Today was Individual Evaluation 2! Because I was fortunate enough to be evaluated closer to the end, the day in the shop was pretty productive.

After remounting the encoder system with a smaller crossbar and battery mount, it was time to begin integrating the circuits and electromechanical subsystems. Mason set up the fuse and emergency switch on the…

Many milestones were hit this week for our team. On Tuesday, we started the beginning of the long integration process, testing out how Tom's coded pulse width modulation would work through Mason's driver board when connected to the fully mounted (and functional) motors. The results were very promising.

On the electromechanical side specifically, The final structure of the robot is complete. The motors were remounted using steel strapping instead of plumbing fittings, which…

Today was pretty standard - went to the soldering seminar, and then hit the shop around 3:00. The day was spent prototyping our arm design.

Our arm is passive - we have no motors or actuators attached to it. The concept is pretty basic - small, light balsa wood strips are mounted to a rotational bearing that is centred in the robot, mounted 45cm up. On the end of the arm, elastic bands are used to both stabilize it (preventing unwanted bouncing etc.) and as the…

Man, Wednesday section is packed. I don't think I'll go back to Wednesday sessions unless I REALLY need the time... lots of people who didn't have labs must have come also, and the tools were in high demand, along with the workspace.

Today, both motors were successfully mounted to the base. The transmission system is complete! I am very proud of my handiwork, as it took me around 2-3 hours to get the alignment of the gears perfect. The result is worth it though - I'll post a…
