  • Articulated mechanical arm equipped with a passive device for compensation for gravity
    Patent number: 8904900
    Abstract: An articulated mechanical arm includes a passive device designed to compensate for the effects of gravity on at least a first pivot connection which articulates a first member of the arm on a second member of the arm, and constitutes a first degree of freedom of the arm. The passive device includes a drive mechanism and at least one magnetic device. The drive mechanism is designed to transmit to the magnetic device any rotation of the second member relative to the first pivot connection. The magnetic device is designed to produce torque further to the rotation of the second member. The drive mechanism and the magnetic device are also designed such that the torque is retransmitted by the drive mechanism to the first pivot connection, such that the retransmitted torque cancels the moment of force caused by gravity exerted on the articulated mechanical arm, relative to the first pivot connection.
