Bring me a bottle (tabletop arm)

Tabletop arms (and mobile bases with a cheap manipulator) can do useful fetch if you constrain the scene: one bottle type, known table height, clear grasp axis. Detect with color/depth or a small vision model, plan a grasp, lift, and place on a marked pad. Start in Gazebo/Isaac before trusting real grippers near glass.

Curated seed / example for arm-class hobby platforms and sim. Not a Unitree humanoid skill.

Safety: no glass bottles for v0; use plastic. Keep hands clear of the workspace.
