A framing assembly with lower stiffness design and a method of manufacturing that framing assembly are disclosed. In one embodiment, a framing assembly pattern is cut from a piece of a thin planar material, such as metal. The pattern is then bent to form a framing assembly with a base piece, two arms, and supports for a connection plate. In an alternate embodiment, the base piece includes a rear support and a support base. In a further embodiment, excess material surrounding the pattern is cut away so as to allow the most efficient use of the material.

A compliant gripper with integrated position and force sensors dedicated to automated micro-assembly tasks. The gripper possesses a larger gripping range with a bidirectional drive, and is capable of detecting grasping force and environmental interaction forces in horizontal and vertical axes. The gripper has a compliant rotary flexure bearing. The gripper further has a compliant mechanism with two-stage stiffness designed to provide force sensing with dual sensitivities in two measuring ranges to accommodate the grasping of objects with different sizes. The dual-sensitivity, dual-range force sensor provides finer and coarser force sensing in a small and large ranges, respectively. Analytical models are derived to predict the grasping range, force sensing sensitivities, and force measuring ranges. These models are verified by conducting finite-element analysis simulations.

The invention provides a coupler for a shaft suspending type installing direct drive motor. The coupler comprises an axle side connecting disc fixed coaxially with an axle, and a motor side connectingdisc fixed coaxially with a motor rotor shaft. The coupler is characterized by further comprising an elastic supporting rotating assembly. The elastic supporting rotating assembly is connected between the axle side connecting disc and the motor side connecting disc, thus the axle side connecting disc and the motor side connecting disc are coaxially connected in a rotating manner, the elastic supporting rotating assembly bears the motor weight in the radial direction, and the axle side connecting disc and the motor side connecting disc are elastically connected in the peripheral direction. According to the coupler, while the requirement for large radial load is met, the better vibration reducing and buffering effect can be obtained, the failure risk is reduced, the service life of a metalrubber part is prolonged, the use reliability of the coupler is improved, centering connection between the axle side connecting disc and the motor side connecting disc can be achieved easily, the installing reliability and convenience of the coupler are improved, the installing process is convenient and easy, and overhauling and replacing are facilitated. The invention further provides a rigiditydesign method of the coupler for the shaft suspending type installing direct drive motor.
