2002 Motion planning for humanoid robots using timed Petri net and modular state net
abstract
We propose a supervisory control system for motion planning of humanoid robots. The proposed system is hierarchically structured into two levels. The lower level controls and monitors the robots using modular state nets. The upper level generates an optimal sequence of motion for user's requirements using timed Petri nets.

2001 LLP supervisory control with timed Petri net models in mobile robots
abstract
This paper deals with the high level control of robot systems. We abstract the robot system as timed Petri net and give a high level controller which consists of a limited lookahead policy (LLP) supervisor. A simple application of the control system to a mobile robot system is given.

2000 Design of a Desirable Trajectory and Convergent Control for 3-D.O.F. Manipulator with a Nonholonomic Constraint
abstract
This paper deals with the control of a 3-link planar underactuated manipulator whose most distal joint is unactuated. This system is known as a second order nonholonomic system. In a previous paper (1996), we proposed a control law that guarantees the convergence of its state to a given desirable trajectory and to any desired final point, and we also gave a design method of the desirable trajectory. However, this method has a limitation on the location of the initial state. In this paper, we propose a design method of a desirable trajectory that starts from any given initial point, converges to any given desired final point, and on the way passes through any given desired passing point that can be specified rather freely. By this new design method, one can derive a desirable trajectory that satisfies given requirements much better than the previous method.

2000 Controllability of under-actuated planar manipulators with one unactuated joint
abstract
This paper is concerned with the analysis of controllability for a class of nonholonomic systems. We discuss the controllability of under-actuated planar manipulators with one unactuated joint. We show that these systems are completely controllable if the first joint (in the base side) is actuated. In order to prove this, we use a kind of bi-directional approach.

2000 An application of LLP supervisory control with Petri net models in mobile robots
abstract
This paper is concerned with high level control of robot systems. We abstract the robot system as a discrete event system and present a high level controller which consists of a limited lookahead policy (LLP) supervisor and a Petri nets model. We show its simple application to a mobile robot system.
