Hi @larakster.
There are two robot arms on sale in our shop,I think it should work well for your project.
You can see here which Robotic Arms RobotShop sells:

About carrying capacity,
Payload: 200g (Straightenable weight)
Load: 500g (Clamping handling weight)
Because our robotic arm is mainly used to learn the ROS system and Python programming, it is not an industrial-grade product, so it cannot bear too much weight.
But I think it is definitely a robotic arm that is very suitable for your art project.
Hope this helps you.
