Revision history [back]

I've edited the original question and have determined this isn't a PowerBot specific problem. I've tried implementing this on another platform and have observed the exact same results, which are evidently missed scans. The other platform is simply a laptop running Natty and ROS Diamondback. I used an identical laser to that connected to the PowerBot. I attempted this with two different serial-to-USB converters: FTDI FT232R and Prolific PL2303 both with and without a null modem cable.

In all attempts on both platforms, the results are the same. I'm wondering if this thread should be closed / reopened into a different thread since this is not only an issue with the PowerBot?
