Your boss tells you to deliver a package from your building’s first floor up to the fifth floor. You pick up the package from the receptionist, and to save time, take the elevator. You then press a button to call the elevator, squeeze in with other riders, push the fifth floor button, and hand the package over in no time. But would this be as easy if you were a robot?
“Courier robots” that securely and inexpensively deliver parcels are gaining popularity. Elevators are much safer than stairs, but some tasks involved in using an elevator that are easy for most people can be challenging for a robot.
I was sitting in my college dorm room, working on some engineering homework, but I just couldn’t focus. My mind kept wandering back to the game. How could I have played so poorly? My teammates must hate me. Did I cost us a chance at the playoffs?
In college I played on the varsity baseball team and studied mechanical engineering. I worked hard on the practice team for 2 years and finally got my shot to start at third base as a junior. But things weren’t going according to plan. Third base has a long throw across the infield to first base, and I was having trouble making the throw accurately. By itself, this wasn’t unusual; every player goes through his funks and eventually works out of it. But despite hours of extra practice, I was stuck in a rut. My frustration culminated in a game in which I committed 4 throwing errors and we lost to an important division opponent by 1 run. My teammates had battled tooth and nail to make it a close game, and I literally threw it all away.
