Abstract
A powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.
Claims24
A powered balancing mobility device comprising:
- a plurality of redundant processors processing movement commands for the mobility device, each of the plurality of redundant processors receiving sensor data;
- and
- a voting processor executing on each of the plurality of redundant processors, the voting processor receiving the sensor data from each of the plurality of redundant processors, the voting processor determining valid data of the sensor data based at least on whether the sensor data are within a pre-selected range, whether the voting processor has received invalid of the sensor data from an associated one of a plurality of sensors, and whether there are communications among the plurality of redundant processors;
- wherein the plurality of redundant processors computes the movement commands based at least on the valid data.
1 more element
A powered balancing mobility device comprising:
- a plurality of redundant processors processing movement commands for the mobility device;
- at least four batteries;
- a power source controller including connections for the at least four batteries, the power source controller receiving power from the at least four batteries, the power source controller managing power to the plurality of redundant processors, the power source controller including at least one sensor collecting current data and voltage data for the at least four batteries;
- and
- a plurality of modes governing the movement commands,
- wherein the plurality of redundant processors determine which of the plurality of modes the mobility device can enter based at least in part on the current data and voltage data.
3 more elements
A powered balancing mobility device comprising:
- a control device;
- a controlled device including
- a plurality of redundant processors processing movement commands for the mobility device, each of the plurality of redundant processors receiving data from the control device;
- a second protocol relaying commands specific to the controlled device from the control device;
- a first protocol supporting communications between the control device and the controlled device, the controlled device being physically remote from the control device, the first protocol transparently tunneling messages formatted in the second protocol and encapsulated within messages formatted according to the first protocol for transmission and reception;
- and
- a communication message manager identifying first protocol messages and extracting tunneled second protocol messages.
