Made a few robots so I think I would need/want these sensors at some point,
got a set and to test out and came up with a decent idea?
Hearing impaired rely on their vision for sign language, but blind are limited to a low tech solution.
The current standard is "feel out" obstacles with a stick.
- Proof of concept shows it will work, but the piezo buzzer isn't great.
- I think a servo as on output dial/slide might be the best solution I've thought of so far.
- Downside is music or other interference problems.
- Upside you are notified of objects at a further distance. 0-4 Meters vs 1 Meter.
- I think it makes more sense in an office than outside.
I think it will need more than 2 sensors to get a usable system.
- The lower sensor faces the floor and can detect steps and other changes.
- While the other sensor faces forward.
- Adding a motion sensor may be useful while not walking.
now the piezo will beep if the floor sensor is less than about 1 foot and the forward sensor is 2 feet. The beeps are a different tone and duration changes as distance increases.
Just a basic test sketch for now but catching changes in distance is the main thing needed, pretty easy.
