Wheeled inverted pendulum (WIP) models have been widely used in the field of autonomous robotics and intelligent vehicles. A novel transportation system, WIP-car is proposed in this paper, which is composed of a mobile wheeled inverted pendulum system, a driven chair, an acceleration pedal and a deceleration pedal, which are used to drive the chair forward or backward such that the car can be accelerated...
In this paper, we design a teleoperated mobile Manipulator with 8 joints which includes two-driving wheels and 6 arm joints. The workspace of the studied mobile manipulator is much large than that of a fixed-base one. The goal of the mobile manipulator is to track a desired trajectory of space curves in a fixed reference frame. First, by using redundant joints, the motion capability of the end-effector...
In this paper, adaptive motion/force control by dynamic coupling and output feedback is considered for nonholonomic mobile manipulators with an under-actuated joint, in the presence of parametric and functional uncertainties. It is obvious that the constraints of the system consist of kinematic constraints for the mobile platform and dynamic constraints for the under-actuated joint. Through using...
The balance and motion control based on LS-SVM (least squares support vector machine) are considered for mobile wheeled inverted pendulums (WIP), in the presence of parametric and functional dynamics uncertainties. Based on Lyapunov synthesis, the proposed control mechanisms use the advantage of LS-SVM combined with on-line parameters estimation strategy in order to have an efficient approximation...
In this paper, robust force/motion control strategies are presented for mobile manipulators under both holonomic and nonholonomic constraints in the presence of uncertainties and disturbances. The controls are based on structural knowledge of the dynamics of the robot and the actuator dynamics is also taken into account. The proposed control is robust not only to structured uncertainty such as mass...
Adaptive robust dynamic balance and motion control are considered for mobile wheeled inverted pendulum, in the presence of parametric and functional uncertainties. Based on Lyapunov synthesis, the proposed control mechanisms using physical properties of wheeled inverted pendulums ensure that the outputs of the system track the given bounded reference signals within a small neighborhood of zero, and...
