Day 115 – A Wheely Good Day

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...

Day 114 – UPS Experiments

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...

Day 113 – Filament Forever

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...

Day 112 – Crack the Case

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...

Day 111 – One Inch more

A short update. Each S.A.R.T model/prototype has a new and quite frankly, interesting addition or modification. Every time a new model is printed, something new comes along that needs to be added or measurements are a fraction of a millimetre off, thusly the never ending “Hamster-design-cycle/wheel” keeps rotating. Matthew latest brainchild is to add mounting...

Day 110 – Rebranding

The site we got our original logo from updated their commercial use license, meaning we need to update our logo. Fortunately, this gives us the chance to put some more thought and effort into it! Here’s our old logo. It represents innovation and synergy and empowerment… Yeah. It doesn’t really represent us. We had some other designs,...

Day 109 – Cable Management

After the excitement of Christmas wore off, we started to fit all the items into the case. We discovered that some of the new items were larger than reported online, and thus everything didn’t fit perfectly inside the Treka-700 case. Fortunately, we have another option. We’ve switched around the roles of our cases, meaning the...

Day 108 – Christmas! At least for us.

This morning I was told my Mr. Crane that our new NUC, UPS, and keyboard arrived. As I had a free first I went into the office and unboxed everything! CyberPower UPS This will be used to power the whole S.A.R.T control console, it was the best option we could think because we have items...

Day 107 – Unboxing

Our new toys have arrived in the mail! Dynamixel AX-18A Servos We’ve purchased 4 AX-18A servos from Dynamixel. Apparently, these are the “next step up” from the popular AX-12A servos, which we were actually using for the S.A.R.T v1. The website states they offer nearly twice the speed and 15% more torque. Our old servos...

Day 106 – Robot Prototype 2

3/3/2017 – 21:21  Sit Rep: I started printing the robot chassis with no raft about ~1/2 hour ago.  It looked good for the first 10 minutes and then the printer head obviously hit one of those sensors on the side of the chassis.  This screwed up the printer head alignment and caused the printer to “think”...
