Building Sprout: A Mobile Plant Robot Powered by Gemini and TurtleBot 4

The video shows how a team built "Sprout," a houseplant robot that roams an office, finds light for itself, and asks for water when its pot sensor detects thirst. It covers the hardware, software stack, and interaction design used across a roughly two-week build.

■ Hardware and Physical Build
- TurtleBot 4 as the mobile base (a Roomba-style platform with a frame, camera, and LiDAR for room mapping and obstacle avoidance)
- Pixel 11 used for the face and eyes, plus a real Monstera plant and a thirst sensor in the pot
- Design work for the cover shape carried out with Nano Banana

■ Software and AI Stack
- Gemini used to tie the project together, with development carried out in the Antigravity environment
- Gemini Flash for vision, AR 2.0 for segmentation, and Gemini Live for audio
- Sprout making its own decisions in given scenarios, locating light, and caring for its plant friends

■ Assembly and Interaction
- Putting all components together into the finished robot
- Voice-driven behaviors, including requests, jokes, and simple movements

This is useful for robotics makers, students, and hobbyists who want a concrete example of combining consumer hardware with multimodal AI. Viewers can expect to learn how such a project is structured and which tools fit each part of the build, and can use the breakdown as a reference for planning a similar prototype.
