I am making a robot that needs to continuously track the relative position of 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 there any better solution to track the relative position or direction of human, 15 meters away and at least 300 degrees coverage?

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?
