A mathematical model of static for a parallel mechanism is generally established by using the force Jacobin matrix [1], [2], [3], which is inaccurate due to ignoring of self-gravity of the linkage [4], [5]. In this paper, based on taking self-gravity of the linkage into account, static analysis of a novel 3-DOF parallel mechanism with RUU joint structure that can perform three-dimensional translations is put forward. Based on the inverse-kinematics of parallel mechanism and forces (torques) transfer mechanism between different hinges, static model is established in order to improve accuracy of static model. Then, a numerical example is given. © 2012 IEEE.

Force modeling for tooth preparation in a dental training system

Virtual Reality 2008年第3期12卷 125-136页

作者： Liu, Guanyang Zhang, Yuru Townsend, William T. State Key Lab. of Virtual Reality Technology and System Beihang University Beijing China Robotics Institute School of Mechanical Engineering and Automation Beihang University Beijing China Barrett Technology Inc. Boston MA United States

Feedback force is very important for novices to simulate tooth preparation by using the haptic interaction system (dental training system) in a virtual environment. In the process of haptic simulation, the fidelity of generated forces by a haptic device decides whether the simulation is successful. A force model computes feedback force, and we present an analytical force model to compute the force between a tooth and a dental pin during tooth preparation. The force between a tooth and a dental pin is modeled in two parts: (1) force to resist human's operation and (2) friction to resist the rotation of the dental engine. The force to resist the human's operation is divided into three parts in the coordinates that are constructed on the bottom center of the dental pin. In addition, we also consider the effects of dental-pin type, tooth stiffness, and contact geometry in the force model. To determine the parameters of the force model, we construct a measuring system by using machine vision and a force/torque sensor to track the human's operations and measure the forces between the dental pins and teeth. Based on the measuring results, we construct the relation between the force and the human's operation. The force model is implemented in the prototype of a dental training system that uses the Phantom as the haptic interface. Dentists performing virtual operations have confirmed the fidelity of feedback force. © Springer-Verlag London Limited 2008.

A novel velocity sensor based on electromagnetic induction was proposed in this paper. It was composed of four small inductor chips with circular symmetrical distribution on the bottom of a printed circuit board (PCB) and an elastic body with a permanent magnet embedded into on the top of the PCB. The output voltage of each inductor chip will change when an object moves on the top of sensor and drives the permanent to follow with a specific speed. The principle of velocity measurement was derived and simulation was carried out to determine size of the magnet and size of the whole sensor. Then, a prototype was developed and velocity experiments were executed to evaluate properties of the prototype. The result shows that the prototype was capable of following the velocity curve of a motion platform and measuring the velocity vector of the platform with nonlinear errors of 8.1% and 11.9% along its x-axis and y-axis respectively when the speed was from 1mm/s to 9mm/s. © 2011 IEEE.

The lunar surface is a complicated and unknown terrain, and hence, astronauts must be trained to travel on that surface by using a prototype vehicle on the Earth's terrain. However, the gravity of the Earth is six times that of the Moon;thus, the acceleration of a prototype vehicle on the Earth will differ from that of a manned lunar rover on the Moon, when the same acceleration handling input is provided. To obtain the same acceleration in the prototype vehicle on the Earth as that obtained on the Moon, an imitation handling ratio describing the relationship between the acceleration handling input and the wheel rolling speed is proposed in order to replicate the lunar gravitational conditions on the Earth. First, a whole-vehicle acceleration model was established based on the mechanical model of a deformable wheel with a mesh surface. Thereby an acceleration imitation algorithm was derived. A prototype vehicle for use on the Earth is proposed for the purpose of imitating the manned lunar rover under four different vehicle conditions. Fitted functions were used in order to obtain the imitation handling ratio. Finally, experiments were conducted to verify the imitation method;the results revealed that the prototype vehicle on the Earth could effectively approximate the same accelerations experienced by a manned lunar rover, when equivalent acceleration handling inputs were provided. © 1967-2012 IEEE.

This paper presents a four-legged bionic robot based on leg reorganization with the hunter spider as the bionic research object. By studying the biological structure of the hunter spider, its movement mode, and the characteristics of limb movement during the conversion process is analyzed and the principle of wheel and foot conversion of the robot is obtained. The three-dimensional model of the bionic robot is designed, and the overall assembly of the bionic structure model is completed. The rationality of the design of the bionic structure is initially verified by the leg reorganization. The virtual prototype is built by adding constraints to realize the bionic motion simulation, including in-situ rotary motion, foot-wheel conversion motion, wheel motion, wheel-foot conversion motion, foot motion, which provides a theoretical basis for the development of the physical prototype and the selection of hardware. © 2021 IEEE.

Standing wave acoustic levitation transportation technique has been widely used in many research areas. In this work, two Langevin-type piezoelectric transducers' central lines are mounted at a certain angle which is named a contraposition transducer array. The levitator developed in this work is constructed using the array and a reflector. Accordingly, a standing wave acoustic field is formed to levitate and transport particles by optimizing the angle between central lines of the two transducers, the distance between the two transducers' output and their reflectors, the exciting phase differential on the two transducers. In this standing wave acoustic field, the trapped objects can be levitated and transported by modulating the exciting phase difference of the two transducers. In this work, the locations of the levitated particles are acquired by a high speed video camera and are clarified using the Hough Circle algorithm. The experiments carried out by the authors have demonstrated the effects of the levitator's structure parameters (including the angle between central lines of the two transducers, the distance between the two transducers' output and the reflector) on the transportation trajectory. © 2020 Acoustical Society of America.

Although robot assisted minimally invasive surgery brings the gospel to patients, force perception is gone. Among all the contact forces during surgery, the instrument grip force plays the most important role. In this paper, a grip force perception method based on denoising AutoEncoder Neural Network (dAENN) is proposed. The method utilizes sensor data including encoder readings and motor current over a time window as the input of dAENN for sufficient information. An Artificial Neural Network (ANN) is then introduced as a machine learning tool to learn the nonlinear mapping between the compact features and grip force labels. Feature extraction is first introduced into grip force perception problem in this paper. Experiment results shows adequate expressive capability of the extracted coding as well as the superior grip force perception performance over several popular data-based methods under the same dataset. © 2019 IEEE.

Pervasive computing, with its focus on users, has the potential to fundamentally change the way people use computers, which challenges the traditional human-machine interaction mode and requires more natural interactive mode between human and computers. The requirement for natural speech in pervasive computing environment was discussed. And a speech interaction system was designed and implemented to meet the requirement of human-machine interaction for an intelligent office system in pervasive computing environment, and a practical solution was given. By this solution, transmit and convert of speech between the server and the embedded handheld device were fulfilled. Speech middleware of the system can provide friendly human-machine interface for the intelligent office system, and the key method for speech synthesis in different operating systems was provided and implemented in the system. © 2006 IEEE.
