An arboreal robot with powersaws.

The picture doesn't really do it justice.
It's a robotic arm with a complicated wrist at each end with a grab and a saw on each wrist.
Weird watching it in action it grabs one tree, then swings around with the other end to cut down another tree. Grabs a new tree, cuts down the one it was originally holding.
My search roll failed so that was the best link I could find.
I did find a good clip of a hexapod logging robot in action though.
