I didn’t refuse to disclose any value
its pick and place robot arm I even added a youtube video link to which I want a similar one
but I need accuracy, I think about 0.4-0.5 mm is close enough
I added earlier that the end weight will be maximum 1 kg, will be running it 24*7
I don’t know what else info you need, please ask me
I am unable to decide
stepper, stepper with encoder, stepper with gearbox, servo, anything other
Thank you, let’s say 0.5mm is what we want. Now, how long is the arm from the final position to it’s first joint? If the end of the arm must be in position w/in 0.5mm, what is the maximum error in movement that the first joint can make?
Once you can compute that, then do the same for the next joint, using the total distance from it’s joint to the final landing spot for the placement. And continue for the remaining joints.
