Some machines may be operated by computing devices that include touchscreens, and a graphical user interface (GUI) is provided for enabling control of the machines.

If contact with the touchscreen is broken (e.g., for more than a threshold amount of time), the machine operation may be halted, and the process to initiate operation can be performed again on the touchscreen to cause the machine to resume operation.

Abstract: Examples are provided that describe a cycloid transmission with an adjustable ring. An example cycloid transmission includes a disc and a motor shaft attached to the disc. The motor shaft is capable of rotating the disc around an outer ring of rollers. The outer ring of rollers surrounds the disc.

A circumference of the adjustable ring can be adjusted in order to cause expansion of a radius of the disc. This expansion will result in increased contact of the disc with the outer ring of rollers and thereby lower backlash during rotation of the disc.
