These measurement robots will work tirelessly for days at a time, and the data they provide about the world can offer young people a way to broaden their notions about the observable universe. The mBot is too large to be worn around a person’s wrist, but the process for designing an environmental sensor for the mBot has much in common with developing technology that goes into wearable commercial tech products like smartwatches.

Probes and sensors have been a standard part of science classrooms for decades. Vernier manufactures dozens of different ...
