you should probably 3d-print an open source robot arm and start tinkering! the huggingface SO-101 arm i used here is a great start (needs a better gripper).
there's so much you can do now. i think that so many people will have these cheap robot arms in their homes very soon!!
i gave astra a robot, a paint brush, and a camera then asked it to paint the golden gate bridge in real life!
it figured out how to control the robot, and progressively got better throughout its attempts. the timelapse is sick
