Robot wheels with rubber band treads

thingiverse

Robot wheels are designed to fit snugly over N20 motors, ensuring a secure connection. These 3D printed car wheels should fit any motor with an N20 size designation. To achieve optimal performance, use a Pololu micro metal gear motor, as they offer better motor brushes and longer lifespan compared to generic alternatives. I highly recommend using Pololu's products for their superior quality. For the rubber tread, attach a 1/2" wide rubber band, which should fit a 5COL small Ranger Band. This type of band is available on Amazon or through 5COL.com at an affordable price point. Ranger Bands are cost-effective, with a pack of 40 small sizes costing less than $10. N20 motors, on the other hand, range from $10 to $20 each and come in various gear ratios and voltage ratings. When choosing an N20 motor, consider adding an encoder for enhanced functionality. However, keep in mind that these motors will no longer fit my no-tools motor mounts if they have an encoder installed. If you're looking for slightly larger robot wheels, search Amazon for "Lobster bands." At the time of writing this, a pack of around 500 lobster bands can be purchased for $20. Please note that I do not have any affiliation with 5COL or Pololu. I simply appreciate their products and recommend them based on their quality. To prevent tread slippage, apply a thin layer of rubber cement under the rubber band and let it set before use.
