Mark it on your calendars, folks — this is the week that the term RUD has entered the public lexicon. Sure, most of our community already knows the acronym for “rapid unscheduled disassembly,” and realizes its tongue-in-cheek nature. But given that the term has been used by Elon Musk and others to describe the ignominious end of the recent Starship test flight, it seems like RUD will catch on in the popular press. But while everyone’s attention was focused on the spectacular results of manually activating Starship’s flight termination system to end its by-then uncontrolled flight at a mere 39 km, perhaps the more interesting results of the launch were being seen in and around the launch pad on Boca Chica. That’s where a couple of hundred tons of pulverized reinforced concrete rained down, turned to slag and dust by the 33 Raptor engines on the booster. A hapless Dodge Caravan seemed to catch the worst of the collateral damage, but the real wrath of those engines was focused on the Orbital Launch Mount, which now has a huge crater under it.
[Jongwon Park] and his team of students at the Korea Advanced Institute of Science and Technology have created a fast biped robot based upon the Velociraptor. Raptor weighs in at just 3Kg, and stands only 470mm tall, yet it is capable of running at 46 km/h. That’s almost as fast as Boston Dynamic’s Cheetah.
Raptor uses carbon fiber composite legs to absorb and release energy while running. The system is similar to that used in high performance prosthetic legs. A rotating tail assembly further helps to balance Raptor on rough terrain. We have to admit, the tail system does look a bit dangerous for any humans who might need to interact with the robot. It does work though, as evidenced by Raptor bounding over Styrofoam blocks.
The Raptor robot is quite impressive when running at full speed. Considering this project’s budget was nowhere near the resources of Boston Dynamics, it’s an amazing accomplishment. The video reminds us of Boston Dynamics founder [Marc Raibert’s] early robots at the MIT Leg Lab. We can’t wait to see what this team produces in the future.
