BB Vision Platform V1 (24 Mar 2007)
Click on image for larger view
This project is inspired by Roborealm’s “Lego NXT Ball Picker”.
The BB Vision Platform Project is different from the Ball Picker (and indeed many other RF-Camera based examples you get in the internet) in one major area; we use USB Web-Cam instead of RF wireless camera and receiver.
So, for those who already owned a USB webcam and is reluctant to spend money on a new RF wireless camera and receiver, this is the solution you're looking for.
In February this year, we did a demonstration of NXT (see SPC above) to MINDS of Microsoft Malaysia and as a token of appreciation, we were given a Creative USB Web-Cam... that's how we got started.
Due to the fact that this is a USB wired camera, the camera has to be hooked up to the USB port on the notebook which runs the Roborealm Vision Software. Hence the entire notebook has to be mounted on the mobile platform itself.
Features:
» Fully Autonomous - will run as long as there is power on the NXt and notebook’s battery
» Vision command and control - using Roborealm’s powerful yet easy to use Video Processor Software
» Tilt-able Video Cam - tilt backwards for an instant view of the back (however, video is up down)
» Sound Sensor - activate your robot by clapping
» Light Sensor - sense bright (day) or dark (night)
» Dual-Ultrasonic Sensors - prevent from bumping into objects on the floor
» Anti-rollover - because the notebook is heavy (and expensive) it has the tendency to flip over especially when stopping
