How would one go about sensing a small wooden block's position (1"x1"x1") with a robot (robot dimensions will be less than 1'x1'x1') ? Initially, I was thinking I could use some type of ultrasonic transducer and process its output. However, after reading a few datasheets, it seems that the field of view of an ultrasonic transducer is much bigger than the actual block. This would make it almost useless to try and locate several of these blocks. I am just looking for general ideas on how this could be done or if it is even possible. I can flesh these ideas out later, just looking for a quick brainstorming type of session on these boards.
Thanks.
Thanks.
