[FRIAM] Dancing Robots

Sat Apr 3 15:07:09 EDT 2021

The last task Raibert mentioned to me before I was promoted and hired by
another school was to develop a standard representation for the
"trajectory" of a robot.  This would have been a set of time series for
each "joint" etc.

I wish I hadn't left but I'm sure that task has been accomplished.
