Hi there!
We are building a robot at my university, as a part of a competition. One of the features it has to have is that, it should be able to detect black drums, as it passes by. So the robot will keep moving on its wheels, and when it detects a black drum (at about 10 cm on one side), it should stop and do something on it.
Our first obvious choice was to use a IR transmitter/detector circuit. But this isnt very straightforward, as black objects absorb IR, rather than reflecting it.
I would be glad if someone can tell me how this could be accomplished, and the circuit which we would require. This would help us 'greatly'.
Now our total budget for the robot is 150 dollars (it is the rule). So any pricey component wont do. So at max, we can afford a sensor which is 20 dollars (we need two of these, one is for detecting the drum's height, which is another task)
Thanks!
