There was a decent-sized round for Ambi Robotics, which is also using the opportunity to come out of stealth. Founded by UC Berkeley professor (and frequent TC Sessions: Robotics guest) Ken Goldberg, the company announced a $6.1 million seed. The startup specializes in pick and place robotics, starting with a pair of machines: the AmbiSort and AmbiKit. Goldberg has a pretty devoted following in the category, so this will definitely be one to watch.
