Spring 2008.
I designed and built a simple torso for a Go playing(manipulation driven, not strategy) robot for Prof Rod Brooks at MIT CSAIL. Postdoc Eduardo Torres-Jara works on the motor drivers, control, and hand design. Josh Kargas did some of the electronics mounting and routing.

Robot has 6 Series Elastic Actuator degrees of freedom. But waist is locked out and shoulder joints have the spring shorted out.

DOFS:
waist yaw
shoulder x 2
elbow x 2
wrist vertical axis x 1
wrist rotation axis x 1
neck pitch x 1
head tilt x 1
head pan x 1

yes analog sensors. potentiometers are awesome.
