We’ve seen robots that move about using wheels, two legs, four legs and even ones that slither like snakes. The Cubli can move despite being just a cube. Actually it does have wheels, but they’re inside its body.
The Cubli was developed by researchers at the Institute for Dynamic Systems and Control of the Swiss Federal Institute of Technology, led by Gajamohan Mohanarajah and Dr. Raffaello D’Andrea. It has three wheels powered by a small electric motor, a three-axis accelerometer, a three-axis gyroscope, a servo for braking and a STM3210E microcontroller.
By taking advantage of angular momentum and torque reaction, the 5.9 cu.in. cube can jump from a stable position, then stop and balance itself on one of its edges or even one of its corners. It can keep balancing even if you push or disturb the surface that it’s on. It can also be commanded to fall in a particular direction. By performing all three actions successively – jumping up, balancing and falling – the Cubli can be made to move around. It cannot speak though. At least not yet.
Read the researchers’ paper (pdf) on Cubli or head to RoboHub to find out more about the robot.

When the Omni VR treadmill was announced, many anointed it as the perfect companion to the much-awaited Oculus Rift. But a group of students at the Vienna University of Technology may have a better VR treadmill at their hands (and feet). They call it the Cyberith Virtualizer.
Much like the Omni VR, the Virtualizer is an omnidirectional motion sensor. It allows the user to walk or run in any direction, as well as jump, crouch and strafe. However, unlike the Omni VR, the Virtualizer also lets the user play while sitting. Another big difference is that its walking surface is flat, makes no sound and only requires that the user wear socks. The Omni VR on the other hand requires users to wear a custom pair of low friction shoes and it makes a considerable amount of noise when used. The video below shows Cyberith founder Tuncay Cakmak play a modified version of Grand Theft Auto IV using the Virtualizer, a Wiimote and of course an Oculus Rift headset.
I’d still rather have wearable motion sensors if I’m ever going to play a VR game, but I think the Virtualizer has great potential. Hopefully someday all of its electronics can be embedded in a less conspicuous form.
