Patent number: 9957002Abstract: A mobile platform intended for civilian, industrial, research or other use. An ambulation system or mobile platform such as for traveling over uneven terrain includes one or more leg arrangements attached to a main body or chassis. In an embodiment, a leg arrangement comprises one or more legs, such as legs that rotate in the same and singular direction around their respective rotary joints when the vehicle is moving in a single direction. The rotational axis for both legs is located near each other and preferably coaxially and allows ground contact of two or more legs at all times.Type: GrantFiled: February 1, 2016Date of Patent: May 1, 2018Assignee: Genesis Robotics LLPInventor: James Brent Klassen

Patent number: 9945458Abstract: A motion producing device comprising an output member with a contact surface and a reference member. An actuator member is attached to the reference member, the actuator member having a traction surface and comprising actuator zones, each actuator zone being energizable to move a corresponding portion of the traction surface to change a contact state of the traction surface with the contact surface depending on an energized state of the actuator zone. An energy source is operatively coupled to the actuator zones for sequentially changing the energized state of the actuator zones. The actuator member provides a torque transmission path between the reference member and the output member.Type: GrantFiled: June 19, 2013Date of Patent: April 17, 2018Assignee: Genesis Robotics LLPInventor: James Brent Klassen

Publication number: 20170338705Abstract: An electric motor has a first carrier having an array of electromagnetic elements and a second carrier having electromagnetic elements defining magnetic poles. The first and second carriers each define an axis. An airgap is formed between the first and second carriers when in an operational position. An inner thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. An outer thrust bearing connects the first and second carriers and is arranged to allow relative rotary motion of the carriers. The electromagnetic elements of each of the first and second carriers are arranged radially inward of the outer thrust bearing and radially outward of the inner thrust bearing. The inner thrust bearing and the outer thrust bearing are arranged to maintain the airgap against a magnetic attraction of the electromagnetic elements of the first and second carriers.Type: ApplicationFiled: April 13, 2017Publication date: November 23, 2017Inventors: James Brent Klassen, Damian Spasov, Bradley Christopher Pope

Publication number: 20170184190Abstract: A flex spline torque transfer device has a flex spline that is deflected in the radial direction by magnetic attraction to form a wave. The flex spline may be deflected radially inward by magnetic attraction to form a wave. The flex spline (FS) may be deflected radially inward by magnetic attraction at one or more positions equally spaced around the FS inner diameter (ID). The attraction may be greatest at smallest radial air gap between FS and magnetic means and lowest at largest air gap. The magnetic means may or may not be actively commutated. The highest magnetic force may be determined by the smallest air gap. In another embodiment, a torque transfer device has a flex spline that is deflected radially inward by magnetic attraction to a permanent magnet means at one or more positions equally spaced around the FS ID.Type: ApplicationFiled: May 6, 2015Publication date: June 29, 2017Inventor: James Brent Klassen

Publication number: 20170181916Abstract: An exoskeleton suit allows a user to control the legs using the arms. Preferably, there is two-way feedback/control between the legs and arms causing movement of leg joints to be proportional to movement of arm joints. Haptic forces and control forces on the joints may also be proportional. The relative magnitudes of the movements and forces may be adjustable. Rotary or angular actuators may be used. A twisting actuator is also provided using a pair of bending actuators mounted side by side to provide torsional displacement of frame members. The ability to support a portion of the user's weight on the hand grips is possible while simultaneously controlling the lower body movement by applying pitch, roll and yaw movements to that hand grip.Type: ApplicationFiled: May 5, 2015Publication date: June 29, 2017Inventor: James Brent Klassen
