ROS Robot Operating System

by Ken Jones

I have designed and built a robotic 1/10 scale radio control car (See link below). I added an Arduino Nano to a HPI Sprint. I have been using Windows based Arduino C code. This package is too limiting. I am considering getting into http://www.ros.org/wiki which is LINUX based. "ROS (Robot Operating System) provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more." Are any of you WLUG members ROS-ites? My Linux skills have degraded due to lack of use (and old age). Here's a pointer to a youtube showing my robocar being a robot and what it is built of. http://www.youtube.com/watch?v=J-rgkt8WDXQ Ken Jones Fitchburg

WLUG BBQ

by E Johnson

Hi everyone, The annual WLUG BBQ is tomorrow! Time & location & contact info has already been posted on the list. We have salad, cheese & crackers, plus a few extra goodies, & the condiments. Dogs, burgers & buns are allegedly arriving. So we expect the event to be enjoyable. A few news items & reminders: 1. We have been fairly bug-free this year, which still seems to be the case. But it is raining now, so, we'll know when we now. 2. Our Driveway is for deliveries (tables/chairs, coolers, etc., but not for Event Parking. There should be adequate parking on Hudson St. If you have a special Parking need, please let me know: iris.gates(a)gmail.com 3. We do not have an icemaker. Whoever is bringing the non-BYOB drinks (the soda), please bring cooler plus ice. If you BYOB, please provide your own cooling technique (cooler & ice) 4. My apt. is on the 3rd floor, so note that the Facilities are a few steps up. 5. Someone has promised to bring a table. That would be greatly useful. Perhaps a second table, even a small card table, would be helpful. 6. BYO lawn chair. 7. Wireless will be on & accessible, but I have not tested it in backyard. 8. If it rains or hails or otherwise becomes inclement, we can adjourn to my apt. Tall people may need a hardhat, but we can cram in. 9. Arts Worcester event is going on in Elm Park lately; there are a few things to see, should anyone wish to take a short walk. Elm Park is only a few steps away. 10. Sign on light pole out front will say WLUG. A Penguin is allegedly arriving, but no clue where he will be located. ## Who is bringing plates, cups, forks & spoons? Could you please check in here before Noon Wed. (my final shopping trip)? TY. See you tomorrow! Liz J
