I spotted an interesting article and tutorial over at Roborealm.com for robotic obstacle avoidance using vision only. For this example they have used a Lego robot base with an Asus EeePC, which shows that you don't need much processing power to do some simple machine vision. Make sure you check out the video of it all in action on page 7.

Roborealm is provided with various interfaces to specific hardware as well as API support and services for Microsoft Robotics Developer Studio. So using the 914 PC Bot MRDS services or C6Jones720's API you could reproduce the example with your 914 PC Bot, or any other hardware platform that supports MRDS.

Don't forget that Roborealm is available as a free unlimited download for personal use.
