Sadly, there are no pictures or videos today!
Our car is still in the process of being built. It's doing pretty well: the current iteration travels ~2 m in 10 s (an improvement from 12 s!)
Basically, we take a motor, and attach a gear train to it to prevent the motor from stalling. It has to carry 1 kg!
Our current gear train is a 15x gear train (one 8 tooth to 24 tooth, and another 8 tooth to 40 tooth). We have a triangular type car with a little wheel in front and two large wheels in the back.
We've discovered that 9x is too little, so next week, we're going to try a 12x gear train!
