We just published our article “Have LEGO Products Become More Violent?” at PLOS One. Here is the abstract: Although television, computer games and the Internet play an important role in the lives of children they still also play with physical toys, such as dolls,...Read More
This is my latest MOC: A LEGO Unikitty! It is 180cm tall and features a rotating head and sparkly eyes. It took several month from planning to finish and never used as many pink bricks in my life. Still, the color combination is just cute. The neck uses my LEGO compatible...Read More
The Govenor General, Jerry Mateparae, visited the HIT Lab NZ on March 9th, 2016. We presented our main research areas to him, including Human-Robot Interaction. Jerry Mateparae seemed to enjoy the performance of our robots, but his Aides-de-Camp looked, well, I am not sure how...Read More
Sounds easy, I wish it was!
To rotate an axial load LEGO developed the turn table. For light loads this works great but the friction increases dramatically with heavy loads. This thrust ball bearing uses standard LEGO balls to transform the friction into rotations. This allows the two disks to easily rotate. The balls and an additional rim keep the two disks in place.
A motor can be attached on the inside to power the rotation. Even the smallest LEGO motor is sufficient to easily rotate this 2 kg load. This thrust ball bearing is fully LEGO compatible and even allows studs to be attached to top half. Standard 14.2 mm LEGO balls can be used. The bearing measures 20 studs across and is three bricks high. This should be big enough for even the biggest crane or MOC display.
The 3D data is available from the Autodesk Gallery.

We have been working on balancing a robot on top of a ball, similar to what BB8 accomplishes. We used a robot balancing on top of the ball instead of inside it. This is work in progress.
Many products are being sold that are suppose to increase your energy. Unless your food is completely indigestible, this will always be true. Food by definition has calories which provide you with energy. But food manufactures have moved on and this trivial definition of energy is rarely used. These days energy food typically contains Caffeine. In particular energy drinks, such as Red Bull, Mother and V contain a considerable dose.Read More
We have just published a nice study in which we developed and tested Emotion Rating Figurines (ERF) that allows you to assess emotional responses. The figurines are base on LEGO Minifigures. We developed a questionnaire sheet and also a physical model.Read More
The IFIA World Congress and Innovation Conference in Stockholm invited me to give a speech on why innovations fail in academia. I gave this speech on August 25th, 2015. I hope you enjoy my presentation.
