This adapter is designed to make it possible to use LEGO wheels with the Solarbotics GM6 and GM7 gearmotors. The GM6 and GM7 are perfect 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. We sell the adapters in pairs, so that you can make a two-wheeled robot.
Instructions
- Fit the adapter onto the metal output shaft of a GM6 or GM7 gearmotor. You will need to push quite hard; be careful not to damage the gearmotor.
- Slide the other end of the adapter into a LEGO wheel of your choice.
The adapter fits very tightly to the metal axle of the GM6/GM7, so that it will remain attached to the gearmotor when the wheel is removed. We recommend that you leave the adapter permanently attached to the metal axle; repeated removal and insertion may loosen the connection, causing slippage.
Our LEGO wheel adapter is made of ABS plastic, similar to the plastic used in LEGO blocks, but it is not as strong as a LEGO part. Its dimensions are shown in the following picture:

The picture at right shows a view of the LEGO wheel adapter attached to a standard LEGO Technic wheel in which the tire is aligned with the inner edge of the yellow hub. The adapter may 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.
