I am making a robot that needs to continuously track the relative position of a human, up to 15 meters away and with at least 300 degrees coverage. Currently I am using a Hitechnic IRSeeker v2 sensor and made a beacon wristband with 6 TV remote IR LEDs. But the maximum distance I can get is around 3 meters.
I ordered some 3 watts IR LEDs to boost the power, but the size of the wristband will be a problem because it will not run on a CR2032 battery.
I also bought some IR remote receivers. But I am not sure if the reflection from the wall will give false results.
Is what I am trying to do possible? Is a beacon 15m away feasible using this technology?
- If it is, then what do I need to modify in my current implementation?
- If not, are there any other technologies that I should be considering to track the relative position or direction of human, 15 meters away with at least 300 degrees coverage?
