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