SARA is a robotic arm capable of balancing various objects on itself without dropping them. The mechanism operating it is based on the concept of the “inverted pendulum”: a solution of a classic problem in dynamics and control theory, usually demonstrated by balancing an upturned broomstick on the end of one’s finger. This technology is primarily known to the public from popular products that have integrated it into their systems, such as Segway or hoverboards that automatically balance the person riding them.
Nonetheless, SARA is not just another balancing robot. She is a rather overly sensitive one: using sensors, SARA knows how many viewers are gathering around and reacting to it. As the audience grows, this robot begins to falter, shaking, swaying and even dropping the glasses it is meant to balance. Loud noises affect it in a similar way, making it lose its focus.
