This is a couple years old, but seems very cool, from Elephant Robotics:

It’s a two-handed controller exoskeleton that can be paired with robotic arm elements. Watching this has got me thinking: couldn’t I make a low tech version of a wearable two-handed controller that works without any electronics? Like maybe something with some crazy configuration of pulleys, cords, rods, (syringe hydraulics?) etc… hooked up on the other end to a drawing mechanism that can execute the translated movements?
