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.
I wrote a small test program for the robot arm to load the train with two containers. Loading the two wagons was done in one minute, so much faster than the candy crane.
Have a look at the video and please share with me what you think of it.
I have written a small test program for picking up a container from a pre-defined place. It is still a bit slow, but it works.
For 2017, we are building a robot arm with 6 degrees of freedom.
As you can read in the first article about the Ticket Dispenser Unit (click here for the article), the version for Lego World 2016 a ‘fast build’. Nevertheless, it worked almost flawless. Almost … sometimes the card was not transported to the end. With just some small modifications, it works even better now.
A video impression of our layout at Lego World Utrecht 2016 has been uploaded to our Youtube channel.
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.
