1 Servo Walker

See it in action here: https://youtu.be/b5V4SJ_1uzQ This is my take on the one motor walker robot by Burhan Saifullah which is itself a remake of Jerome Demers' (http://www.instructables.com/id/How-to-make-a-one-motor-walker-without-bicore/) Made to accept a 9g modified servo (http://www.instructables.com/id/How-to-modify-a-servo-motor-for-continuous-rotatio/) Built in AAA battery pack with ON/OFF switch (http://www.thingiverse.com/thing:1096639) Added the linkage arms that worked with my setup, should be fairly universal but just in case I added a set of blank linkage arms that can be cut and drilled to size. This is a really fun project made to introduce kids to servos. Enjoy! Print Settings Rafts: No Supports: No Notes: Printed the bushings and linkage arms at 10% infill The body printed at 5% with no problems. No support needed. Post-Printing The link arms will probably need sanding to make them smooth enough to pull/push the arms without snagging. I drilled out all my holes prior to screwing, recommended. I used 1" screws for front and top, a 1 3/4" screw to go through for the side axle. Servo screws were locked down with small pieces of plastic with a 1/16th hole, or you can find very small screw/nuts for these.
