Remote RC5 Protocol Controlled Pick and Place Robot.

An embedded system is a special-purpose computer system designed to perform a dedicated function. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few pre-defined tasks, usually with very specific requirements. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product.
As the technology develops, security becomes a major concern. The security not only means securing the important things but also the data’s. Using simple home appliances for this security purpose will be very much useful to solve the problem.

Proposed System:
As the name implies “Remote RC5 Protocol Controlled Pick and Place Robot.” we use a simple TV remote as a door opener. We, here use a low cost 8-bit microcontroller and a pre-defined key which is burnt in the microcontroller. In the receiver section we use an IR receiver attached to the controller. The controller checks the output of IR receiver and compares it with pre stored key. If it matches, the controller switches on the relay and in turn controls the robot movement through a motor connected to it. Here we just use a display unit to find the values returned by the remote for each button. We are going to check the obstacles using IR sensors and we are going to switch different keys in the remote to vary the picking and placing operations.
