My robot plans have changed significantly - but ive locked myself in on this one

Check out Dorian Todd's Sesame Robot, I want to make a robot with a size like that, as a pet robot droid, with 8 hours battery life droidish language and advanced emotions and movement and pet stuff.

Im planning to get the Flashforge 5M Pro 3D printer in a month and a half or so, and it will not only help with this project, but many to come in the future.
