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...

Console Peasants

Ryan and I discussed how the PlayStation controller will be used to control the robot. We mapped most of the buttons and both joysticks to various robot functions, and also created a small program to print strings such as “Moving forward” or “Instant Speed Boost” when the R2 and X buttons are pressed respectively. The...

Achievement Get: Taking Inventory

Upon arriving at school, we discovered that the gear arm we started printing the previous day had been misplaced.  As a result, we had to start printing it again, then about halfway through the print, we noticed that the end was peeling up (this occasionally happens if you don’t have enough adhesive on the print...

3D Printing

After some testing with Dynamixel Wizard, I discovered an issue with the claw mount servo. Mounted in the way it was, the arm would not be able to rotate all the way to the front of the robot. To fix this, Riley removed the arm, rotated the servo 90 degrees forward and then reattached it,...

Dynamixel Day

Ryan and I connected a single Dynamixel servo to the Dynamixel2USB and the SMPS2Dynamixel, but had trouble connecting more than one. We soon discovered that the IDs of the servos would have to be assigned individually, and searching for the unassigned servos with Dynamixel Wizard would not work. So, we connected each servo individually and...

Fixing Computer Bugs

I began the overhaul of our team laptop with Aaron and Ryan. We would eventually be using this to program and develop the code necessary for the robot.  We took it apart and cleaned it out because we were concerned about temperatures. We fixed a “bug” by removing a small insect that had somehow found...

Of Claws, and Not Much Else

We can begin assembly of the claw as soon as we figure out exactly how all the pieces fit together with only two reference pictures (included below).

Of Wheels, Plastic, and Not Much Else

We didn’t spend long on the robot today, just a few minutes to get the main body finished. Matthew and I have removed the excess plastic from the two front wheels. Matthew attached them to the robot after holes were punched by Riley using a screwdriver.
