Try and turn the axles by hand. The reason for this asymmetry is, once again, friction. Is this a bad thing?

But what really makes LEGO easy to use is its modularity. You don’t need a ruler or a square— all that’s required is that you can count! They are ready to use, just pick up what you need from the box. This is a very important point to make to the people who live with you if you want them to be tolerant of your hobby! ■ LEGO is cost-effective You can use and reuse your LEGO parts as needed to produce many generations of robots. There are other easy-to-assemble robotic kits on the market, but they usually only permit you to build one specific model.
