IEEE Spectrum wrote up Watch-bot: 

"If you leave the milk out, or forget to turn a monitor off, or leave food in the microwave, the robot will figure out on its own that you forgot to do something and then gently remind you with lasers."

The Watch-bot project is led by graduating PhD student Chenxia Wu; the team includes Cornell's Bart Selman and collaborators Jiemi Zhang, Silvio Savarese, and Ashutosh Saxena
