The design of a control language of mobile robot system for autonomous operations is explained in this paper. The on-board controller consists of one-chip microcontrollerbased system and communicates with the host computer. It decodes the received commands and controls the mobile robot. The control language is basically of interpreter type and is consisted of motion primitives and sensing primitives. The combinations of primitives are constructed for mobile robot operations.

This paper represents the control software development for Direct Drive Arm Robot with the WHILE language composed the 68000 assembly language and high level language modula-2. Direct Drive Ann Robot needs the control program which is fast step and exactly position moving because Direct Drive Arm Robt depends on accuracy. We found that the self-tuning algorithm for this robot control is very good for the real time control and the floating point operation using the 32 bit CPU(MC 68020) controller.

A simple look and move type navigation algorithm with obstacle avoidance was implemented on a mobile robot equipped with two cameras. The robot gets a difference of two images from each camera and detects the position represented on the horizontal line and width of each obstacle in a certain distance. The obtained informations of obstacles are used to select a next intermediate point and to plan a path to it. Robot motion is simplified to straight line motion and rotation.

A walking robot must have the ability to change the body direction in order to avoid the obstacles. In this paper, we develop a gait control algorithm that can maintain the stable movement of the robot for three different modes of changing directions. The algorithm makes it possible for the robot to have the larger gait stability margin than the threshold value by the method of changing the body speed.

In this paper, a programming system for robot-based manufacturing cell which can control and simulate manufacturing devices as well as robots in workcell is proposed and developed. The system is based on world model, and modem textual and object-level robot programming language and interactive graphic world modeler are used to construct and exploit world model. Graphic simulation is used as an efficient and easy to use debugging or verifying tool for user written robot programs. Machine dependency is minimized by adopting the hierarchical control structure and by assuming all the workcell components as virtual ones.

This paper deals with the solution of inverse kinematics of the industrial FANUC robot with IBM PC386. The inverse kinematics of FANUC robot cannot be solved by the algebraical method, because arm matirix T$_{6}$ is very complex and 6-joint angles are associated with the position and the approach of end-effector. Instead we fuund otehr 5-joint angle by and algebraical method after finding .THETA.$_{1}$ value by a numerical method.d.

This paper deals with a dual mode control system design for the starching work robot. From the feature of this work, the robot has redundant degree of freedom. In this paper, we try to split the whole movement the robot into a gross motion part ai. a fine motion part so as to achieve a good tracking performance. The preview learning control is applied to the gross motion part. The validity of the dual mode control architecture is demonstrated.

The closed loop robots have the advantage of higher velocity capability and often higher precision in comparison to the open loop robots. We have simulated the kinematic analysis of three limbs robot (T-L robot), which is one of the closed loop robots. After then, we have designed experimental T-L robots with 3 different kind of actuators. In this paper, we described the experimental results, and the problems in its applicatons.

This paper describes a design of the dynamic robot arm controller with two points of view, robustness and minimum tracking error. A new approach to the robust control of robot arm is developed and an explicit solution for minimum tracking error control is obtained from the regulator problem in the error space given by modifying the tracking problem. This control law is applied to the SCARA robot and the computer simulation is presented.

A software package CARDS for general purpose robot design, control, and simulation has been developed and is presented here. CARDS (Computer Aided Robot Design and Simulation) consists of a collection of standardized subroutine modules that carry out typical kineamatic, dynamic, and control computations so that the user only needs to write a main program that further defines a particular robot configuration and the task to be performed. It provides users a complete simulation environment, so that it will be a valuable engineering tool for mechanical designers as well as electric control designers.
