Climbing Robot

myminifactory

This little robot's mechanical principle is based on a traditional toy that lets it climb up a string when you pull on it. Check out this YouTube video to see the robot in action and watch it being assembled. Get "Climbing Robot" Merchandise. As a modular print, it's a great project for newcomers to 3D printing because it allows you to experiment with settings from part to part. If a print fails, only a little time and material are wasted. Overall, the print does not pose any difficult challenges. Additionally, it's a fantastic way to recycle your filament leftovers and make them really colorful. There is a backpack and a hat available for this robot: Climbing Robot Accessories. Parts List In addition to the printed parts, you'll need an elastic band and a string. I used a standard elastic band commonly found in textile work. A normal rubber band might also work, but it's probably not as durable. The band must be no wider than 5mm (0.19 inches) and no thicker than 1mm (0.04 inches). Not everything will work for the string because the correct amount of friction in the robot's "hand" is crucial for the climbing action to work correctly. The model is optimized for a ca. 3mm (0.1 inch) or a ca. 2mm string. There are two versions of the clamp available for download, and from my experience, a coreless braided string works best. Assembly This video provides step-by-step assembly instructions if needed. If your printer produces correctly dimensioned parts, the robot will friction fit together. Otherwise, use glue or tune up the fit with a file or sanding paper if the parts are too large. Tuning the Clamping Mechanism In general, the clamp should clasp just tightly enough to hold up the robot's own weight. Use a round file to smooth out the bottom of the groove that the rope runs through in clamp-p1.stl' to remove all printing striations. Apart from that, it's essential that the hole through the "shoe" is large and smooth enough for the rope to slide through without friction. A good way to achieve this is to drill out the hole with a fitting drill. I chose a 3.5mm drill for the 3mm rope I used. Happy Making!
