Close... but more like this:
Thats not the "evil one".
The Evil one was 4 hub motors on 10" custom machined omni-directional wheels running 60V autonomous/remote control
We chased Astro Teller out of the lab with it- literally.
The machine would move in the most creepy way... it could swing and pivot and had no preference forward, sideways..
(Hard to describe in words - no longer have the videos)
Suffice to say... it was a terrifying implementation of what future security robotics could end up being.
No escape if one gets after you.
Justin was hesitant to support our project
We gave him assurances that we would "kill it" if it got out of control.
(All the robots had a remote kill which required physical human boot-strapping to bring back up. Rule #1 to autonomous beings)
Increasing battery voltage and controller current limit will result in a non linear experience
