Howdy from San Antonio, TX
Your pic caught my eye as our team had initially looked at a pantagraph type mechanism for the arm verses using chain and sprockets on the shaft. We just couldn't concive a good drive mechanism. It appears that you used two lead screw drives. Is this basically threaded rod, or is it actual gear stock threads? I would be very interested to view close-ups of the mechanisms. Do you have more posted on a team wesite

If not send me some .jpg, my email system should be able to handle two or three attachments per message.
I also like the sloped sides of your 'bot to help defend against pushbots. Do you have documented evidence from game film showing their effectiveness?
Thanks a bunch,
APS
