An Omnidirectional Mobile Millimeters Size Micro-Robot with Novel Duel-Wheels
A millimeters size omni-directional mobile micro-robot is presented in this paper. A unique duel-wheel structure is designed for no-slip motion during the steering, by turning the slip friction between the wheel and ground into rolling friction. The robot was driven by four electromagnetic micromotors with 2.1mm×2.1mm×1.3mm size. Three of them are for translation and the other one is for rotati...
متن کاملEnergy Efficient Drive of an Omnidirectional Mobile Robot with Steerable Omnidirectional Wheels
In this paper the second version of the omnidirectional mobile robot with steerable omnidirectional wheels (OMR-SOW) is presented. This robot can operate in either the omnidirectional or the differential drive mode depending on the drive conditions. In the omnidirectional mode, it has 3 DOFs in motion and 1 DOF in steering which can function as a continuously-variable transmission (CVT). The CV...
متن کاملDesign and Control of an Omnidirectional Mobile Robot with Steerable Omnidirectional Wheels
Applications of wheeled mobile robots have recently extended to service robots for the handicapped or the aged and industrial mobile robots working in various environments. The most popular wheeled mobile robots are equipped with two independent driving wheels. Since these robots possess 2 degrees-of-freedom (DOFs), they can rotate about any point, but cannot perform holonomic motion including ...
متن کاملPath Following and Velocity Optimizing for an Omnidirectional Mobile Robot
In this paper, the path following controller of an omnidirectional mobile robot (OMR) has been extended in such a way that the forward velocity has been optimized and the actuator velocity constraints have been taken into account. Both have been attained through the proposed model predictive control (MPC) framework. The forward velocity has been included into the objective function, while the a...
متن کاملDesign and construction of continuous alternate wheels for an omnidirectional mobile robot
Many types of omnidirectional wheels with passive rollers have gaps between rollers. Since these gaps cause a wheel to make discontinuous contact with the ground, they lead to vertical and/or horizontal vibrations during wheel operation. In addition, the radii of passive rollers are related to the height of a bump an omnidirectional wheel can surmount. In this research a new design of the alter...
