Check out this FPGA project that uses a camera module and laser to do obstacle and cliff detection. It’s Wishbone compatible so we should be easily able to import this project into DesignLab.
Somewhere down the road, you’ll find that your almighty autonomous robot chassis is going to need some sensor feedback. Otherwise, that next small step down the road may end with a blind leap off the coffee table. The first low-cost sensors we might throw at this problem would be sonars or IR rangefinders, but there’s a problem: those sensors only really provide distance data back from the pinpoint view directly ahead of them.
