Pi IP

Aaron made huge breakthroughs with streaming video from the Raspberry Pi to a computer. While he had successfully used VLC to stream to Windows devices, our Ubuntu laptop was not giving the Pi an IP. Today was the day that the laptop gave the IP to the Pi. Now that the Pi has an IP,...

Basic Construction

Matthew and Riley drilled the holes in the standoff/support for the Raspberry Pi screen, while Ryan and I started working on getting the claw and arm servos working, now that the robot has full range of movement.

What If?

Ryan and I continued to work on the Python script on the Raspberry Pi, fixing a few issues with the code. We now have a robot that can go backwards, whereas before we had a series of statements that would never get triggered: if else if For most of the hour, the entire team worked...

Eventful

Day Twenty One was a very eventful day, and unfortunately we dedicated most of our time to working on the robot rather than working on documentation. The Raspberry Pi, Open CM board and the Open SPMP were all mounted on the robot by Riley, Matthew and Mr Elias. The power supply is currently a series...

Baud Rate

Ryan took the robot home to work on it over the public holiday. He spent the day working with Oarkit’s script for controlling the servos. He put hours of hard work into finding out the dilemma of why neither our code nor Oarkit’s worked on our robot. He finally figured out that it was the...

Sophistication

We discovered a more sophisticated robot design on the internet, which gave us inspiration for a better design (to compete in the National Competition).  Riley and Matthew worked together to decide what parts would be made with different materials and their measurements. The camera apparatus that was mounted to the robot broke today, because of...

Power!

We have started designing the breakout board that will direct power from the lithium polymer battery to the Raspberry Pi, the Dynamixel servos, and anything else that needs power. We have cannibalised a USB mini cable, cutting off the standard USB end and exposing the red 5v wire and the black ground wire to power...

Taking Control

Matthew and Riley printed a few more camera mounts, in case the ones we currently have break. This was an issue we found with the store-bought camera mounts. Aaron is working on connecting a Raspberry Pi to a Linux system. Ryan and I have decided to re-write the two programs required to control the robot,...

More 3D Printing

Riley downloaded Inventor, and Matthew is going to teach him the basics so he can design and print models, as he wants to experiment with the chassis, modifying it so it has telescopic capabilities and is more flexible and stable. I made a video showing how to set up the daisy-chained Dynamixel servos (posted on...

The IT Crowd

Riley and Matthew replaced the tape on the 3D printer bed and reapplied glue, then began printing the newly designed camera mounting apparatus that Matthew had made in Inventor.  Printing at 100% infill and with a layer height of 0.05mm, it took take a while but is going to be extremely strong. Ryan installed Python...
