We have designed and built a passive haptic display by integrating an electromagnet into an infra-red optical mouse. When the electromagnet is not energized, the mouse acts normally, with the same low friction and only a slight increase in mass. Energizing the electromagnet attracts the mouse towards a ferromagnetic mouse pad, increasing the normal force, and thus the frictional force, between ...
In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...
Since the conventional electro-mechanical converter of 2D valve had problems of step lose due to its small tooth-pitch angle, a novel rotary electromagnet with large tooth-pitch angle and coreless rotor structure was proposed. Combined with the approaches of magnetic circuit analysis, finite element simulation and experimental study, the static and dynamic characteristics of electromagnet inclu...
Electromagnet Weight Reduction in a Magnetic Levitation System for Contactless Delivery Applications
This paper presents an optimum design of a lightweight vehicle levitation electromagnet, which also provides a passive guide force in a magnetic levitation system for contactless delivery applications. The split alignment of C-shaped electromagnets about C-shaped rails has a bad effect on the lateral deviation force, therefore, no-split positioning of electromagnets is better for lateral perfor...
This study addresses the design and testing of a novel soft robotic gripper actuated by an electromagnet with which to handle of unpackaged delicate fruits in the food industry. Traditional rigid mechanical grippers are not applicable to manipulate delicate food products because their gripping action can easily bruise or damage fragile food products during handling due to hard contacts. In addi...
The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape and magnetic field gradient optimization of an electromagnet head. The magnetic field and forces are computed u...
