Re: Slightly off-topic question regarding sonar...
Anything that can affect sound will affect sonar to some extent. The type of clothing and it's thickness will determine the extent. As sound is absorbed by different materials and reflected/refracted by others, the effects will vary as the person moves and rotates in space. The effects are frequency dependent so experimentation with sensors of varying frequency (on different types and thicknesses of clothing) might produce acceptable results.

At every event I've seen this year, there has been at least one robot that left a part on the field. Even some of the robots have decided they don't want to play and this year and made a break for it in autonomous! :yikes: - ctt956 [more]
