Little Climbing Robot

cults3d

This clever robot's mechanical principle is based on a classic toy that lets the robot climb up the string when you pull on it. Check out this YouTube video for the robot in action and watch it being assembled from start to finish. Get "Climbing Robot" Merch and show off your love for this amazing project! As a modular print, it's an excellent project for newcomers to 3D printing who want to experiment with settings part by part. If a print fails, only a little time and material are wasted. Overall, the print does not pose any challenging printing tasks. Last but not least, it's also a great way to recycle your filament leftovers and create a really colorful bot that stands out from the crowd! 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, which worked perfectly. A normal rubber band might also work, but it's probably not as long-lasting. In any case, the band must be no wider than 5mm (0.19 in) or thicker than 1mm (0.04 in). Not all strings will work for this robot, as the correct amount of friction in the robot's "hand" is crucial for the climbing action to work. The model is optimized for a ca. 3mm (0.1 in) 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. This video has step-by-step assembly instructions if you need them. If your printer is tuned to produce correct dimensioned parts, the robot will friction fit together. Otherwise, just 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 clamp hard enough to hold up the robot's own weight. Use a round file to smooth out the bottom of the groove the rope runs through in clamp-p1.stl and remove all the 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 bore out the hole with a fitting drill. I chose a 3.5mm drill for the 3mm rope I used. That's it! Don't forget to share your make and show off your amazing creation!
