Because its size, it can fit inside any blood vessel and thus can be used to deliver medicine through the bloodstream to any part of the body.

The robots are proposed to be made by biodegradable materials to make sure it is completely safe, before it ventures into clinical trials. If this is a success, it could sure be an idea which could prove to be revolutionary in the field of medicine.
