It’s not difficult to envision robots that might be among us. After all, some already do: drones and autonomous cars.
But take this to a nano scale, and it begins to sound creepy. For instance nano-bots have been envisioned to seek and destroy cancer cells in our bodies. (A nano meter is one billionths of a meter.)
On a slightly larger scale are robots that could look like insects or other critters, and work together as a swarm –a project that a friend at Arizona State University is currently working on. These bio-inspired robots could have many applications.
So the smaller they get, and the smarter they build them, we could expect to see them be among us. What this means for students is that there will be a huge demand for those who understand, investigate and have a mindset ready to work on these curious ‘machines.’
Science and STEM teachers often bring up robotics as a way to open up this topic to young students. Most of us use bots with wheels, arms and sensors. It’s time to think small!
