robotic arms with gripper that can lift 2 pounds ?

gripper that can lift 2 pounds or more ?

Inexpensive servo based robotic arms for your 2 pounds payload,you may
contact some Japanese Industrail robot manufacturer,such as kawasaki,
Yoskawa.

I should have been more clear. I meant hobby type servos.
But thanks !

These are about the biggest hobby servos out there:

343 oz-in, $40 each

343 on-in / (2 lbs * 16 oz/lb) = 10.7 inches

=> You could build an arm with a ~9 inch max reach to lift 2lb (allowing
for structure and a light gripper) using these for the vertical axes,
and somewhat cheaper motors for the horizontal.

Don't know of anyone selling a prebuilt one, though.  Is there much
demand for one?

Has possibilities! Thanks !

I'm not sure what sort of lifting you're doing (straight up and down
or more complicated motions).  If it's just straight up and down I
would recommend a lead screw.  You get alot of lifting force with very
little torque required.

Any servo can lift two pounds or even move the earth if given enough gear
reduction and time. Please submit more info.


Anyone know of any relatively inexpensive servo based robotic arms with
gripper that can lift 2 pounds or more ?
Thanks !

Something like those offered by Lynxmotion, but beefier. Almost a =
rhetorical question, I know.
D. Herring intuited what I wanted pretty good.
Thanks !

2 pounds is around 1 kg payload. This uis quite high for an
inexpensive robot.
It depands what do you mean by inexpensive.

Here is a suggestion for relatively serious work: the Harmonic Arm 2
that allows you to carry up to 5 kg.

Being designed with harmonic drives, this means you can have obtain
quite accurate movements.

The seller is in Ottawa, so there is no custom duty for people in
North America.
