Let the hive mind of Engadget get that for you.
"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!"
Hello !
I'm from Aldebaran Robotics and i would like to give you more details : Plen is half the size of our robot and it is based on servomotors, which can allow quick moves but not smooth slow moves.
By the way, this is one of the first walk of our robot and we will improve it a lot before the release...Stay tuned !
