Gravity Compensation and Crown Gall Development
Nature, 1969CLINOSTATS provide a means for ground based studies of what happens when plants are subjected to null-gravity conditions1. The incubation period of leaf rust on gravity-compensated bean plants is shorter than on non-compensated controls2. Here we describe the influence of gravity compensation on crown gall development in the carrot (Daucus carota).

Gravity Disturbance Compensation for Inertial Navigation System
IEEE Transactions on Instrumentation and Measurement, 2019This paper investigates the gravity disturbance compensation for inertial navigation system based on high-resolution global gravity field models. The high-precision gravity is calculated using the European Improved Gravity model of the Earth by New techniques (EIGEN)-6C4, which is a representative of the high-resolution models.

Prismatic Gravity Compensator for Variable Payloads
IEEE Robotics and Automation Letters, 2022Gravity compensators are passive devices that can lower the energy consumption of lifting systems by reducing the force/torque required from human users or actuators. This paper presents a prismatic gravity compensator for cranes, gantry, and other lifting systems.

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 ...

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 ...

Gravity Compensation Walker: Structure and Safety
Volume 5: Biomedical and Biotechnology, 2020Abstract Morbid obesity is a widespread problem in the united states. The rate of falls and injures is much higher for obese individuals when compared to individuals of normative weight. Obesity can also impose excessive load to the hip and knee joints during the sit-to stand transition, which is conducive to osteoarthritis and increased
