Abstract: The invention concerns a method for estimating an external force acting on an electrohydrostatic actuator, the actuator comprising a ram including a first chamber, a second chamber and a piston located between the first chamber and the second chamber, a pump capable of injecting fluid into the chambers for controlling a movement of the piston, and an electric motor driving the pump, the method comprising steps of: estimating, by means of at least one state observer (21, 22), a dynamic component and a static component of a difference in equivalent fluid pressure between the first chamber and the second chamber from a rotational speed of the electric motor, a position of the piston and a supply current of the electric motor, estimating the external force by means of a post-processing module (23) as a combination of the estimated dynamic component and static component of the difference in fluid pressure.

Abstract: A system for testing a pressure sensor of a seat includes a loading device and a processor. The loading device removably applies weight to the seat. The processor receives a measurement of a pre-installation pressure offset of a bladder of the pressure sensor measured before installation of the pressure sensing assembly into the seat. The processor is programmed to receive a weighted measurement from the pressure sensor in the seat when the loading device applies weight to the seat and an empty seat measurement from the pressure sensor in the seat when the loading device does not apply weight to the seat. The processor determines a threshold value by subtracting the empty seat measurement from the weighted measurement. The processor determines a seat pressure offset value by subtracting the pre-installation pressure offset value from the threshold value. The processor compares the seat pressure offset value to a selected range.

Abstract: A controlled lean system for a tree feller-buncher includes a sensor configured to measure an orientation of a boom coupled to the tree feller-buncher, and a felling head operably connected to the boom. A controller is operable to detect a cut tree carried by the felling head and to estimate a quantity of tree lean needed to reduce torsional load during rotation of the boom while carrying the cut tree based at least in part on the measured orientation of the boom.

Abstract: A bearing raceway ring (25) disposed near a mounting section (9) is disposed on the outer periphery of a circular cylinder section (19). A fluid-sealed chamber (40) in which a measurement liquid is hermetically enclosed is provided between a first member (8) and the bearing raceway ring (25) which is disposed near the mounting section (9). Pressure acting on the fluid to be measured changes as the bearing raceway ring (25) moves in the cylinder-axis direction, the bearing raceway ring (25) being disposed near the mounting section (9). The fluid-sealed chamber (40) is provided with a pressure sensor (44) capable of detecting a change in the pressure of the fluid to be measured.

The flexible skin may have a shape, absorb fluid, compress in response to force applied to the sponge-like material, and decompress and return to its original shape when the force is removed. The flexible skin may cover an outer surface of the sponge-like material. The fluid pressure sensor may sense changes in pressure in fluid that is within the sponge-like material caused by a force applied to the flexible skin.A robotic system may include a movable robotic arm, a compliant tactile sensor on the movable robotic arm that senses contact between the compliant tactile sensor and an object during movement of the movable robotic arm and that cushions the effect of that contact, and a reflex system that causes the moveable robotic arm to move in response to commands.
