I"m going to do a machine vision project.
I am working on The vOICe which is a DIY cyborg vision substitution for blind people. It works well, even from the first switch-on, and actually causes reprogramming of the human brain.
The software ( at seeingwithsound.com) has colour discrimination, slow and fast scan, zoom, motion detection, etc. IMHO this could be very useful in a robotic context.
It is Windows and Android hosted, 500KB . Uses USB webcams.
IMHO The vOICe is now sorely hampered by heavy processing equipment, nasty patent camera glasses, general ergonomics belonging to the last century. The R-Pi is the key to making this effective system really fly. Sight-of-a-kind for less than £100.
Would you like to make contact with me to talk about possibilities for cooperation?
