A working prototype, from every angle
An advanced humanoid robot built for expressive movement and embodied AI
Unmodified LEGO® design
The robot is built entirely from unmodified and unglued LEGO® elements. This allows builders to use parts from their existing collection and source any missing pieces through marketplaces such as BrickLink or similar platforms. It is a more affordable and environmentally friendly approach that encourages reuse and recycling.
Real-world development
This is not just a concept. Robert is an actively developed physical project with evolving mechanics, software, motion control, and interaction systems.
Power without complexity
Ease of usage.
Robert is designed to be approachable without sacrificing capability. Advanced functionality should not require a complicated user experience. While the experience is intentionally designed for simplicity, the underlying architecture remains fully explorable for those curious to look deeper.
