Well, one way to make the robot always under monitored is using a wireless device (for example normal RF Serial ) to send out "safe" signal to the robot. If the robot can't receive the safe signal, it stops. So somebody who's working with the robot should wear this safety device and keep it on during the work, and if the device is out of a certain range, or somebody pushed the stop button on the device, or the device is out of battery, the robot will stop. That's how willowgarage people deal with their PR2 robot.<br>

The guy controlling it was hacking on some control related system and let the robot operate well outside of a distance that allowed him to see what was going on. I'm not really sure how you fix that sort of problem.<br>

</div>I would actually like to hack with someone on building a little<br>
autonomous shutdown sensor on MC Hawking. I am getting into robotics<br>
again and it seems like a nice self-contained task even for my<br>
notorious project lability (I am one of the several thousand who has<br>
expressed interest with Jake in doing stuff with Noisebridge's Most<br>
Dangerous Robot and then wandered off onto something else).<br>
<br>
I do not mind MC Hawking doing a little random property damage if<br>
pushed, but I would not like him squishing anyone sentient.<br>
