TL;DR
A maker named Lahiru Maramba has created a physical version of Rocky, the alien engineer from Andy Weir's novel *Project Hail Mary*, using a Raspberry Pi Zero and a Whisplay hat. The project is powered by a local large language model (LLM) called Gemma 4, which runs on a MacBook Air. Maramba focused on getting Rocky's voice just right by programming a series of friendly tones in Python.
