If you’ve read the previous posts about building a CNC machine that understands GCODE, you’ll know that we only went as far as to draw straight lines. In this article we’re going to look at how to draw arcs. Read the rest of this entry »
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.
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”.
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.
