This thesis proposed a method that connecting step motor to image send board which can acquire image to move and remote controlling via streaming image board of PDA(personal digital assistant) based on embedded Linux which is using wireless network There are three embedded Linux system to embody movable image send board. First, though the wireless network a signal of PDA is transmitted to the board which has embedded Linux and a system which is controlled by the expansion I/O port of the board. Second, it's a system streaming realtime image at a PDA which has embedded Linux. The last is a system which controls a process of image board using TCP/IP communication and image send board at PC. These are the system which can use industrial settings and homes. It can also make use of an embodiment method about travelling image robot.

Standard of implementing a robot is Man, so in many field, Many studies are processing to archive a robot, very similar to human being. This paper, based on the theory of man, implemented on the model of parallelism sense and visual information, which is needed when it's moving. Introduced robot uses CCD and designed Image Processing Board for the purpose of archiving vision data. To keep parallel condition, This use ultrasonic sensors for auto-mobile.

RCCL(Robot Control C Library) is general purpose robot control language. It is programmed with C language and composed of C library. So it is well portable and supports sensor integration control and high level force control algorithms. We implemented RCCL on PUMA. We developed servo controller of DDC(Direct Digital Control). We used intel 8097BH one chip micro controller as CPU. One digital servo board controls three motors. Host computer is IBM PC 386DX-33 with RCCL.

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.

In this paper, a direct drive scalar robot manipulator is constructed and its mechanical machanism for operation is explained. Also, a motion controller board for the direct drive robot manipulator was developed where the IBM 486 computer is the main controller. For the developed direct drive robot, a force/motion control algorithm based on an active compliance scheme is developed. A preliminary experiment using the developed direct drive for a peg-in-hole job was done by implementing the control algorithm.

Flow and thermal characteristics of cooling system for the robot controller were numerically as well as experimentally investigated. To obtain the overall flows within controller, the system level solutions were analysed at first and then the board level solutions were pursued to understand the detailed flow and temperature fields near the main board which have a significant influence on the cooling of electronic components. The evaluation for a performance of the heat exchanger was conducted on the basis of the obtained flow and temperature patterns. The results showed that the heat exchanger made a small contribution to the cooling of controller and caused an increase of the temperature in CPU.

In this paper, we develop the on board type image processing system using the CMOS sensor and the RISC type main processor. The main processor transmits YUV 4:2:2 type raw data captured by a CMOS image sensor to another processor(such as motion controller, PC, etc) via serial communication (rs232, SPI, I2C, etc). The role of another processor is line and obstacle detecting in image data received from the image processing board developed in this paper.

This paper presents feedback control?method of educational robot made up of step motor by specific Tiny-C at PPI 8255 board of pocketcom(pocket computer; PC-E200). Machine language capacity of Tiny-C compiler(Ver 1.0) is about 22kbyte, and so it is easily transmitted from personal computer to pocketcom of conventional memory 32 kbyte. This experimental results show that Tiny-C control programs are practised on the pocketcom connected to PPI 8255 board for educational robot and X-Y plotter, and these are presented to show the effectiveness of the proposed algorithm.

In this paper, an Embedded solution for fast navigation and precise positioning of mobile robots by floor features is introduced. Most of navigation systems tend to require high-performance computing unit and high quality sensor data. They can produce high accuracy navigation systems but have limited application due to their high cost. The introduced navigation system is designed to be a low cost solution for a wide range of applications such as toys, mobile service robots and education. The key design idea of the system is a simple localization approach using line features of the floor and delayed localization strategy using topological map. It differs from typical navigation approaches which usually use Simultaneous Localization and Mapping (SLAM) technique with high latency localization. This navigation system is implemented on single board Raspberry Pi B+ computer which has 1.4 GHz processor and Redone mobile robot which has maximum speed of 1.1 m/s.
