Abstract

A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.
