Tape. Beer can. Gallon of stain.

I mean, how else are you supposed to test a robot arm? Also, we know EXACTLY what we're doing, as always...

Looks like you finally found a practical use for a robot arm.

What's the model of it? Looks large enough to actually  be useful.

Side question:  It looks like the laptop in use there has two network ports.  Is that the case?  I don't think I have seen one like that before.

It's a Dobot. It was rated at 500g, but struggled to lift a beer can at ~350g. That face I'm making is because the stepper motor ran out of torque trying to lift the can and it flopped down.

No. One Ethernet port. The blue cable is USB. HDMI port at the front.

We're still learning. We will either modify the dobot, or possibly build our own arm that iterates on the dobot's design.

MOAR POWER!!!

One thing to look at is the gain on the stepper drivers. They may not be pushing max current to the steppers. 

Push it till it smokes!

Thank you,

The other option is more gear reduction.  I'm pretty sure you can find more planetary gear box stages that can be slapped on the steppers.

That's what she said.

Anyway, we'll be playing with the robot arm some more during open house tomorrow.
