Programmable robots have immense potential in transforming the way daily routines are performed. Interaction with our surroundings can be greatly enhanced by deploying these robots. We have developed a dynamic way of programming a robot that traverses a fed input path. A scaling mechanism that can map a large room onto the user’s held hand device has been introduced. An intuitive way of measuring the speed and position of the robot using basic IR sensors is also devised. In a nutshell, robot is aware of its speed, position and is flexible to travel in any path specified by the user in real time. Applications are far flung and the robot could potentially aid the semi-autonomous navigation of vehicles. Results of the proposed methodology could lay foundation for building a robot with abilities rather than tasks. It could change the way the robots are conceived and utilized.

8. State of the Robot
State = (x , y , z )
(x , y)  Cartesian coordinates of the location of the robot
z indicates the direction of the face of the robot
Z=1Z=2Z=3Z=4Z=5Z=6Z=7Z=8
Robot base
Direction of robot’s face
