AxiDraw on Stage

In unusual uses for our drawing machines, AxiDraw is playing the role of the master of ceremony in Joël Maillard’s play “Last sheet (after the big lack)”, a production about the robotic future being put on by Theater Marie in Switzerland.

Signal Generator Musical Instrument

Our friend Arjan van der Meij made this charming musical instrument from a signal generator, a servo motor, an Arduino and a processing program. He wrote an instructable for it so you can build one, too.

He also wrote about his experience with the project in Dutch on makered.nl. Projects like this one, that started with a question (“Why don’t you build a machine to do it?”) are great for learning new skills. I often get asked what things someone should get for learning electronics, and my answer is usually that the first thing you need is a project that you want to make so that you’ll have motivation to research what you’ll need.

3d printed knob adapter connected to servo motor and signal generator

Arjan wanted to learn tinkercad, and used this project toward that goal by modeling the knob adapter he’d need for connecting his servo to his signal generator knob. Even if you don’t want to make a musical instrument from a signal generator, this project may provide inspiration for trying out new techniques.

Robotic Art Contest 2017

The second annual Robot Art contest Is in its final lap:

The Robot Art 2017 competition will be running between now and May 15th when more than $100,000 in awards will be given to the top painting robots. Winners will be determined based on a combination of public voting, professional judges consisting of working artists, critics, and technologists, and by how well the team met the spirit of the competition – that is to create something beautiful using a physical brush and robotics.

You can help by voting on the artwork now!

Introducing the AxiDraw V3

We are pleased to introduce the AxiDraw V3, a new generation of our flagship writing and drawing machine.

This new AxiDraw has been redesigned from the ground up for high performance. It features smooth rolling wheels on custom aluminum extrusions, specially designed for high stiffness and light weight. Its sturdy, rigid construction gives it finer quality output and in most applications allows it to operate at up to twice the speed of the previous AxiDraw, which it replaces.

As with the previous version, AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the body of the machine, making it possible to draw on objects bigger than the machine itself.

AxiDraw V3 is available to order today, and begins shipping next week. See it in action and learn more on the product page.

Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself.

The AxiDraw is a fantastic machine for making art — along with all those other things that you might use a pen-wielding robot for: Making “hand written” invitations, signing forms, or making neater whiteboard art than one might otherwise be able to.

AxiDraw is available to order today, and begins shipping next week. See it in action and learn more on the product page.

From the mailbag: Bristlebots and Scribblebots

A few years ago I used your bristlebot design for one of my kid’s classes as a project and it was such a success I’ve done it for each kid (I have 4).

We also made made “pontoon” versions of your bristlebots with 2 toothbrush ends underneath a cardboard oval so it looked like a beetle and gave the kids more decorating space.

Well, now I needed a new project and I came up with the easiest, cheapest Scribblebot I’ve come across, using mostly your bristlebot construction.

The big discovery is that a Dixie cup plus mini markers keeps the whole thing so lightweight. Then put your foam taped pager motor and battery combo on top. It was also way cuter with some antennae and googley eyes. Thank you again for your great bristlebot – it’s made me the most popular mom in each of my kids’ classes.

The bots shown were made by her daughter Kate who also demonstrates them in the video clips. Thank you Kate & Jessica!

Super Awesome Reporting on RoboGames

Super Awesome Sylvia has posted a video report from this year’s RoboGames. Highlights include a couple of combat matches, one of Sylvia’s LEGO competitions, WaterColorBot receiving a medal, and Sylvia completely geeking out after Grant Imahara interviewed her in the audience. (For extra fun, watch the raw footage of the interview from RoboGames.) Our STEAM shirt makes a cameo, too.

A Lego Mosaic Printer

JK Brickworks made this amazing “pick and place” style Lego Mosaic Printer:

It is built entirely using LEGO parts. It first uses the EV3 colour sensor to scan the source image and save the data on the Mindstorms unit. It can then print multiple copies from the saved image data. The 1×1 plates used for ‘printing’ the mosaic are supplied using a gravity feed system and the printing head is simply a 1×1 round plate that can pick up and place the 1×1 plates.

More information about this project can be found at JK Brickworks.

MakerCon 2015

MakerCon is a short conference put on by Maker Media in the week leading up to Maker Faire about the business of making.

Gael with InMoov

3D printing is a common maker topic, and MakerCon brought a few different twists to it. Above is Gael demonstrating InMoov, an open source 3D printed humanoid robot. There was also an incredibly inspiring talk about applications for medical 3D printing by Dr. Glenn Green.

Gigabot print

3D printing can be whimsical as well, as demonstrated by this “25 mm” drill bit by Gigabot.

Strawbees

The folks from Strawbees had built a quadcopter rotor cage with a clever servo actuator for flapping sculptural wings.

Clever flex design

I enjoyed seeing this attractive laser cut living hinge at the BotFactory demo.

Rogue Rover

Rogue Rovers are electric semi-autonomous ATVs designed for agricultural use to reduce farm injuries and pollution.
