Title: MEASURING DEVICE MADE OF AN OPEN KINEMATIC CHAIN ABLE TO BE TURNED INTO A POSITIONING ROBOT
Abstract:
The invention is relative to a Navigation and positioning system consisting in a measuring system of the relative position between its extremities, having one extremity fixed to the floor, the other suspended in order to compensate the weight, eventually through a system of springs whose tension is controlled by motors and may be measured, in order to allow the arms of which the measuring device is made, to remain in any configuration is placed, balancing the suspended masses and transmitting the forces to the floor, or may be balanced with a clever choice of the constraints. The first condition may be realized for instance, but not exclusively, positioning a torsion spring whose tension is controlled by a motor between two links. On the same arms are mounted brakes that allow both blocking the joint in any position, or driving it directly with the motor bypassing the spring. This way the system may act as a measuring-Navigator not influencing the measure since it does not weights on the operator, but can, on command, turn into a highly precise positioning robot.
