Aaron and I tried to repair the Intel NUC during a free period. A small crack was discovered in the SSD connector, meaning the SSD was not getting any power. We decided to salvage a power supply from an old school computer that had been sitting in the storage room. After removing the power supply,...Read More
Today we talked torque. We’re looking at new servos for the Mark II S.A.R.T robot. Gerard is considering buying 4 of these AX-18A servos. http://support.robotis.com/en/product/dynamixel/ax_series/ax-18f.htm These servos are twice the speed of the current ones on the S.A.R.T Mark I at 97 RPM. The AX-18A servos will be used on the wheels and we will...Read More
Today we were interviewed by the Canberra Times for an upcoming article. We’ll include a scan and possibly a link when it is published! http://www.canberratimes.com.au/act-news/canberra-students-to-compete-at-robocup-junior-national-championships-20160909-grd3nk.html After the interview, the team examined the new Intel NUC provided by Gerard. This is going to be the new “brain” of the robot. It’s far more expensive than a...Read More
During a free period, Aaron and I discussed the possibility of using a new 3D printer filament, CPE. The filament has excellent toughness with resistance to chemicals and temperatures up to 70 ˚C, dimensional stability over longer periods of time, and it’s ideal for short run manufacturing and functional prototypes. We also discussed: A new...Read More
So… RoboCup. Came, Saw, Conquered. After some hard competition and some very tasty schnitzel, Riley walked away with tied first in the maze competition and a first place in one of the preliminary rounds. After that Riley took a much needed two day break, then boarded a train and began thinking. The train of thought...Read More
We’ve had a few internet issues that have set us back a long way. The first issue is that the wireless access points in use here are 5GHz. This means the Raspberry Pi 3 inbuilt wireless adapter cannot connect to the school network, and neither can any of the wireless adapters we’ve tried. This isn’t...Read More
Over the past few weeks, very little progress has been made as most members of the team have been studying for exams. Most exams finished on this day (the 20th of June), so further time can be dedicated to preparing the robot for the international RoboCup competition! Matthew and I discussed options for redesigning the...Read More
Riley spent most of his time building and test fitting the parts for the robot, Ryan spent his time working with Mr Pham on python programming. Aaron was locked up in the 3D printer room working on getting as much printing done for all the people going to robocup. He also took the makerbot home...Read More
An assignment for IT requires students to create a programming project related to the school in some way. We had the option to work on code for the robot, which Ryan and I decided to do. I am working on the front end control interface for the robot. I have documented my progress, which is...Read More
I worked on a new power delivery system for the Raspberry Pi. Originally I designed this schematic: However I later found a simpler PCB that had all the functionality required. This is the device we will use: https://www.adafruit.com/products/1944 This is the PowerBoost 500 Charger. With a built-in battery charger circuit, it can keep the Pi...Read More
