Small Quadruped Robot UPDATE : October 23, 2012Apparently some guys got trouble opening the CorelDraw files attached before. So I exported those files into various extension : cmx (to be opened in any CorelDraw version), pdf & eps (for Adobe Illustrator). They're attached as "Quadruped Files 2.zip" UPDATE : October 15, 2012Attached the arduino code, CorelDraw file for circuit board & laser cut acrylic.Sorry for not attached these file before. The code is lame and very unprofessional, so you might want to use your own code. Hi, I'm new to LMR as a member. First, sorry for my bad English. I finished making my quadruped robot a couple weeks ago. It's a wandering quadruped robot with only one ultrasound sensor. I didn't use inverse kinematics for legs movement. I use 12x HXT900 micro servo (3 DOF each leg). So, there it is..
Stubby the (Teaching) Hexapod Since we started, Stubby has grown from a simple, direct-driven 2 DOF (degree of freedom) per leg frame to a mechanically-assisted 3 DOF per leg design with a full inverse kinematics engine (which allows the processor to calculate custom foot positions for each step, rather than relying on a static loop). This video shows off the latest version, including various features of the Inverse Kinematics engine: Originally, the concept of Stubby came from the SG-1 universe's replicators (which, let it be known, are completely awesome!). After the interesting parts (most notably the frame design and inverse kinematics engine) were completed, I wanted to expand Stubby's abilities. When finished, I plan on having an Ultrasonic Distance sensor and a magnetometer, together allowing users to write code for autonomous operation. Please refer to Youtube for THP Submission video and THP Semifinals video. First are the frame plans. The second important diagram is the circuit board schematic.
Piccolo, the tiny CNC-bot Customizable crossguard lightsaber, from The Force Awakens On Friday, November 20th, we were part of the 30 million people to keep their breath while watching the trailer for the next Star Wars movie. As designers, we were surprised to discover a new configuration of the lightsaber revealed in the now epic (and polemic) scene showing an unknown Sith Lord walking in a snowy forest. As Makers, we couldn’t help but try to find out by ourselves if this “crossguard” design was a good configuration or not... So we decided to build one, with our army of 3D printers. Of course, the "darkness" of the movie sequence and the lack of details on the weapon itself left a lot of place for imagination and interpretation. A dozen of 3D printable lightsabers being already available for download on internet, we decided to make one that would be completely customizable. Download all the files on our Thingiverse page or Cults, or Youmagine. I sincerely hope you'll have as much fun building your own lightsaber than we did.
