This adapter makes it possible to use LEGO® wheels with the Pololu 120:1 mini plastic gearmotors (offset output and 90-degree output) and the Solarbotics GM6 and GM7 gearmotors. These are great motors for building small robots, and LEGO makes a number of very high-quality wheels as part of their Technic and Mindstorms product lines, many of which would also be excellent for use on a small robot. With this adapter, you can integrate LEGO® wheels of your choice into a robot. Pololu sell the adapters in pairs, so that you can make a two-wheeled robot.
The adapter fits very tightly to the metal axle of the gearmotor, so that it will remain attached to the gearmotor when the wheel is removed. Pololu recommend that you leave the adapter permanently attached to the metal axle; repeated removal and insertion may loosen the connection, causing slippage.
The adapter is made of ABS plastic, similar to the plastic used in LEGO® blocks. Its dimensions are shown in the following picture:
The adapter can be used with any LEGO® wheel that accepts a standard axle, as long as the tire does not extend more than 0.35" beyond the inner edge of the hub so that the motor body will not rub against the tire.
