Fast 140ppm mid sized delta robot

First run of a 15" version of the mini delta with 2x the workspace, but more speed.
We'll see how fast we can get this going... 180ppm... 15g's?

I need to find some soft ware and can these be run off of an arduino?

@madmatt113944

Check out JensOverby. I don't know the Arduino, but he has an amazingly well developed Arduino delta. What software do you need?

Can this robot (or a modified version) work sideways? I.e., rotated so that the board lies in the vertical plane?

[MimixMotion]

@futnuh there is no orientation constraint... it will work in any direction.

AWESOME. Is this the new one you were telling me about? Its so fast

[MimixMotion]

@gastro54 This isn't optimized yet. Very crude settings. I'll get it going faster over the next couple weekends.

I've seen these at shows for a while & think they are pretty neat & also have customers who build / integrate them on machines. Seems like a trend that people want to control from a PAC with motion-logic type controls but it seems like builders are not wanting to build unique arms which i thought they might. The application engineering for the front end and software seems to be a barrier unless the builder is pretty sophisticated. I work in sales for a motion control distributor.

For some reason, only the big boys are brave enough to use these in real applications... ABB, Bosch, Elau and now Kawasaki. Fanuc even has a funky hybrid version. Adept has a 4arm version, but its geometry is less than optimal. These are very cheap, and very fast. There are 3axis and 4 axis. I'm a systems engineer and a motion controls consultant... this is a system I'm developing for University study.

What do you do?

@mnriderdude

Not a math wiz... but pretty good with software tools that do the heavy lifting. Because it is closed chain... all three actuators working together (and against each other in an inertial sense) the dynamics and torque is best left for the simulator to calculate. I always use Delta Tau for mechanisms, and have made several versions of deltas for them as prototypes and marketing tools. I think this is my thirteenth iteration.... from 8" workspace to 42".

@MimixMotion ... thanks - you must be a math wiz.... at my job we get involved in similar applications and not sure i'd be able to help someone specifiy the motor-drive-gearing very well for an application like this seems like some trial and error.

Are you using deltatau for the control?

Are you doing real applications or lab work?

Are you doing 4 true axes or 3 for the kinematic?
