Systems and methods of wheelchair systems having a companion control mode are disclosed. The wheelchair system includes a companion and a wheelchair. The wheelchair includes one or more wheels, at least one actuator coupled to the one or more wheels, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine the companion, generate a companion profile based on the determined companion, determine a movement of the companion, and actuate the at least one actuator to drive the one or more wheels to follow the movement of the companion. The actuation of the at least one actuator to drive the one or more wheels to follow the movement of the companion is an autonomous control.

Wheelchair systems and methods to follow a companion

Systems and methods of wheelchair systems enabling fine manual motion control are disclosed. In one embodiment, a wheelchair system includes a wheelchair. The wheelchair includes one or more wheels, at least one actuator coupled to the one or more wheels, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine a wheel torque on the one or more wheels, determine a compensation value, and actuate the at least one actuator applying the compensation value to the one or more wheels to remove at least a portion of the wheel torque such that less external force is required to physically move the powered wheelchair than when the compensation value is not applied.
