[Noisebridge-discuss] About the missing robotic arm on wheel chair robot

[Hao]

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.
