Want to build your own Baymax? Soft robotics may not be quite ready for health-care robots, but research at iRobot, Otherlab, MIT, Harvard, and Carnegie Mellon is surging ahead. Get started on your own with these three techniques from Carnegie Mellon’s Chris Atkeson, and find many more tips, tricks, and resources on his page at

  1. Enclose air in sheets of sewn, sealed, material, structured like clothes. One way to experiment is to buy cheap inflatables — or scavenge broken ones — and use the repair kits, a hot air welder, or an impulse sealer to make the seams.

  2. Use 3D design and printing (or machining or cutting) to make more complicated shapes. Working directly with flexible materials can be challenging, but that’s only one approach — you can use these techniques to create molds for other materials.

  3. Carve, sculpt, dip, spray, or mold a soft material, such as silicone. The result won’t be as obviously inflatable as Baymax, but you can equip it with internal bladders and space for actuators, sensors, bat-teries, and more.

  1. what about using smart fibers underneath this material? Could you not develop a thread that when electrically stimulated led to certain shapes or forms as an outcome?
