Solar Powered Messenger Bag!
Back in university, my final project was an artificially inteligent, powered wheelchair for Multiple Schlorosis sufferers. It used fuzzy logic to filter out hand tremours. It was a moderate success. The project was also to use ultrasonic sensors to resist collisions. That was scrapped due to time and money constraints, and I was not successfull in getting IR to work for the same purpose.
Along comes this device.
Picture this being the filter.
Also, ultrasonic sensors are getting better and cheaper.
Oh well – I guess I’ll have to focus on my other brilliant ideas….
Speaking of brilliant…ha ha, ahem.
Update: This idea has become a reality!
