Excuses, excuses...
Anyways, not sure what kind of robot you were planning on using, but this one is cool and reasonably priced. http://anybots.com/ They're located a few miles from Benton, they might actually let you borrow one for Saturday if you asked nicely.
There will be a meetup at 7PM this Saturday at the SIAI house (3755 Benton St, Santa Clara). (More info on the official page.)
The usual set of people will be present, as well as new SIAI Visiting Fellows.
(Sorry for the short notice.)
