A Polyetheretherketone Six-Axis Force/Torque Sensor

Active Design Method for the Static Characteristics of a Piezoelectric Six-Axis Force/Torque Sensor

To address the bottleneck issues of an elastic-style six-axis force/torque sensor (six-axis force sensor), this work proposes a no-elastic piezoelectric six-axis force sensor. The operating principle of the piezoelectric six-axis force sensor is analyzed, and a structural model is constructed. The static-active design theory of the piezoelectric six-axis force sensor is established, including a...

Error Modeling and Experimental Study of a Flexible Joint 6-UPUR Parallel Six-Axis Force Sensor

By combining a parallel mechanism with integrated flexible joints, a large measurement range and high accuracy sensor is realized. However, the main errors of the sensor involve not only assembly errors, but also deformation errors of its flexible leg. Based on a flexible joint 6-UPUR (a kind of mechanism configuration where U-universal joint, P-prismatic joint, R-revolute joint) parallel six-a...

Six-pack off-axis holography.

We present a new holographic concept, named six-pack holography (6PH), in which we compress six off-axis holograms into a single multiplexed off-axis hologram without loss of magnification or resolution. The multiplexed hologram contains straight off-axis fringes with six different orientations, and can be generated optically or digitally. We show that since the six different complex wavefronts...

Study on Dynamic Characteristics of Six-axis Wrist Force/torque Sensor

It is necessary to detect complex force and torque components of three-dimensional space in research and manufacture, therefore the multi-axis force and torque sensors are developed rapidly. For examples, the six-axis wrist force/torque sensor for robot assembling and automated polishing [1,2], the multi-component strain gauge balance for wind tunnel testing to determine loads on models [3], th...
