These Robot Legs Were Made for Walking

Motherboard, the online magazine and video channel dedicated to the intersection of technology, science and humans, speaks of CYBERLEGs:

The CYBERLEGs Wireless sensory system

During the past several weeks, the CYBERLEGs team has been hard at work integrating the new sensory system!

All the CYBERLEGS sensors are wireless and they are being received by a completely new custom-designed wearable board! All the communication is running at 100 Hz through ZigBee (IEEE 802.15.4).

The insoles were redesigned to provide better wearability and they no longer use bluetooth for wireless transmission of data. The entire sensory system data is read into the CYBERLEGs low-level control system through FPGA.

When I get a chance, I will post some nice images and presentations of the wireless wearable sensory system, but until then, you can feast your eyes on this video:

Wearing the CYBERLEGs hip exoskeleton

Being the one wearing the exoskeleton in the video CYBERLEGs@ Rovereto EU Robotics Forum, I thought I could comment a bit on how it was like!

When the UL team arrived at Rovereto early Wednesday morning, we were blown away by the level od detail with which the new autonomous hip exo was crafted. Only being used to the "old" first prototype, which had to be controlled through a separate control unit, the new CYBERLEGs exo was slim & slender, gently packed, light and autonomously powered. The SSSA team even shaved off a lot of width at the hips, so it was pretty narrow!

However, I was unaware that the exo was fully operational. That's why I was really stoked when I got the OK from our project manager to take it for a test drive. You know how it starts with each new thing you get to test. You work with it really carefully, taking good care not to break anything, move slowly and with care. Well, so did I when Mario and Marco slid the exo around my waist. But then the fun started ;D

The first half an hour we took the exo for a walk around the building, but took the elevator as a precaution. Boy, were we stupid. It's really much more fun to take the stairs, believe me! For the first two times you take the stairs up, you really do not realize the range of mobility the exo has. I mean, it has some awesome passive degrees of freedom, but the motors in the saggital plane are super fast and the mechanics really thought through. It shows that the SSSA team put a lot of effort into the new prototype and learned a lot from the 1.0 version.

The amazing 3 hours of autonomy allowed me to take the exo around Rovereto, to the park for a walk in the sunshine. And, despite Rovereto being home to a bunch of robots that week, I got some pretty cool looks and comments. I walked normally and the exo proved to be wearable. The control based on the series elasticity was fast. I tried to destabilize it, but I found no way. For which I am thankful, because you never know, right?!

Luckily, safety was covered in the exo, both by the mechanics (which break if the come even close to harming my leg) and the several control safety features, including the famous "RED BUTTON"!

Anyway, I made some nice photos with plenty of nice girls around Rovereto and I hope I can share them as soon as I can get my hands on them.

Look around when you go to a supermarket in Pontedera or Firenze. You never know if you will see a guy wearing the CYBERLEGs!

Welcome message.

Welcome all to the blog of the CYBERLEGs project. In the next months we will provide updates about the development and the integration of the year-2 prototype and the live demonstrations with real end users.
