So we'll get rolling a couple of minutes after the hour, just to give folks some time to gather
Feel free to start submitting questions if you got 'em!
@ben.phenoptix ?? :)
In the meantime, would you like to introduce yourself
Hi everybody, I'm Ben from MeArm. MeArm is a project that got started some years back now when I lusted after an open source robot arm project. Since then we've built quite a few and there are many many more out in the world thanks to folk like Scott on here who have been sharing the project
The first good version of the MeArm owed a heck of a lot to a chap called Jack Howard, and the latest one a chap called Ben Pirt. It's always been a collaborative project
: Oh yeah doormouse here doing the Drink Crow Badge this year for DC26. Glad to finally make it in time for this weeks chat and touch bases with everyone.
Thanks for joining us for Hack Chat today!
Ready for some questions?
@Elecia White :
First up from
"Have you looked at how difficult it would be to integrate the MeArm into ROS? I tried to make a URDF so the MeArm could work in the Gazebo simulator but couldn't get the shoulder right."
https://hackaday.io/event/156850-building-robotics-hack-chat-with-mearm and, unless stopped, I will keep adding more until @ben.phenoptix redesigns my whole mearm-based project for me.)
(Hey, other people should ask questions too! I have a monopoly over at
Ah Elecia! there's an email I need to respond to! Unfortunately I haven't, most of my time this last year has been sucked up by the day to day running of the business so I haven't had the time to look into the ROS side of things, or listen to your pod cast. That last part I can remedy sooner than the first!
Just chuckling to myself that this is going to turn into all of the emails that are starred but not responed to in my gmail account!
folks are usually a little shy to start out but we'll get more ;)
@Elecia White asked the first few so here goes the next one up: "How are other people doing feedback to get real position of the gripper? "
ROS (Robot Operating System) is used a lot in academic life, I'd love to see mearm added, not just selfishly but also because the on-line modelling means less breakage of the arm as I play with reinforcement learning or motion planning.
Hmmm, I've seen hacked servos used for feedback, like in the UArm. Feedback is something that the MeArm lacks, and it would be good to solve that, but I've always struggled with keeping the MeArm to a price point.
It would be great to have it set up properly in ROS, I'm hoping to have some more time this next 12 months to work on fun stuff with Robotics myself and be freed somewhat from the day to day of running a company.
Adding anything to the capability of the MeArm in terms of feedback just seems to add so much to the cost. I'd be really happy to see of hear of anything cost effective we could do, or even be pointed towards projects that use feedback
Totally understand not wanting to burden the mearm itself, just wondered if you have heard of other people doing common things...
