I want to develop a robotic arm that could lift around 200 grams of wt. and drop it on a conveyor or basket. Is this wt. too much for the Lynx 5 or 6. If so should I use HS5995 or can I use the geared versions from Servocity? Arm length will be around 12 inches max. The object shape is cylindrical (1 inch dia. and 4 to 5 inches long).
I also want to link or daisy chain multiple arms (20 or 30 arms) doing the same repetitve work. Is it possible to control this daisy chained arms thru a single software. That is, if I change the elbow angle in the software, it should affect that angle in all the elbows.
200 grams = 7 ounces
At 12 inches fully extended horizontally, the ideal torque on the farthest servo will be 7*12 = 84 ounce inches.
That’s assuming that the arm weighs nothing, though.
The Lynx 5 is about a pound without batteries.
Subtracting the weight from the base (you won’t be lifting that), and I’m guessing that it’d be around 12 ounces or so.
So 19 * 12 = 212ozin.
You’ll definitely be in the clear with just 5995’s.
I’d definitely stress not buying 5995’s though.
They’re so powerful that they melt themselves under strain!
Instead, get yerself the 5955’s, which have a heatsink.
If you don’t mind the speed sacrifice, something like a 645 or 5645 with a large gear reduction would probably do the trick.
Keep in mind, though, that they won’t then fit the brackets and each gear reduction will add quite a bit of weight.
