Meet the Foam Changeshaper Robots

Robots are usually designed with very specific tasks in mind. But the “foambot”, though it looks ungainly, lets you decide on the task and build on the spot.

 

What's the Latest Development?


The Modular Robotics Laboratory at the University of Pennsylvania has created a robot that can be assembled from foam that hardens and pieces that allow the robot to move. The “foambot” looks ungainly, and it is. But once you have a shape, and a task, in mind, the foam sprayer can lay down a body plan that fits. Need  a snake-like bot that can move into small, narrow spaces? No problem. Or arrange the modular parts in another pattern for a more conventional four-legged arrangement.

What's the Big Idea?

A key advantage of this kind of construction is that you don’t need to know what your robot has to do beforehand. This has applications in areas such as space exploration, where building a robot that can crawl, slither or climb allows for exploring an unknown landscape, or rescue operations, where the situation is unknown and it isn’t clear what you need a robot to do (crawl through small spaces or clamber over rubble, or both).

Personal Growth

In truth, so much of what happens to us in life is random – we are pawns at the mercy of Lady Luck. To take ownership of our experiences and exert a feeling of control over our future, we tell stories about ourselves that weave meaning and continuity into our personal identity.

Culture & Religion
  • Steve Munt, Pikachu's owner, created a GoFundMe page to raise money for the mission.
  • If all goes according to plan, Pikachu will be the second cat to enter space, the first being a French feline named Felicette.
  • It might seem frivolous, but the cat-lovers commenting on Munt's GoFundMe page would likely disagree.
