Estimate the Pulling Force of Boston Dynamics' Robo-Dog Army

When Boston Dynamics shares a new robot video, my robophobia levels increase just a little bit. There is something about these robots that get into the uncanny valley for me. This particular video is both fascinating and disturbing. It's fascinating because here are a bunch of robots pulling a truck (not a pickup truck--a real truck). It's disturbing because it shows a BUNCH of robots.
