Project Sentinel — A Bipedal Walking Robot

Bipedal-Walking-Sentinel-Project-500x375

[Ye Guan] has always been fascinated by walking robots — so he decided to build his own. It’s called Project Sentinel, and he’s loosely based the design off of the Sentinel Walker from Warhammer 40K, and the two-legged AT-AT walker from Star Wars.

Both of these robots are based off of a bird’s walking style. Scientifically this is called the digitgrade walking style, which means they stand and walk on their digits (toes) — this typically allows them to move more quickly and quietly than most other animals.

[Ye] has managed to achieve this for his project using 8 servo motors, balancing the center of mass directly above the feet. Think about it like a reverse pendulum, which is supported by the servos torque and balanced by a gyroscope. He plans to have it fully autonomous with sensor feedback.

It’s not done yet, but he’s already released all the CAD files and a nice build log for anyone to attempt it themselves — we’re excited to see the final product. Just take a look at it walking in place after the break!

MountainBeest – A Theo Jansen Creature Comes Alive in My Garage

About a year ago, a member of my family sent me a video featuring [Theo Jansen's] StrandBeest, knowing that I was interested in all kinds of wacky and hackish inventions. My initial reaction was something to the effect of “wow that’s a neat device, but that guy is a little crazy.” For better or worse, the idea that this was an incredible invention turned over in my head for some time. Eventually, I decided that I needed to build one myself.  Apparently I’m a little crazy as well.

Theo’s original beest runs on a complicated linkage system powered by wind. He was nice enough to publish the linkage lengths or “eleven holy numbers,” as he calls him at the bottom of this page. He doesn’t, however, really explain how the connections on his PVC power transmission system work, so I was left to try to figure it out from his videos.  As you’ll see from build details and video to follow, this isn’t trivial. Keep reading past the jump to learn the adversity that I encountered, and how it was overcome in the end.

RC car transforms into RC robot

Transformer

After nearly 30 years since the first episode of Transformers aired, someone has finally done it. A company named Brave Robotics out of Japan has created a true transformer robot that is half remote control car and half remote control bipedal robot.

According to the Brave Robotics’ site, this creation is the result of more than 10 years. In 2002, the first version of the Transform Robot was completed – a relatively simple affair that transformed but couldn’t walk or drive. Over the last 10 years, the prototypes have seen incremental improvement that included a drive system for the wheels, a steering mechanism, and even the ability to move its’ arms and shoot plastic darts.

Surprisingly, you can actually buy one of Brave Robotics’ transforming robots for ¥1,980,000 JPY, or about $24,000 USD. A little pricy but we’re sure we’ll see a few more transforming robots in the future.

Check out a few more videos of the Brave Robotics transform robot after the break.
