SandBot Happily And Tirelessly Rolls Patterns In Sand

Posted on by

The patience and precision involved with drawing geometric patterns in sand is right up a robot’s alley, and demonstrating this is [rob dobson]’s SandBot, a robot that draws patterns thanks to an arm with a magnetically coupled ball.

SandBot is not a cartesian XY design. An XY frame would need to be at least as big as the sand table itself, but a SCARA arm can be much more compact. Sandbot also makes heavy use of 3D printing and laser-cut acrylic pieces, with no need of an external frame.

[rob]’s writeup is chock full of excellent detail and illustrations, …read more

Wood Shines in this SCARA Robotic Arm Project

Posted on by

[igarrido] has shared a project that’s been in the works for a long time now; a wooden desktop robotic arm, named Virk I. The wood is Australian Blackwood and looks gorgeous. [igarrido] is clear that it is a side project, but has decided to try producing a small run of eight units to try to gauge interest in the design. He has been busy cutting the parts and assembling in his spare time.

Besides the beautifully finished wood, some of the interesting elements include hollow rotary joints, which mean less cable clutter and a much tidier assembly. 3D printer drivers …read more

Putting More Tech Into More Hands: The Robin Hoods of Hackaday Prize

Posted on by

Many different projects started with the same thought: “That’s really expensive… I wonder if I could build my own for less.” Success is rewarded with satisfaction on top of the money saved, but true hacker heroes share their work so that others can build their own as well. We are happy to recognize such generosity with the Hackaday Prize [Robinhood] achievement.

Achievements are a new addition to our Hackaday Prize, running in parallel with our existing judging and rewards process. Achievements are a way for us to shower recognition and fame upon creators who demonstrate what we appreciate from our …read more

Tiny Vacuum Chamber Arm to Help with Homemade Semiconductors

Posted on by

[Nixie] wants to make semiconductors at home, and that requires some unusual tools. Chief among them is a vacuum chamber to perform thin-film deposition, and true to the hacker credo his is homemade, and will soon be equipped with a tiny manipulator arm with magnetically coupled mechanical controls.

If [Nixie]’s setup looks familiar, it might be because we featured his plasma experiments a few days ago. He was a little cagey then about his goal, but he’s come clean with his desire to make his own FETs (a project that is his 2018 Hackaday Prize entry). Doing so will require …read more

Evezor Robotic Arm Engraves 400 Coasters

Posted on by

When you’re running a Kickstarter for a robotic arm, you had better be ready to prove how repeatable and accurate it is. [Andrew] has done just that by laser engraving 400 wooden coasters with Evezor, his SCARA arm that runs on a Raspberry Pi computer with stepper control handled by a Smoothieboard.

Evezor is quite an amazing project: a general purpose arm which can do everything from routing circuit boards to welding given the right end-effectors. If this sounds familiar, that’s because [Andrew] gave a talk about Evezor at Hackaday’s Unconference in Chicago,

One of the rewards for the Evezor …read more

Ancient Robot Creates Modern Art

Posted on by

They say that there’s more to a Jackson Pollock painting than randomly scattering paint on a canvas, and the auction value of his work seems to verify that claim. If you want to create some more conventional artwork, however, but are missing the artistic muse that inspired Pollock, maybe you can put your creative energies to work building a robot that will create the art for you.

[Dane Kouttron] was able to get his hands on an old SCARA robotic arm, and was recently inspired to create a paintbrush-weilding robot with it for the 2nd Annual Robot Art competition. Getting …read more

Creo Arm Might be the SCARA You’re Looking For

Posted on by

A SCARA (Selective Compliance Assembly Robot Arm) is a type of articulated robot arm first developed in the early ’80s for use in industrial assembly and production applications. All robotics designs have their strengths and their weaknesses, and the SCARA layout was designed to be rigid in the Z axis, while allowing for flexibility in the X and Y axes. This design lends itself well to tasks where quick and flexible horizontal movement is needed, but vertical strength and rigidity is also necessary.

This is in contrast to other designs, such as fully articulated arms (which need to rotate to …read more
