Robert is the result of decades of hands-on experimentation, intuitive problem solving, and a long-standing interest in mechanical creativity.
The project was not planned as a product first. It grew naturally from a way of thinking focused on what works, what lasts, and what opens the door to new possibilities.
The path into professional LEGO® Technic™ design did not begin with a standard application. It began with a robot, a plane ticket, and the decision to simply show up.
When Johann was 15 years old, in 1989, he built a LEGO® Technic™ robot controlled using train track switches and ribbon cable wiring. It could drive on caterpillar tracks, operate 8 motors, lift objects weighing up to 400 grams with a multi-jointed robotic arm and gripper, and even included a front winch.
At the time, LEGO® was not producing anything remotely like that, so he had a simple thought: why not ask them if he could help develop it further?
So he bought a plane ticket to Denmark, took the train to Billund, walked into LEGO® reception late on a Friday afternoon, and asked if he could apply for a freelance design job.
By remarkable luck, the head of the Technic department at the time, Mr. Ole Vestergaard Poulsen, happened to still be in the office. He agreed to meet Johann, looked at photographs of the robot, and explained that LEGO® designers also needed strong model aesthetics, not only technical problem-solving skills. Still, he invited Johann to send more examples of his work.
During the following Christmas holiday, Johann built additional models and mailed photographs to him. A few months later, he received a letter asking whether he would be willing to take a design test.
The test consisted of five identical bags of LEGO® Technic™ parts. The task was to create five completely different model proposals, each using at least 80% of the supplied pieces.
Among those parts was the Technic Gearbox 2 × 4 × 3 1/3 (part 6588), which at the time represented LEGO’s standard worm-drive housing geometry. While working on the test, Johann developed the compact 8-tooth worm-drive housing concept that LEGO® later adopted.
At the time, LEGO® worm gears were typically paired with 24-tooth or 40-tooth gears. The compact 8-tooth worm-drive arrangement did not yet exist as a standard building solution.
During the design test, Johann developed the compact housing concept shown below. The underlying construction concept later became part of LEGO® Technic™ design language.

One detail Johann has always found curious is that the worm screw itself was never shortened for this configuration, despite half its length serving no mechanical purpose there.
LEGO® later informed Johann that he had passed the test with excellence and specifically noted that he used the supplied parts in “new and exciting ways.”
The contract took additional time because LEGO’s legal department needed to prepare a new arrangement for what Johann was told was their first foreign freelance designer working remotely.
He was still in junior college when he began working with LEGO®, initially designing B-models - alternate models for official sets - during summer periods.
After graduation, he asked whether there would be enough ongoing work to continue. LEGO® responded by sending approximately 100 kilograms of LEGO® to Iceland so he could continue developing ideas and proposals.
Several years later, Johann stepped away from that work. When he did, LEGO® told him not to return the bricks in case he ever wanted to come back.
After several years in storage, Johann asked LEGO® for permission to use that collection for creativity courses for children in Iceland. The goal was to teach engineering fundamentals, creative thinking, and problem-solving through hands-on building.
What began as a small side project grew into something lasting. Johann still teaches those creativity courses today.
In many ways, Robert is a continuation of that same journey.
Johann spent several years designing for LEGO® Technic™ after being invited into the system through an unusual but successful application path. That background shaped his instinct for mechanical clarity, serviceable structure, and creative use of standard elements.
For more than 25 years, Johann has taught creativity classes in Iceland, focusing on practical problem solving, original thinking, and the ability to turn ideas into working systems. Robert grows directly out of that same mindset.
Robert did not appear all at once. The project grew through experimentation, public progress updates, refinement, and a series of important milestones that gradually shaped it into what it is today.
The guiding principle is simple: do what works, and avoid what does not. The design process is about simplifying everything until the best, and often the only, solution has been found. The goal is to make complicated things as simple and robust as possible.
Limitations are not treated as reasons to stop. They are treated as signals that better design solutions may still be waiting to be discovered.
Robert was not shaped by copying what is common. It was shaped by looking at what the system needed to do, then building the most practical path toward that result.
The goal is not to remove complexity from the machine. The goal is to absorb it into the design so the finished platform feels clear, reliable, and easier to understand.
Robert is not an isolated invention. It is the result of years of exploring how simple ideas can lead to complex, functional systems.
Robert combines mechanical design, embodied interaction, modular electronics, and AI control into one platform. But it also reflects a broader way of thinking: solve the real problem, simplify what can be simplified, and let practical results guide the direction.
Robert is one step in a longer process. It is part of a broader creative journey that includes other inventions and long-term ideas still in development.
The years leading up to Robert also included the development of other major ideas and inventions. Robert is the first public expression of a much wider design direction.
The long-term vision is not just to make one robot. It is to help open new possibilities in embodied AI by combining practical mechanics, serviceable design, and systems that people can eventually build, understand, and expand.
Robert is still evolving. Follow the project to see new milestones, design breakthroughs, demonstrations, and the next steps in the journey.
