0:00:00i
0:00:04we are developing software robots and there are three important things to know about these
0:00:10robots
0:00:11first
0:00:12there are made out of soft silicone and they can better than what is because
0:00:16of that
0:00:17there are also inherently safe to be around
0:00:22their partners capability band that's what is these are capable compliant motion and there are
0:00:29also capable of very rapid have john manoeuvres
0:00:33which is the envelope on what machines can do today and at the robot's ourself
0:00:40contains and autonomous
0:00:41in other words
0:00:43we can it's the power source the computation
0:00:46i mean i relation and thanking me for these were asked to deliver their emotions
0:00:51traditionally soft robots have been either self contained
0:00:55for capable of high performance but not able
0:00:59so specifically in our lab we want to achieve both of those goals simultaneously in
0:01:04one machine currently let's talk about has two parts one a little bit smaller is
0:01:10the rigid part which store all the supporting hardware and the second part a little
0:01:14bit larger is the soft body where all the continuous natural movement happens
0:01:19and so we thought about it a fish made sense it has a very similar
0:01:22structure in the head of the fish where the brains are held it's a little
0:01:27bit more rigid
0:01:28but in the rear of the fish where the under that or emotion happens it's
0:01:32quite soft in compliance
0:01:34this is are soft robot fish like we said it has a soft body here
0:01:37in green
0:01:38and the supporting hardware upfront
0:01:41in the way this fish works
0:01:42is its towards fluid onboard in the form of a gas and then release is
0:01:47gas through a series of pipes and valves into the body
0:01:51if you think about it is very similar to balloon up a balloon
0:01:55in that case you're model would be the pressure source in the balloon would be
0:01:59the body actuator and basically by inflating in on inflating different parts the body we
0:02:04can get it actually what's special about this fish is that has its brain some
0:02:08board to
0:02:09so i from my computer tell the fish to move forward a signal was sent
0:02:13wirelessly through the water to the brains and in the brains tell the hardware what
0:02:19to do in order to move forward
0:02:20biological fish use the escape manoeuvre or the cedar to escape rate
0:02:27and the do manoeuvres very screen on the order of a hundred millisecond scale robot
0:02:32fish is also able to execute escape manoeuvre at the same speed on people of
0:02:38a hundred milliseconds
0:02:39the fact that our fish can perform an escape manoeuvres really important for the field
0:02:44of soft robotics
0:02:45it shows that soft robots can be able to self contained incapable of high performance
0:02:50the balloon over so fast and it's got such high body curvature that it shows
0:02:56soft robots might be more capable than heart robots in some tasks
