Pneumatic compressor for the 6-axis robot arm with auto start/stop

The grabber of the robot arm is opened and closed by pneumatic pressure. Therefore, I needed an air compressor that can generate a pressure of approx. 20 – 30 Psi. But how do you manage this air pressure? If the motor keeps running, the air pressure becomes too high. If you switch the motor on and off manually, you need to stay alert and watch the manometer if the air pressure doesn’t become too low. The solution: build an automatic start/stop system. In this article you can read how I achieved this.

Lego World Utrecht 2015

Sioux.NET on Track will be showing their layout at Lego World 2016 in Utrecht, The Netherlands. The layout will be present on Saturday Oct 22 until Monday Oct 24.

This year, the layout will be controlled by 13 Mindstorms bricks (1 x NXT and 12 x EV3). Four visitors in a row can choose a color and the train is getting them in one run. New items in 2016: completely redesigned candy factory, candy crane with power chains, redesigned delivery station and much more.

Videos of the building in progress can be viewed at the Youtube channel: www.youtube.com/user/siouxnetontrack.

Color selector for Lego World 2016

All years, we use a color selector device (we call it the PUI, the Physical User Interface) as the starting point of our track. Over the past years, the PUI looked like this:

Engineering the new delivery station for Lego World 2016

For Lego World 2016, we are engineering a new delivery station. Some background information: in the 2015 version, the candy crane grabbed the candy directly. Unfortunately, too often the candy fell out of the grabber during the movement of the crane. Therefore, we decided to update the crane that it would pick up the complete container (with the candy, of course :-)). The crane update is already finished as you can read in our previous article. In this article, you can read about the ideas of the new delivery station.
