Rainbow Astro is part of Rainbow Robotics, a professional mechatronics company providing robotic system engineering technology. The development of their telescope mounts is based on humanoid robotic technology.

The Rainbow Astro RST-300 uses a drive system new to small telescope mounts to drive both axes. Strain wave gears are commonly used for industrial robots. Strain wave, or harmonic, drives are based on the elastic mechanics of metals. They provide high reduction and high torque in a compact, lightweight package. In addition, the drives have essentially zero backlash with a long, sinusoidal error that makes them perfect for guiding.

Rainbow Astro RST-135
Harmonic Drive
A strain wave drive consists of a motor, a circular spline, a wave generator and a flexible or "flex" spline. In the animation on the left, the circular spline is blue, the wave generator is green and the flex spline is red. The circular spline is fixed, the flex spline is attached to the output shaft, and the wave generator is attached to the motor. Ball bearings are located between the wave generator and the flex spline.
Due to the high torque of the strain wave gear and motor, counterweights are not needed for loads under 66 lbs. (30kg). Strain wave gears are commonly used for industrial robots. The mount weighs only 18.7 lbs. (8.5kg) and measures only about 18.3 x 17.5 x 27.9 cm. Rainbow Astro calls this breakthrough mount a "Weightless Mount." With the RST-300, volume and weight of the mount is no longer a problem for traveling astrophotography and visual astronomy.
The mount can be operated in either equatorial or Alt/Azimuth modes making it ideal for both imaging and visual use.

WiFi (hotspot) and GPS (location and time) are built into the mount and home sensors are used to place the mount in the specified home position.
