I have an installation where a number of 300mm cubes are placed on a play field in any order and potentially stacked on top of each other. I want each cube to have a an arduino inside and report its position and orientation via wi-fi. The play field is an area aprox 1500mm x 1500mm
I'm fairly confident I can use an acceloremeter and gyro to get orientation. Is there a sensor out there that will give me position? If three cubes were stacked on top of each other I want to know the order they are stacked. So I don't need to know absolute position if I know which cubes are next to other cubes. In the past I used a camera but the users get in the way.
Thoughts so far: Some kind of local gps. Not sure if that's possible Near field chips in each surface detect nearby cubes Any other ideas? Any comments about the feasability of these ideas?
