A group of scientists have begun the work to minimize the procedure’s discomfort by creating a digestible snake-like robot that would move itself through the digestive system.
SAW is unlike most moving devices due to its dynamic movement. While most bots have wheels or legs to move, SAW moves using the wave-like motion of its body. This is possible, in part, due to the SAW’s calculate actuator travel life that enables it to move by pushing the area around it. Like a snake that slithers and writhes its body forward, SAW rotates its helix-like shape in a single direction that allows for movement through many interesting terrains.
