Climbing Robot

thingiverse

This little robot's mechanical principle is based on a traditional toy that lets it climb up the string when you pull on it. Check out this YouTube video for the robot in action and watch it being assembled. As a modular print, it's a great project for newcomers to 3D printing as it allows them to experiment with different settings from part to part. If a print fails, only a small amount of time and material is wasted. Overall, the print doesn't pose any difficult printing challenges. Last but not least, it's also a fantastic way to recycle your filament leftovers and create a really colorful robot. Get "Climbing Robot" merchandise here. The Climbing Robot Accessories contain a hat and a backpack for the robot. Happy printing, and don't forget to share your creations! Parts List --- In addition to the printed parts, you'll need an elastic band and a string. I used an elastic band commonly available for textile work, but a normal rubber band may also work. However, it's likely not as durable. The band should be no wider than 5mm (0.19 in) and no thicker than 1mm (0.04 in). Not all strings will work, as the correct amount of friction in the robot's "hand" is crucial for the climbing action to function properly. The model is optimized for a string with a diameter of around 3mm (0.1 in) or 2mm. Two versions of the clamp are available for download, and from my experience, a coreless braided string works best. Revisions ------- 22/01/2019: Added a clamp for a 2mm diameter string. 23/01/2019: Fixed the orientation of the clamp STL files. Printing --- The model is optimized for printing with a 0.4mm nozzle, and the sloped surfaces look their best with a 0.2 layer height. However, larger layer heights won't cause any problems. Most of the parts are designed to be printed without support and are oriented correctly in the STL file for optimal printing.
