Speaking of uArm, an open- source robotic arm, there are so many scenarios that can be found such as writing or drawing, which not merely enrich the amount of use-cases but also add enjoyment and practicability to it.
The initial idea was casually thought up by one of co-founders, Tony. Accordingly, we designed a rough pen-holder by using 3D printer immediately.
The model has a very simple structure: Put the pen into the cylinder half-opened structure; tighten the pen up by locking one side of the screws to make the half-opened circle ring tight. We posted the scheme online and wondered if someone would like this gadget. Unexpectedly, many uArm fans showed us their interest in this pen-holder via emails or messages. Hence we realized we need to improve and perfect our current structure.
After several prototypes and adjustments, we finally made this following structure:
- Concealed Position. As the end-effector, you may not see the overall appearance of the pen-holder since it’s skillfully hidden under the 4th servo motor. The end-effector and the motor seem like a unified entity at first glance, The end-effector allows people to clamp the pen around 7~15 mm for Most of common pens are suitable to it.
- Easy to use. You only need to slide the red button and put in all kinds of pens, which will be easily clamped.
- Delicate details. We actually get what we want in design effect. Sandblasted, oxygenized and diamond-cut the aluminum alloy. The appearance looks simple but you can also find it steady and superior.
It looks not bad! Afterwards we’ll also silk-screen the logo unto it to make it look much better! Do you like it?
Coooooooooooooool
Thank you 😀
