I am working on a robot that detects a particular object upto 2-3m, and follows it.For this i need 'long range transmitter circuit and receiving sensors', be it ir or anything.
Where can I get such stuff from?
I am a newbie in robot-making and robotics india.Its the only forum where i can expect my queries to be answered by someone..
