Motion

REV DUO Motion Motors provide the rotational power. Gears, sprockets, and wheels transmit and transform that power. Bearings reduce the friction along the way. A useful motion system is many of these parts working together.

5mm Hex Shaft

The core to transmitting motion in the REV DUO build system is the 5mm hex. This hex is incorporated into the other motion components, such as: sprockets, gears, wheels, and shafts.

Three Ways To Transmit Motion

Sprockets and chain, gears, and belt and pulleys compared

Sprockets & Chain

Transmit torque across distances with flexible lengths.

Gears

Good in compact spaces and for changing the direction of rotation.

Belt & Pulleys

Efficient at transmitting motion at high speeds for fixed lengths.
