  • Occurs at 27 or 49 Mhz. Crosstalk with other RC, but not other noise such as electronic or engine [1]
  • Modern controllers go over Ghz freq of 2.4, same as internet. [2] This is much more robust.

OSE Requirement

First use cases for OSE are remote control, mission planning, wiring simplification applications:

  1. Excessive time under full throttle operation at 70+ hp skid loaders doing aggressive digging result in nausea after several hours - data point from MJ. Remote control operation of the machine from that point onwards, or starting with remote control, can address the bodily injury potential. The disadvantage of RC operation is not being able to see the work as close up unless one is very close to the machine. In close proximity of the machine, the operator must use precaution to avoid getting run over by the machine, so there are inherent safety risks of close-up remote conrol in certain use cases like this.
  2. Mission planning. In certain use cases on a clear site, a machine can be programmed for fully automatic mission control tasks. However, positional feedback with beacons would be required so that auto-correction of path execution can occur. Ardupilot supports Position Beacons.
  3. Wiring simplification refers to certain machines where RC control simplifies wiring by eliminating the need af physical wiring connections. This works well for modular systems where functions can be separated into multiple units by principles of modular design. A use case in question is a 360 degree backhoe. The complexity of such a device revolves around the need for hydraulic connecion where the connecting hoses must spin 360 degrees. This is normally accomplished by 360 degree swivels. The minimum number of hoses required is 4 (2 hydraulic circuits in absence of motor case drain). See Live Swivels.
