Description

2mm shaft adapter connecting a LEGO wheel to a 120:1 mini plastic gearmotor with 90-degree output

Overview

This adaptor 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 adaptor, 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

  1. Fit the adaptor onto the metal output shaft of one of the four gearmotors linked above. You will need to push quite hard; be careful not to damage the gearmotor.
  2. Slide the adaptor into a LEGO wheel of your choice.

The adaptor fits very tightly to the metal axle of the gearmotor, so that it will remain attached to the gearmotor when the wheel is removed. We recommend that you leave the adaptor permanently attached to the metal axle; repeated removal and insertion may loosen the connection, causing slippage.

Dimensions

The adaptor is made of ABS plastic, similar to the plastic used in LEGO blocks. Its dimensions are shown in the following picture:

The adaptor can be used with any LEGO wheel that accepts a standard axle, as long as the tyre does not extend more than 0.35" beyond the inner edge of the hub so that the motor body will not rub against the tyre.
