Week 7

Made lots of progress with the catapult, with the winch and latch mechanisms. Progress with drivetrain, with design redone along with more suitable parts.

Accomplishments

Mechanical:

• Design, 3D printing and Assembly of Latching Mechanism
• Design, 3D printing and Assembly of Winching Mechanism
• Spec out and order new components for the Drivetrain

Electrical:

• Keeping up with mechanical changes
  • Added limit switch to latch for automatic catapult control
  • Tested new mechanical features as necessary

Software:

• Started integration of webserver interface with robot's latching and pullback mechanism
  • Things like timing of how long to move the latching lever to get into position (WIP),
  • How long to wait after starting to pull catapult back to start latching (WIP).

Challenges

Mechanical:

• Multiple versions of Winch and latching mechanism prototyped and tested in a very short amount of time to find the version that works.
• Not able to work on the drivetrain since we are still waiting on delivery

Electrical:

• Burned a motor controller, need stronger ones.

Software:

• Testing different timings for movement of latching and pulling mechanism. We need to find some consistency in how to move the latch and pulley.

Plan for week 8

Mechanical:

• Complete assembly of ALL mechanisms and the drivetrain
  • DO WHATEVER IT TAKES to make everything functional. By the end of this week, everything should work mechanically.

Electrical:

• Last components FINALLY came in, so now I can finish the electrical board.
• Do things

Software:

• More integration, testing timing, etc.
• Also control of reloading mechanism, as that should be done by next week.
