Saber

UPDATE: I no longer publish on Thingiverse. For those wishing the Sketchup Design Files for Saber, they are here: https://www.youmagine.com/designs/saber and here: https://www.myminifactory.com/object/26924. Both locations "saber.zip". Best wishes. ** UPDATE!!!** The prototype Saber has been running a little over a year. By our calculations, taking 1 stride every 2 seconds equates to 30 strides a minute, 1800 strides per hour, 43,200 strides per day, and 15,768,000 strides per year. With a rear leg stride of 5 inches, that equates to approximately 1500 miles non stop (Saber runs on a bench with a UPS, and the shop has a 65kw backup generator, so Saber hasn't stopped for over a year). Thanks Thingiverse for the feature of Saber! As always, I am truly humbled and honored. And many thanks to those who liked and collected Saber! NOTES: 1) See UPDATES below for updates to the design and files. 2) The original Saber is motorized. If you wish to hand operate your Saber, I've uploaded a hand crank module that replaces the motorized module here: http://www.thingiverse.com/thing:1368351. END OF NOTES. Saber is my interpretation of, and was inspired by, the "Disney Computation Designs of Mechanical Characters" video, "Cyber Tiger" segment (link to video follows below). If you are in the Dallas, Texas, USA area on January 31 through February 2 2016, and want to see Saber in person, attend the SolidWorks convention and visit the Ultimaker booth as Saber and some of my other Ultimaker 2 printed designs will be there, as will I. I would enjoy meeting all of you who attend. As to the development of Saber, Thingiverse member sofiadragon1979 suggested that I design and print this thing after seeing "Perseverance" (http://www.thingiverse.com/thing:348489) which was inspired by the same Disney video, and of course Sisyphus (thanks sofiadragon1979 for the suggestion!) . Not having access to the original details, plans nor software that Disney used, I took liberties in the design of the framework, gear train and arms by using my own software (now I know why trigonometry class was useful, who knew?) and design tools in order to better accommodate 3D printing. Standing almost 204mm (8") tall, and when fully extended 304mm (12") long (from head to toe), Saber is quite large, yet it was designed such that it is printed in smaller components in an effort to allow a wider variety of 3D printers to print it. Saber is the most mechanically detailed Thingiverse thing I've published and is indeed a challenge to print and build, so please do not hesitate to comment if you have questions, problems, complaints, suggestions or whatever, and I'll do my best to address them. I hope you build one, and I hope you enjoy it! Video of Saber prototype is here: https://www.youtube.com/watch?v=KSYqz6YY63c. Some have expressed interest in the software I wrote to assist in the design of Saber. A short video of it simulating the front left leg design is here: https://www.youtube.com/watch?v=TbzAQyXUwXs. Video of Sabers made for friends and clients here: https://www.youtube.com/watch?v=5f6ZmdwUVzE. More Sabers here: https://www.youtube.com/watch?v=yCFsUsHfFYQ. And last yet certainly not least, the inspirational Disney video is here: https://www.youtube.com/watch?v=DfznnKUwywQ. Designed using my own software (to generate the framework, gear trains, cam, cap, axle and arm motions) and Sketchup Make 2015. The prototype was printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill). All subsequent Sabers were printed in PLA on an Ultimaker 2 Extended using Cura default settings. UPDATES: Sorry for the update delay as my wife's father, a retired Detroit, MI. police officer, passed away during the December 2015 holidays. My wife and I dedicate Saber to his memory. 1) Uploaded new "Head Right.stl". Old one is not correct, sorry for any problems. 2) Uploaded new "Head Right.stl". Previous upload didn't work, sorry for any problems. 3) Uploaded close up gear train photo of Saber prototype showing the correct initial positioning for "Arm Axle.stl" components for the left side. The right side "Arm Axle.stl" components are rotated 180 degrees from those on the left side. The positions indicated in "Assembly.skp" and "Assembly.stl" are not correct and I will update both as soon as possible, sorry for the problem. 4) For those with large format printers, I've uploaded "Base One Piece.stl", a one piece base.
