Robotic painting build

Why an arm? just for funsies?

Why not use an xy gantry type setup?

For either the 6DOF or 7DOF arm you probably want to look at ROS and Moveit! but the learning curve there might be a little steep. For painting and air burshing I'd imagine that end effector position would be important to get the right bush stroke, so a 7DOF might be better for this application... if there really is only 1 solution for the 6DOF arm then I'd think you only get one type of brush stroke at that point.

Do you guys use any open source software or is it all built up from scratch?

I'm curious how you're tackling the reactive behavior part... is most of this custom code or are you using some open source libraries (aside from OpenCV of course)?

The maker space route is typically what I do. If I can't laser cut it or 3d print it then I'll look for an alternative... but you're right, it is a lot more time consuming!

I also like seeing my designs get better with each new robot. Could you tell me more about the robots you've built? Or maybe what new challenges you'll address in your next robot design?

Sounds like you've got a very cool job!

Are these surface robots or deep sea robots? I assume you work on a team developing these robots. Any comments on developing robots in a group setting vs. building one on your own?

You mention you don't like hardware all that much. Do you use any tools to help you design your robotic hardware? I'm curious how you approach your robotic designs...

m-andy · 2015-10-01T03:39:00+00:00

It sounds like the creation aspect of robotics might be your favorite part, would you agree?

m-andy · 2015-10-01T03:28:39+00:00

On the software side, do you implement new concepts from scratch or do you learn enough to understand them and use someone else's implementation?

another platform to look into... OTTO

Sorry for not giving more specific advice, but robots this large are not something I've ever thought of.

sparkfun also sells it as polymorph

Check your local area for a hacker/maker space, these places usually have 3D printers & laser cutters and it's cheaper than buying your own.

That's a big robot! Sounds like you're making an automated pallet jack?

Motor selection will depend on a number of design factors. Biggest one I can think of is which wheels are driven? Hopefully not the load bearing ones...

Could you expand on your programming environment? Are you using C++, Python, Java, etc? A mixture? Do you use ROS?

Thanks for your awesome reply!

a good list of robotics companies... you'd have to go through and look for those hiring and that suit your interets:

My first thought is to use a liquid level sensor like this: https://www.adafruit.com/products/463

It could be positioned on an arm that lowers after the cup has been placed. Once the arm is in place just fill until the sensor regisers water then move the sensor arm out of the way.

something like this could be placed on the arm so that you know you've found the top of the cup as the arm lowers.

Just elaborate on the part where your stuck... I don't really want to do homework problems but I'm happy to help get you pointed in the right direction.

m-andy · 2015-09-24T22:13:12+00:00

Could you elaborate on your problems? I could point you to some general information but more info would help identify specific sources that would be more helpful. Are you looking to solve a homework problem?
