Self-propelled robotic device that moves through bodily and other passageways |
摘要 |
A self-propelled robotic device moves through bodily and other passageways by inflating regions of an overlying bladder along the length of the robotic device in a sequence that imparts motion to the device. The regions of the overlying bladder are inflated by energizing a plurality of coils, which are surrounded by a ferrofluid, in a sequence. The ferrofluid responds to the magnetic field created by an energized coil by creating a bulge in the side wall of the overlying bladder. |
