robot reading a file from disk - serial conversation eavesdropping

by Jake

the robot has an external disk drive which is connected to it with a 25-pin serial cable. The disk drive unit is a computer in itself, with a lot of functionality. It boots up in "ERC MODE" meaning it's ready to talk to the YASNAC ERC, our robot control computer. i spied on the conversation between the robot and the disk drive while the robot loaded a file. I saved the conversation using the salae logic program: https://www.saleae.com/downloads if you run this program you can open the save file i saved: http://spaz.org/~jake/robot/floppy-loadafile.logicdata you will see that the format matches closely that which is described by the communications manual: http://spaz.org/~jake/robot/479236-17-Communications.pdf the baud rate is 4800 baud, 8 data bits, 1 stop bit, EVEN parity. it's connected to the 3d printer computer if you want to write a program to pretend to be a disk drive. then we can send it programs without having to use ancient floppy diskettes. to talk to it from that computer (whose IP address is .42.8) just run a script called "robot" in ~sudodesk/bin/robot it calls screen /dev/ttyS0 4800,parenb,-parodd (that's how you get even parity with screen) when i open that terminal, and then go to the floppy menu from the robot, it sends the following (? means unprintable character): ENQ?ENQ?ENQ?CAN+?CAN+?CAN+?EOT? which means, probably; HEY ARE YOU THERE? HEY ARE YOU THERE? HEY ARE YOU THERE? NEVER MIND. NEVER MIND. NEVER MIND. I'M HANGING UP NOW. see if you can get the robot to load a file from an imaginary disk drive. -jake

Artist as Activist | Robert Rauschenberg Foundation

by Romy＠snowyla

Artist activist grants! http://www.rauschenbergfoundation.org/grants/art-grants/artist-activist Artist as Activist Program Overview Artist as Activist provides game-changing resources to artists (of all disciplines – visual, performing, media, and beyond), designers, and other creative professionals who are addressing important global challenges through their creative practice. In years past this support has included a commissioned print edition to benefit a particular cause or organization. Today the Artist as Activist program is comprised of three distinct grant opportunities: Artist as Activist Fellows: artists and legally established art collectives with a demonstrated commitment to applying their creative work to the public sphere will receive up to $100,000 over two years, along with a suite of value-added support. Fellows will be selected through an open call for proposals. Artist as Activist Travel & Research Grants: a separate pool of funds has been reserved for similar artists seeking support (ranging from $2,500 to $10,000) to travel or conduct research related to this aspect of their work. Travel/Research grantees will be selected through an open call for proposals. Artist as Activist Organizations: Ten organizations from across the U.S. that have been exemplars in supporting artists working at the intersection of art and change will receive general operating support. These organizational grants are by invitation only. Program Values and Beliefs Consistent with our commitment to upholding the legacy of our founder, Robert Rauschenberg, all of RRF’s philanthropy programs operate with a set of core values that embody his work as both an artist and a philanthropist. These values include experimentation, fearlessness, and pushing boundaries. Rauschenberg also sought to learn from other cultures, and to share his own knowledge in exchange for what he learned. The Artist as Activist program retains this approach with a particular focus on: Creative problem-solving and solutions orientation – looking at an issue in new ways that actually shift its paradigm. Interdisciplinary collaboration – experience and enthusiasm for working with people who have a variety of expertise, experience, and training, as well as those whose beliefs, values, and norms differ from your own. Risk-taking – an ability to move outside of the status quo; comfort with uncertainty, improvisation, and/or iteration in the context of continuous learning. How to Apply All eligible applicants are invited to apply for only one of these grant opportunities. Please consult the Apply Now page to review the appropriate Grant Guidelines and Online Application Instructions to prepare your letter of interest. Sent from my iPhone

blog post: troy visits RPS Collective down the street

by Romy Ilano

new blog post > Troy our librarian visited RPS Collective. we chatted about potentially selling our electronics kits + other stuff at RPS Collective retail space. - There's a potential for us to sell stuff at their next art show, which will be a full retail show in the whole space. Lots of potential for exposure since they are the first storefront at First Friday Plus they have collaborated with us before! https://sudoroom.org/sudoroom-connects-with-rock-paper-scissors-down-the-st… [image: SudoRoom Librarian Troy visits SudoRoom]<https://sudoroom.org/wp-content/uploads/2013/11/Photo-Nov-02-1-33-01-PM1.jpg> SudoRoom Librarian Troy visits SudoRoom Troy, the SudoRoom librarian, visits our neighbors The Rock Paper Scissors Collective <http://www.rpscollective.com/>down the street. The RPS Collective was one of the worker’s collectives that helped start the Oakland Art Murmur. Here he checks out the zine library and is already coming up with ideas for different community projects. A recent SudoRoom collaboration involved SudoRoom donating Linux computers to RPS Collective in exchange for a beautiful sign painting. It’s pretty cool seeing the different volunteer-run collectives creating and helping each other out!

Volunteers needed tommorrow (Wednesday) morning!

by yar

Still trying to achieve fire safety & ADA accessibility by Saturday. Lots of things happening tomorrow morning. We need: Someone who can drive a U-haul full of waste to the following places: * hazardous waste * e-waste * recycling * solid waste We can tell you where to go. The truck needs to be returned by 12:30pm. You'll probably need to start by 8am. Someone to help the wheelchair lift installer starting around 9am - simple stuff like holding and fetching tools. And as many people as we can for spare hands during bathroom construction. Thanks so much!!

robot programming format deciphered

by Jake

so I was able to use a primitive magnetic encoding sequencer to read robot programs from a flat magnetic tape. We had some antique (literally 25 years old) diskettes in the computer history museum, and I fed one to the robot, and then "saved" all the programs written so far to the "diskette" then, i used a mechanical diskette-reader for a desktop computer (which needed lubrication on its rusty motors and slides and quite a bit of fiddling to work) to read this magnetic tape "diskette" the filesytem format is nothing recognized by 'mount' so i was forced to simply dd the binary of the diskette's image to a file. I have posted the file here: http://spaz.org/~jake/robot/robofloppy.2 and then i edited that with vim to extract the programs within. here is a simple program that makes 7 poses, and repeats: http://spaz.org/~jake/robot/baby.txt this is a more raw version of all the jobs i found on the disk image, including some fragmentation. I don't understand the filesystem format, so it's just luck that so many of the files were intact in one piece. http://spaz.org/~jake/robot/jobs.txt as you can see, a program is a list of coordinates (the six hardware axes of the robot arm) and then a program referring to those coordinates. it can be more complicated than that of course, for example when we start using base or robot coordinates for 3d printing, but here it is anyway. this stuff is documented in this PDF: http://spaz.org/~jake/robot/479236-17-Communications.pdf and also, i think we might find the serial communications format used by the "diskette drive" to communicate with the robot, so we can skip the magnetic media entirely and send programs directly to the robot over serial. please let me know if you're interested in this stuff and want to try something. -jake

ALL HANDS CALL TODAY/TONITE: HELP LOAD 17' TRUCK WITH OUR DEBRIS

by David Keenan

Hi All. Not much notice but there is a 17' rental truck outside for general omni debris removal. It needs to be loaded up with: - Excess garbage (several bags) - Construction debris from bathroom repair (lots) - Ceiling tiles from ballroom (these are light, so may want to go in last/on top) - Stuff from Sudo that sudo doesn't want (the present 'to go away' piles) - Stuff frrom basement that we don't want/need - All City of Berkeley-stamped grey garbage cans probably should be returned since Waste Management does not pick them up and they fill with garbage. No one is really here and I am starting to do it by myself and would appreciate help. If I do this then I can't work on the bathroom, which needs to be done by Friday. All the waste needs to be driven to the following places tomorrow AM & returned by 12:30pm - Commercial Waste & Recycling by the Colesium (they open real early) - E-waste place (in berkeley I think) for all e-waste - the Oakland Dump tomorrow AM and returned by 12:30. We need to generally remove junk from here that we don't need as this really is required by fire - it can't be a total mess in the basement or any area to be (re)inspected. We have a general mission of clearing out junk from the omni to comply. This was specifically mentioned by the fire inspector - everything should look like its 'in its place' (his words.) Any and all help appreciated. David
