Imagine a live, 4k video version of Google Earth. The whole planet, all the time, live and to the minute. Speeding is now impossible, because traffic control is completely automated. Troop buildup and movement is monitored constantly, making surprise attacks very difficult to pull off. How does a major oil company control the story about their latest leak or explosion when everyone can watch the plumes spread as they happen? Even petty crimes become difficult.
Assuming (and it’s a big assumption) that the data isn’t being doctored. There’s no way to be certain anyone broadcasting data is telling the truth. If only we had a lot of individually controlled cameras all broadcasting a corroborating story. Oh, look! Project Tango. Hm.

Researchers at John Hopkin’s University has been building innovative robot teaching systems using new technology. Here they use an Occulus Rift system to train the robot in a virtual environment.

Testing is essential. Testing is repetitive and boring, so humans are bad at it. Automated testing is the way to go. But what do you do when your app is on a phone or a tablet? Someone has to sit there and tap every button… until now. See video

The Three Arm Delta Robot v2 was always open source, and today I’m delighted to announce that it is finally open hardware, too. That’s right! All the custom parts are on Thingiverse. You can 3D print the arm parts, laser cut the frame, add then an arduino and some servos and some threaded rod to build your own Delta Robot.
No time? Look through our selection of delta robots and find a best-fit for your needs.
Still not quite right? Use our handy calculator to design your own and then contact us! We’d be glad to help make your dream come true.

Starting at 11:00 AM PST today I’ll be hosting a Google Hangout live from VHS. Eat breakfast while learning about 3D printers. The best reason to get out of bed since cartoons!
If this text is blue click to join us, too. The hangout is archived so you can watch it again. It’s like that new Norwegian “Slow TV”.

I want to add spray painting to the Makelangelo. Instead of lifting the pen off the paper it will push on the nozzle of the spray can to make a dot. Sounds simple, right? the devil is in the details. Read the rest of this entry »

Delta Robot v3 has just been updated with tool offsets and tool changing.
Tool offset GCODE commands are G54 to G59. The basic system supports 6 tools at once.
G28; home the machine
M114; report position. Z should be 4.77
G54 Z-2; adjusts position down 2cm
M114; Z now appears as 2.77
If you have more than one tool then it would be nice to have a way to have the machine remember the offsets for several tools at once. This update adds memory for all 6 tools. G54 will change tool 0, G59 changes tool 6, etc. M06 Tn will tell the delta that you have switched to tool n.
You can download the latest firmware from the delta3 open source repository on github.

Google Analytics tells me that we’re now getting >11,000 visitors a month here. That’s one every five minutes! Come say ‘hi’ in our forums. Get to know one another and talk robotics. Together we can collaborate, teach each other, and make awesome things happen.
Case in point, deanville just posted this modded version of his Makelangelo 2 pen holder in the gallery section. He says … well heck, you can read it for yourself.

Knitic has created an open source knitting machine. The custom parts look 3D printed. Very neat!

First off: Why six?
6 degrees of freedom is the minimum needed to reach a volume of space from every angle. The longer the arm, the greater the volume that can be reached. More than 6 joints and the robot becomes kinematically redundant – it can reach the same spot at the same angle in more than one way. For example, you can pinch your nose and wiggle your elbow at the same time.
In a human arm there are at least six degrees of freedom. If your robot arm can do all of these motions then your arm can do pretty much any job a human can. So here’s a list of what the six degrees are and what they are not. Video after the break. Read on
