Along with the development of society, the remote control of mobile robot has broad prospect of application. With the continuous development of embedded system, the system provides excellent hardware platform for embedded mobile robot. With embedded KEILUV4 operating system, this paper put forward a kind of remote control method of mobile robots. The experiments had proved the embedded mobile robot has low power consumption and strong real-time control. It also had proved the validity of this method.
The wireless communication technologies are rapidly spreading many new areas, including the automation and the importance of the use of wireless technologies in the data acquisition, building control, monitoring systems and automation of manufacturing processes will grow. Intelligent mobile robots and cooperative multi robotic systems can be very efficient tools to speed up search and research operations in remote areas. Robots are also useful to do jobs in areas and in situations that are hazardous for human. They can go anywhere that is not reachable my humans and can go into gaps and move trough small holes that are impossible for humans and even trained dogs.
Our preliminary aim in this project is to build a Mobile operated ARM7 based robot, which could be able to move in forward backward right and left directions. By using keys on the Mobile. The robot can be moved in all the above specified directions. And the transmission of wireless signals can be carried by using Bluetooth communication.
The robot is fitted with 2 DC geared motors and to control its operation we are using LPC2148 as controller. In this project we are using LPC2148, DC Geared motors, Bluetooth (Tx,/Rx) is used to for the navigation of robot. In this project, L293D H-Bridge is used to drive the geared DC motor.ARM7TDMI is an advanced version of microprocessors and forms the heart of the system. This autonomous robot is used to sense the obstacle and navigate the robot in forward, backward, left, right directions. At the same time the robot will sense the room temperature, and fire. If any fire occurs it sends to the android mobile app.
SOFTWARE AND HARDWARE TOOLS:
- KEILUV4 IDE TOOL
- ISP PROGRAMER
- EMBEDDED C PROGRAMMING
- ARM7TDMI LPC2148
- LCD DISPLAY
- POWER SUPPLY
- TEMPERATURE SENSOR
- FIRE SENSOR
- DRIVER IC
Based on embedded system the application of wireless network connection realized the remote controlling of mobile robot, ensured the software control system, and guaranteed the accurate delivery between different equipment. The experimental results showed that through the application of the embedded equipment, the Android mobile robot energy consumption decreased significantly, and could complete remote operation control functions perfectly.
