00:03pharmaceuticals are pretty good at helping our bodies get well if we're sick but what if rather
00:07than having a drug go through our digestive tract and possibly cause side effects as it makes its
00:12way to the source of the problem we could deliver it directly well that's what doctors hope to
00:16achieve with this a soft robot they say could go inside your body carrying life-saving treatments
00:21with it the robots body is 3d printed from gelatin but the wild thing is that it doesn't have a
00:26motor
00:26or batteries the whole thing is powered by temperature johns hopkins university professor
00:30and project lead on the inchworm inspired robot david gracias had this to say about it it seems
00:35very simplistic but this is an object moving without batteries without wiring without an external power
00:41source of any kind just on the swelling and shrinking of gel devices like these have been in the works
00:46for years as experts agree that delivering pharmaceuticals directly to tumors blood clots
00:50or infections is the best way to treat them but the robots have to be soft and generally need to
00:54be
00:54able to dissolve inertly within the body afterwards a tall order now the team are looking to train the
00:59robots to travel towards certain biomarkers hoping that soon they will be able to deliver treatment
01:04inside the human body
