Patent number: 11260545Abstract: Dynamic control of a center of mass position is based on replacement of discrete motion of macro body (counterweighing solid or counterbalancing mechanisms) for continuous molecular flow of counterweighing liquid. Redistributing liquid counterweight between chambers attached to independently moving parts of robot allows its motion to new stable position without disruption in static stability and dynamic balance. Various embodiments include bipods/humanoids, wheeled locomotion robots and hybrid wheeled/multi-pod bio-like robotic systems; some embodiments allow reversible mutual reconfiguration between various structural arrangements. In humanoid embodiments, method allows moving on uneven terrain or ascending staircases while maintaining static stability; method also decreases the probability of fall and secures self-rising if a fall occurred.Type: GrantFiled: October 7, 2020Date of Patent: March 1, 2022Inventor: Benjamin F.
