East Bay Mini Maker Faire Oct. 19 [was Fwd: Alert! Call for Makers Extended through 9/15]

by Patrik D'haeseleer

Any other groups planning to attend East Bay Mini Maker Faire? I'm planning to register for a booth for CCL. We can ask to be next to each other if we have multiple groups from the Omni participating... I've attended the East Bay Mini Maker Faire since they started 3 (4?) years ago. It has a much more local, intimate, and less commercial feel than the giant San Mateo one. Tons more kids and families as well. Not to mention that it's essentially within walking distance... After party at the Omni? http://ebmakerfaire.wordpress.com/ http://ebmakerfaire.wordpress.com/callformakers/ Patrik ---------- Forwarded message ---------- From: East Bay Mini Maker Faire <info(a)ebmakerfaire.com> Date: Wed, Sep 10, 2014 at 10:43 AM Subject: Alert!

robot limitations and hacking

by Jake

My friend Hao of Dorabot wrote me an email that clarifies what we can expect from the robot. Of course this assumes no hacking, and we can hack. one thing I was interested in was "remote" mode through the serial port. I believe that it can be set to be controlled by commands like "let me send you this job" "start that job" which would allow us to effectively control it in real time. but that will take some reading of manuals and experimenting. As for the latter, i have connected the robot's serial port to the desktop computer we use for 3d printing, and I can provide logins for that machine to anyone who wants to experiment. I confirmed that with the null-modem adaptor (thanks Somebody!) it does communicate, although i haven't had any meaningful conversations with it. of course there is always the radical alternative - the entire YASNAC control system could be replaced with a homebrew solution that allows us to do whatever we want. The problem is that it would take a bit of programming to drive the axes at speed without overshoot, and there's dynamic gravity and inertia dependant on the posture of the thing and the mass of whatever it's holding.. could be a lot of math to get it perfect. however, if someone were to create a control program for it, a lot of people around the world might like to use it. Hell, people would probably pay for it since it would easily replace an entire YASNAC ERC unit. the motor controllers we have are the CACR series as described here: http://spaz.org/~jake/robot/CACR-SR-servopinouts.pdf and they are pretty simple to control - you send them an analog voltage to tell them which direction to turn, and how fast. You send an analog voltage to say how much torque to exert (seperately for each direction), and it sends out analog voltages telling you how fast it is going, and how much torque it's exerting. And of course the encoders are always telling you the actual position for all the axes so you can decide whether to make changes to get what you want. in the meantime though, we should keep playing with it as-is and see if we can "hack" to get control of it without anything as radical as a replacement controller. -jake ---------- Forwarded message ---------- There are several models of MOTOMAN robot that can be controlled over serial port, and some even supported by ROS Industrial community. If your Robot controller is DX100, then you are very lucky. However I think your robot is super old so probably not supported by ROS Industrial. You can check it out here: http://wiki.ros.org/Industrial/supported_hardware Anyway, usually an industrial robot can be used in following ways: Teach & Replay by teach panel offline programming (generate a tool path offline and upload it, like 3D printer) modern robot can be used in these ways, in addition to previous ones: online program uploading (you generate end-effector/tool path and upload to the robot control box via serial port/ethernet, and the robot executed it right after it receives the path. very few robot support this: real-time control of the robot joint, including position, velocity, acceleration and so on. As far as I know, only Universal Robot and maybe Baxter support this. Kuka/DLR's LBR(Light Weight Robot) might support it too, but it's not for sale to general public.

Sorry to beat a dead horse here, but just for the record ... 1) To bill Saturday's show as apolitical "entertainment" would be disingenuous. They did not invite Dan Siegel the private citizen to chat with him about his hobbies. They invited three candidates for an upcoming election to air campaign commercials, give stump speeches and answer token questions about their political platform. Exactly that, no more, no less. 2) Absolutely nothing in my critique was "radical". It was barely even liberal. Asking for substantive debate is about the most centrist position you could possibly imagine. Has our overton window really shifted this much?

They had 3 mayoral candidates in the room (parker, tuman, siegel), but chose to interview one candidate at a time. Each candidate got an uninterrupted stump speech, pandering questions from the hosts, then 2 ad-hoc audience questions, and that was it. One even screened a commercial. I was disappointed and insulted because I'd heard it was going to be a "debate." Maybe it got distorted in the rumor-mill. But either way, this candidate-showcasing style of engagement is something people have fought against for ages. It's passive, undemocratic, and pointless. If we're going to engage with electoral politics we should know this history. Here's the League of Women Voters explaining why they stopped hosting presidential "debates" in 1988: http://www.lwv.org/press-releases/league-refuses-help-perpetrate-fraud Some more history: https://en.wikipedia.org/wiki/United_States_presidential_election_debates#D… I think at minimum, a debate needs to: * force candidates to interact with each other * invite all candidates at the same time * prioritize audience participation and engagement We missed an opportunity - we had them on our turf and did nothing new with them - but it's not too late. On October 11 they're hosting 3 more (schaaf, kaplan, quan). Maybe ONL will be open to input on how they conduct next month's event! Any Sudoers who want to ask tough questions on the record of present and future mayors on our turf, now's your chance to get involved. :)

robot tonight

by Jake

to all those who have expressed interest in hacking the robot, i hope to come to sudoroom tonight to play with it some more. i have bolts with which to bolt it down to its pallet, and I will add 2x4 boards to the pallet to make it less likely to tip over. It won't be perfect but it will be good enough to play with, and still easy to move to a different location when the time comes. If you haven't already started, start reading the fucking manuals at this site: http://spaz.org/~jake/robot/ specifically, http://spaz.org/~jake/robot/479950-3-Programming_manual_v4.pdf and if you're into coding and want to control it from a real computer, read this one (and some others, not sure which) starting around page 43 (page 49 of the PDF): http://spaz.org/~jake/robot/479236-17-Communications.pdf I will take care of physically connecting it to the serial port of the 3d-printing desktop computer, so you can connect over the network and operate it that way without having to connect the robot to your laptop. Tonight (assuming i make it to sudo on time) i intend to program it to shake its maraca vigorously to the beat of some music, and bolt it down to its platform.. not necessarily in that order. Oh and hook up the serial cord. -jake
