Robots of the future may be softer, squishier and bendier than robots today. This could make them ideal for space exploration.

It is a wonderful robot, made out of steel and wire — but will future robots look like Perseverance? There is an emerging field of research on "soft robots", where the machines are flexible. These soft robots have many advantages over traditional robots — they're safer, lighter, more flexible and can change their shape and size. NASA is investigating the use of soft robots for space missions. For future visits to Enceladus or Europa, a lander could cut a hole in the ice and then insert a compliant robot through the hole. This robot could then grow and change shape on the other side. References: N. S. Usevitch, Z. M. Hammond, M. Schwager, A. M. Okamura, E. W. Hawkes, S. Follmer, An untethered isoperimetric soft robot.

For more info, please see http://www.physics.usyd.edu.au/~cross In baseball and cricket the best pitchers and bowlers know how to make the ball move due to the effects of aerodynamics. If one side of the ball is rough, the ball swings towards that side because turbulent air 'clings' to that side of the ball and is deflected. Although baseballs and cricketballs appear symmetric, they can be made to fly through the air with a smooth or rough side by judicious angling of the seams combined with the axis of rotation.

On a stream of water you can levitate light balls of all sizes and even disks and cylinders. The mechanism is not the Bernoulli effect... Want to make this at home? https://youtu.be/BppcHF2EdAY My friend Blake from InnoVinci emailed me with a cool idea for a video and footage of levitating balls in water streams. Initially it was tough to explain the physics of what was going on. The standard Bernoulli effect relies on the object being completely immersed in the upward-flowing fluid. But in this case the water seems to form a single stream around the object and it's deflected away and down from the stream. By Newton's third law, the force on the water by the ball is equal and opposite to the force of the water back on the ball, pushing it up into the stream. There is a stable equilibrium position because if the ball moves into the stream, it "cuts off" the water going over the ball so it drifts out. If it drifts out too far, then lots of water passes over the ball, pushing it back into the stream.
