"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"

Walking through the CMU robotics lab 10 years ago was truly scary. I can only imagine it now. My friend really had a desire to make deathbots, cute deadly deathbots.
