Mobile robotics is a growing trend in recent years as mobile robots are being used in service as well as industrial sectors. This paper introduces a novel design of a mobile robot platform for use in constrained workplaces. The constrained environments are nothing but congested places, for example hospitals, ware houses, offices, shop floors where various equipments and machineries are to be ar...

This paper introduces a method of design and implementation of a two-wheeled inverted pendulum (TWIP) robot with friction compensation. Friction in the drive mechanism is a critical factor of robot self-balancing and affects its performance. The friction parameters are identified based on the dynamic model of the drive mechanism. The dynamics of the whole robot system are obtained by the Lagran...

AbsIracfAll mobile robots suffer from odometry error. Relative localization from odometry has both the systematic and the non-systematic errors. However, once a precise system error model and its parameters are given, the accuracy of odometry can be remarkably improved. Most previous works on this effort focused on the differential drive robots with little attention to the other types of mobile...

This paper presents recent results from the Robotics Systems Laboratory at the Australian National University in the area of Robot Vision. Progress has been made in the design and construction of novel mechanisms for both active and panoramic vision, together with computer systems that facilitate real-time vision processing. The robot vision systems are being used to develop human-friendly robo...

(FFNN) is used to compensate for the robot dynamics. The FFNN computes the required torques to drive the robot manipulator to achieve desired tracking. The stability of combined PI kinematic and FFNN computed torque is proved by Lyapunov theory. Simulation results are carried out for 3 DOF articulated robot manipulator to evaluate the controller performance.

There are many circumstance limits to human like extreme radioactivity, temperature, chemical toxicity, pressure and so on. But, we need to detect and research region for making our sure safe and state. During long time, human have made a robot that have multi-joint biped robot and mobile robot using wheels. And now, that is developing but it still has some problem that is occurred by condition...

This paper proposes an adaptive dynamic-based path control for a differential drive mobile robot. The control law involves error coordinates expressed in a coordinate frame which are partially linked to the robot. The construction of the controller is based on a two-layer structure using the principle of decomposition of the control problem. Assuming that the robot parameters are unknown but co...

As one of the important branch of mobile robotics, wheel mobile robot has long been paid atten tion to by the research people at home and abroad for its high load ability, positioning accuracy, high efficiency, simple control, etc. Mobile robot has close relation to many technologies suc-h as control theory, computer tech nology, sensor technology, etc. Therefore, research on the mobile robot h...

This paper addresses the position control problem for robot manipulators. We present three new controllers with bounded actions supported by a rigorous stability analysis including the robot dynamics in the closed–loop using Lyapunov’s direct method and the LaSalle’s invariance principle. Besides the theoretical results, the performance of proposed controllers is illustrated by experimental res...

The artificial potential method of constrained robot control is presented. The method does not imply knowledge of a detailed robot model and, nevertheless, makes it possible to drive a robot in the environment with obstacles of any shape and along a desired trajectory as well as to take into account constructive constraints. The method is based on the construction of an artificial potential tha...
