Sensorless friction and gravity compensation
2014 IEEE-RAS International Conference on Humanoid Robots, 2014In this video we present a new controller for robots, called Zero-Friction Zero-Gravity control. The controllers combine terms for compensating the forces exerted by gravity, and the forces of friction of motors and reductions. The consequence of applying this control to a robot (a humanoid robot arm in this case) result in a free movement, as if the ...

Visual servo for gravity compensation system
Neurocomputing, 2017Abstract This paper proposed a visual servo framework for the tower-crane-like Gravity Compensation System that is widely used in various aerospace ground tests. In this framework, a real-time detection algorithm is proposed to measure the position of the target.

Gravity compensation in robotics
Advanced Robotics, 2015The actuator power required to resist joint torque caused by the weight of robot links can be a significant problem. Gravity compensation is a well-known technique in robot design to achieve equilibrium throughout the range of motion and as a result to reduce the loads on the actuator.

A review on passive gravity compensation
2017 International conference of Electronics, Communication and Aerospace Technology (ICECA), 2017An articulated robot arm with multiple links will spend most of its energy on carrying its own weight when it works against gravity. A gravitational torque occurs due to the mass of the robot links and the payload, but most of the gravitational torque is caused by the mass of the robot links.

The Application of FCMAC in Cable Gravity Compensation
2005The cable compensation system is an experiment system that performs simulations of partial or microgravity environments on earth. It is a highly nonlinear and complex system. In this paper, a network based on the theory of the Fuzzy Cerebellum Model Articulation Controller (FCMAC) is proposed to control this cable compensation system. In FCMAC, without

Pilot-Force Measurement with Inertia and Gravity Compensation
Journal of Aircraft, 2007Measuring pilot force on pilot control loaders used in flight simulators is difficult due to force errors introduced by pilot control loader inertia, simulator cab motion, and gravity. Attempts to correct this problem by using strain gauges near the grip handle or in gloves have proven impractical because the devices are sensitive to grip position ...

Design of a Linear Gravity Compensator for a Prismatic Joint
2020 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2020Most existing mechanical gravity compensators have been developed for revolute joints that are found in majority of articulated robot arms. However, robots such as patient transport robots use prismatic joints, which need to handle a heavy payload.

Power-Assisted Wheelchair With Gravity and Friction Compensation
IEEE Transactions on Industrial Electronics, 2016In this paper, a gravity compensated power-assisted wheelchair (GCPAW) is proposed, which will climb a hill, and stop, and make as a delicate movement in the middle of the hill as it can do on a flat surface. To climb the hill, the proposed GCPAW compensates for the parallel component of the force of gravity (the force that causes acceleration or ...

Gravity compensation algorithms for parallel haptic interface
Proceedings. 11th IEEE International Workshop on Robot and Human Interactive Communication, 2003This paper presents an experimental comparison of different algorithms for the gravity compensation of parallel mechanisms, with special reference to a 5DOF haptic interface that has been realized at PERCRO. Two methods for the static balancing of this mechanism have been investigated: a classical method, based on Lagrange's approach and an algorithm ...
