Research of Gravity Compensation Mechanism based on Non-circular Gear
Jixie chuandong, 2019 At present,most robots need to consume a large amount of energy to overcome their own gravity during operation. In order to reduce energy consumption and improve robot performance,a gravity compensation mechanism（ GCM） for a rotating joint manipulator is
