Inflatable Robot by iRobot

 

The AIRarm is a robot arm developed by iRobot with funding from DARPA. It is inexpensive as compared with an arm of similar size and lightweight as well. It weighs around 1/10th of the weight of the PackBot 3′s arm. The best part is that it can be easily deflated and kept. A pump is located onboard that allows it to inflated and deflated. Despite its light weight, AIRarm is still pretty stiff once inf, and can lift up to five pounds, or possibly more depending on how much its inflated. By varying the level of inflation, it’s also possible to vary the level of compliance of the arm: this makes the arm a little bit flexible when you need it to be, which in turn makes it safer and more durable. The same construct is used to develop a six legged robot as well.
