Wobbly - The Slope Walking Automaton

thingiverse

See Wobbly's walking video here: http://youtu.be/DtdJB49f4Yk Wobbly is a mechanical, 3D printed toy robot that can traverse slopes without the need for a motor or batteries - he runs on gravity! To get him in motion, insert a coin into his Rocket Pack accessory (formerly, you had to Blu-Tack a coin onto his back). Attach the head to the body using glue and assemble the 3D printed arms, legs, arm spacers, and arm end stops. The Body and Rocket Pack require support during printing. If you're having trouble getting Wobbly to walk, follow these tips: adjust the floor slope gradient, ensure the surface has enough grip without being too grippy, experiment with arm positions for better balance, and add weight as needed using a coin or by repositioning Blu-Tack. The amount of weight required depends on the slope's gradient and Wobbly's weight distribution. Wobbly was inspired by an automaton created by Roberto Lou Ma; you can view his work and instructions for making a wooden version at http://blog.dugnorth.com/2010/09/wooden-ramp-walking-robot-toy.html. The 123D Design source files are now available for download, and the Instructions tab on the website provides detailed assembly instructions and tips to get Wobbly walking confidently. Share your creations by posting comments or pictures; the creator would love to see more of Wobbly's brothers/sisters. Remember to update your 3D printer firmware regularly for optimal performance.
