Walking Robot with an Uno and Servos

thingiverse

This is a little walker robot that uses a few simple parts. There are two brackets that hold the servos, two claw-like feet that attach to the gear of the servo, and there is a tray that holds the Arduino. Just 4 screws or bolts are needed to mount the servo brackets to the Arduino tray. The feet for the servos can be swapped out with the white plastic servo arm that normally come with servos. Parts needed: Arduino Uno 2x Servos (main body dimensions around 20mm by 40mm by 50mm) A battery pack for portability 4 screws about 3.5mm (~1/8") diameter You also of course need a computer and a USB cable to program the Arduino. You can find some sample walking code on codebender: https://codebender.cc/sketch:158819 The code and build was not made with a particular "front", depending on how you mount the servo brackets one side may work better as the front than the other side. This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/dDf9SkGWbBT Note: it appears the servos I used for this design were discontinued (of course). I'm not sure how common the size is, but if you have servos that don't quite fit and you want help re-sizing the brackets I'd be glad to do a new one to fit it and add that to the project.
