Drive circuit for a mode conversion rotary ultrasonic motor

Drive circuit for a mode conversion rotary ultrasonic motor

Annual Conference of Industrial Electronics Society

作者： J. Xu E. Grant A.I. Kingon J.M. Wilson P.D. Franzon Center for Robotics and Intelligent Machines Department of Electrical and Computer Engineering North Carolina State University Raleigh NC USA

A mode conversion rotary ultrasonic motor (USM) has potential applications in miniature robotics. However, its electrical drive circuit presents some unique challenges, particularly in producing a high frequency (/spl sim/40 kHz), high voltage (/spl sim/200 V peak-to-peak) signal into a low impedance (/spl sim/100 /spl Omega/) capacitive motor, while achieving high efficiency. This paper describes the design of such a drive circuit, intended for use with a 12 V battery. The drive circuit consists of a switch-mode power converter driving the USM via a step-up planar transformer. Compensation and resonant elements are added to improve the power efficiency. While the peak efficiency of this circuit is 45%, in practice the equivalent impedance of the USM changes with mechanical load and temperature, resulting in an average efficiency of 16%. The admittance vs. frequency characteristic and the equivalent electrical model for a USM prototype are also presented in this paper. The circuit simulations and loaded testing of a full-bridge DC-AC resonant converter with DC-offset module were performed. A load-adapted frequency tracking method has also been proposed to improve the efficiency and stability of the drive circuit.

Transference of controllers evolved in simulation to real vehicles is an important issue in evolutionary robotics (ER). We have previously evolved autonomous navigation controllers for fixed wing UAV applications using multi-objective genetic programming (GP). Controllers were evolved to locate a radar source, navigate the UAV to the source efficiently using on-board sensor measurements, and circle around the emitter. We successfully tested an evolved UAV controller on a wheeled mobile robot. A passive sonar system on the robot was used in place of the radar sensor, and a speaker emitting a tone was used as the target in place of a radar. Using the evolved navigation controller, the mobile robot moved to the speaker and circled around it. The results from this experiment demonstrate that our evolved controllers are capable of transference to real vehicles. Future research will include testing the best evolved controllers by using them to fly real UAVs. ©2005 IEEE.

IEEE International Symposium on intelligent Control (ISIC)

作者： P.E. Caines M.S. Shaikh Department of Electrical & Computer Engineering and the Center for Intelligent Machines McGill University Montreal QUE Canada

Necessary conditions were obtained by Shaikh and Caines (2002, 2003 and 2004) for hybrid optimal control problems (HOCPs) which resulted in a general hybrid maximum principle (HMP); further, a class of efficient, provably convergent hybrid maximum principle (HMP) algorithms were obtained based upon the HMP. The notion of optimality zones (OZs) (2004) was introduced as a theoretical framework enabling the computation of optimal schedules for HOCPs (i.e., discrete state sequences with the associated switching times and states). This paper presents the algorithm HMPZ which fully integrates the prior computation of the OZs into the HMP algorithms. Adding (i) the computational investment in the construction of the OZs for a given HOCP, and (ii) the complexity of the computation of the optimal schedule, optimal switching time and state sequence, and the optimal continuous control input, yields a complexity estimate for the algorithm (HMPZ) which is linear (i.e., O(L)) in the number of switching times L; this is to be compared with the geometric (i.e. O(|Q| L )) growth of a direct combinatoric search over the set of schedules, where Q denotes the discrete state set of the hybrid system

IEEE International Conference on Mechatronics and Automation

作者： S. Fazli L. Kleeman ARC Centre for Perceptive and Intelligent Machines in Complex Environments Intelligent Robotics Research Centre Department of Electrical and Computer Systems Engineering Monash University VIC Australia

Sensing capabilities of a multi-DSP sonar ring are demonstrated with wall following and obstacle avoidance behaviour. The autonomous mobile robot called "Sombrero" moves perpendicular to the nearest object on the left while controlling the distance to that object and generates high quality sonar maps. The wall following and obstacle avoidance behaviour is very simple due to the accurate and timely range and bearing (incidence angle) information provided by the advanced sonar ring. The advanced sonar ring consists of 48 ultrasonic transducers, 24 acting as transceivers and 24 acting as receivers, seven custom designed DSP echo processor boards and six analogue boards. The sonar ring is able to cover 360 degrees around robot with simultaneously firing of all 24 transmitters. Transmission and echo analysis are performed at repetition rates of about 10 Hz, for ranges up to six metres. Accurate distance and bearing measurements of objects are performed by the DSP system using matched filtering techniques. The robot is able to follow walls of various shapes such as a square, circle, concave corner and convex corner. Sombrero controls its motion based on the range and bearing data captured from the advanced sonar ring every 100 msec while moving with a constant speed. Experimental results illustrate the effectiveness of the sonar ring and the quality of the generated local maps.

IEEE International Conference on robotics and Automation (ICRA)

作者： A. Baghani M.N. Ahmadabadi A. Harati Robotics and AI Lab Control and Intelligent Processing Center of Excellence Department of Electrical and Computer Engineering University of Tehran Iran

This paper is concerned with the derivation of the kinematics model of the University of Tehran-Pole Climbing Robot (UT-PCR). As the first step, an appropriate set of coordinates is selected and used to describe the state of the robot. Nonholonomic constraints imposed by the wheels are then expressed as a set of differential equations. By describing these equations in terms of the state of the robot an underactuated driftless nonlinear control system with affine inputs that governs the motion of the robot is derived. A set of experimental results are also given to show the capability of the UT-PCR in climbing a stepped pole.

The diagnosis of gastrointestinal diseases within the small intestine has been greatly advanced with the introduction of the endoscopic microcapsule in recent years. In an effort to increase its reliability and expand its functionality, a mechanism for stopping and locomoting the capsule within the digestive tract is proposed in this paper. This mechanism, actuated by shape memory alloy wires, utilizes a synthetic microfibrillar adhesive similar to the attachment mechanisms employed by beetles. This fibrillar attachment mechanism is a combination of molecular adhesion caused by van der Waals forces and liquid adhesion caused by capillary forces. The molecular adhesion is enhanced by the presence of microfibers, and the liquid adhesion arises from a secretion from the beetle's footpad. A synthetic version of the beetle's footpad was fabricated from PDMS using a silicon mold. Another version was created from SU-8 using photolithography. Testing revealed decent adhesion with glass and prepared pig intestine in vitro both with a silicone oil to simulate the secretion and without it A prototype robot with simple polymer adhesive pads for stopping successfully attached and detached inside a flexible vinyl tube. An inchworm locomotion mechanism is proposed and is in the preliminary stages of fabrication and testing. ©2005 IEEE.

Learning distributed grasp in presence of redundant agents

Learning distributed grasp in presence of redundant agents

IEEE/ASME (AIM) International Conference on Advanced intelligent Mechatronics

作者： A.H. Elahibakhsh M. Nili Ahmadabadi F. Janabi-Sharifi B. Nadjar Araabi AI & Robotics Laboratory Center of Excellence for Control and Intelligent Processing Department of Electrical and Computer Eng. Institute for Studies on Theoretical Physics and Mathematics University of Tehran Tehran Iran Robotics and Manufacturing Automation Lab Department of Mechanical and Industrial Engineering Ryerson University Toronto ONT Canada

Learning distributed object grasp by a group of robots with redundant members is the main focus of this paper. In Elahibakhsh, A. H., et al. (2004), we tackled the problem of learning form closure grasp for planar convex objects by multiple non-communicating robots without any information about the shape of objects. In this paper, the problem in presence of redundant agents is investigated. Agents' states and actions are designed such that the group learns grasping different objects using Q-learning method. As the environment is not intelligent enough to assess each agent's effect on the team performance, a credit assignment algorithm based on knowledge evaluation is designed. The proposed method considers the environment credit for the team, number of redundant agents, and the expertness level of each agent in its credit assignment. Applicability of the designed approach is verified through a set of simulations. It is shown that the team learns grasping different objects. Therefore, it is expected that the proposed method can be extended for distributed grasp of deformable objects
