After printing some wheels in PLA I thought we could speed this up if I got the Ultimaker and started printing them on that as well. As I’m using the Ultimaker I’m using ABS to print the wheels, not only is it better quality it is also a stronger plastic so with that in mind we are...Read More

Ever since I created the S.A.R.T interface, there’s been one thing that bugs us constantly, and that’s having to refresh the page to load the stream every time we restart it. Refreshing the whole page has other unwanted effects, such as closing the SSH connection, meaning you have to log back in if you were...Read More

The final pieces of the control-panel-puzzle are in place, with the arrival of our new UPS and monitor. Over the past few days, we have assembled the control panel and even started testing it too. Aaron and I first prepared the case by giving it a good clean – over the past few weeks a...Read More

As part of our control panel, we needed to extend the UPS power on cable this is because we wanted to be able to turn it on without removing the plastic every time. It should have been simple, go online and look for a 4 pin cable that is the same as what the UPS...Read More

With the robot well under construction, we’re soon going to need the S.A.R.T Control Panel in order to test it. With that in mind, I marked out holes for fans, cables, the power button and the power LED.   After lunch, Aaron and I went to the applied tech department to cut out the holes....Read More

So. We have a problem. Like Tom Hanks stranded on an island, level problem…. In short, stuff doesn’t work properly. Long version: The Robot’s current mounting system for the servo’s looks like this: Each servo is held on by four screws, one 3mm and three 10mm. Each of these screws need to be able to...Read More

I took the 3D printer home again this weekend and printed the 6th chassis prototype, with the extra room for the SSD underneath the NUC, instead of on the top of the robot. There were some minor design changes that were necessary to accommodate the SSD underneath the NUC.  The entire robot is about 5mm...Read More

After a discussion with Aaron yesterday, this morning I set up an experiment to test how long the UPS would run after being disconnected from the wall. The devices I connected was the BreezeLite mini PC, the Xirrus access point and POE injector, keyboard, mouse and monitor. The UPS was able to power these devices...Read More

Over the past few weeks, we’ve been running very low on 3D printer filament, only being able to print a few test prints every time a new shipment of filament comes in. Today we went on a hunt for the extra filament that we had last year. We looked in the old office, in the...Read More

Our current design has the UPS sitting in the pelican case like so: Unfortunately, in order to power it on, we would need to stick a finger down into the case and press the power button. This just isn’t as elegant and sophisticated as we would like. So, I decided we should rip the front...Read More
