ABSTRACT
Science and technology of robotics originated with the spirit of developing Mechanical systems which would carry out tasks normally described to human beings. An industrial robot is a general-purpose programmable machine possessing certain anthropomorphic characteristics.
Importance of the industrial robot includes the following
- Robots can be substituted for humans in hazardous or uncomfortable work environments.
- A robot performs its work cycle with a consistency and repeatability that cannot be attained by humans.
- Robots can be re-programmed when the production run of the current task is completed; a robot can be reprogrammed and equipped with necessary tooling to perform an altogether different task.
- Robots are controlled by computers and can, therefore, be connected to other computer systems to achieve computer integrated manufacturing.
“A robot is a re-programmable multi-functional manipulator designed to move material, parts, tools or specialized devices, through variable programmed motions for the performance of a variety of tasks”.
This is an autonomous machine with IR proximity sensors on 3 sides. It moves forward by default as soon as it finds any obstacle in front it scans left direction if the left direction is clear it left turn otherwise it scans right direction and goes right and upon finding obstacle on all the sides it goes backward. IR sensor is based on TSOP 1738 with 555 working in astable mode at a frequency of 38Khz. It has a sensing range of 10 to 15 cms. Microcontroller used 8051-AT89C52
Applications:
- Automatic navigation
- Self-running machine
