- Lines: 21
-
- We're looking for some ultrasonic (or otherwise) detector to measure
- distances of 5-15 cm to an accuracy of +- 0.5cm or better.
-
- The intended application is to measure the angle (by triangulation)
- of a monopod robot relative to the ground. We have considered
- accelerometers, but the bouncing action of the robot makes them
- innefective. Commercial angle sensors are expensive ($1500) and we
- really only care about a small range of angles (20 degrees), rather
- than the full 180 degrees that most commercial units offer.
-
- So it would be quite easy to measure the distance to the ground from
- a platform atop the robot. All we need is a nice sensor.
-
- Perhaps it is possible to adapt the Polaroid Ultrasonic Kit for use over
- this shorter range, and improve the sensitivity somehow. Anyone have
- any experience?
-
- Any ideas would be greatly appreciated.
