Robot Tele operation System Based on GPRS
Synopsis:
Robotics has now converged with mobile communications, making alternative interaction with these devices possible, such as the tele operation of robots using cell phones. This subject has been studied for many years now, and the advantages and limitations of technological integration has been analyzed. For example there are difficulties with communication links, and there exist latency effects in real time communications. Also, the potential applications for these types of technologies, such as home robots, have been investigated. Home robots are designed not only to monitor houses and people, but also to perform domestic chores in a semi-autonomous way; and can be programmed or reprogrammed from distant locations by means of a cell phone. Applications using robots to help disabled or mentally challenged people with special needs have been explored. In this case, a mobile communication system increases the robot’s performance and ease of operation. Despite the limitations, there are many possible applications for cell phone tele operated systems.
Problem statement:
• Distance between monitoring and robotic unit are limited
• Monitoring through manually
• Home robots are designed only to monitor houses and people
• Remote monitoring and control are impossible
• High power consumption
Proposed system:
In this paper we present a strategy for using the cellular network, and specifically the general Packet Radio Service, to teleoperate a mobile robot. This allows the system user a wider mobility range and coverage. The system application is developed using Java Programming Language, implementing two teleoperation methods: predefined sequences and instant actions.
Remote automation and monitoring devices have been implemented along with the developments in internet connectivity and, more recently, internet connectivity has been incorporated in the cellular network; in particular by means of data services such as CSD and GPRS. These systems offer advantages in terms of range, velocity, mobility and ease of use for the end user. With the development of generations of cellular technology and their application to remote automation and monitoring projects, it has been possible to develop a large number of applications from alarms, security systems, vehicle and vending machines monitoring, electronic boards and luminous panels, to telemedicine.
This paper describes a Robot Application System developed using mobile communications and integrating data transfer technologies. The system was developed to tele operate a robot such as the Giraa_02, a robot initially made for robotic research only. The application runs on a cell phone, implementing the following two control methods: The first consists of real time commands sent by the user via the application interface, while the second consists of sending preprogrammed sequences to a dedicated server, which then sends the orders to the robot sequentially using predefined timers.
Software Tools:
• Keil C compiler
• Orcad Tool for Circuit Design
• Embedded C Programming Language, Java
Hardware tools:
• ATMEL 89S51 controller
• RF transmitter/receiver
• Encoder/decoder
Applications:
1. Industrial application
2. Robots to help disabled or mentally challenged people
3. Alarms, security systems
4. vehicle and vending machines monitoring
