Sprint 2 - Drivetrain troubleshooting, adjustments and add-ons

[LucasN219]

Wednesday - Oct 16 Failures

• The wheels connected to the motor via chain are stiffer and turn slower
• One side was fixed by removing a 3mm spacer, but the other is still stiff

Today, me and Lucas managed to complete the drivetrain with both success and failure.

Success

• Figured out what the issue was with the front wheels turning with a lot of stiffness (it was because of the axels and the misalignment of the motors)
• Checked over the entire drivetrain to ensure no mechanical issues, was successful

Failure

• Have to rebuild the front beam so 90° corner brackets face inward instead of outward

Right now, Lucas and I have completed 99.9% of the drivetrain for our robot. However, we have to complete the 90° corner brackets on the front beam and place them inward. I plan on completing that after school today (Oct 17, 2024) so we have less trouble.

Today (Oct 18, 2024), George and I managed to assemble all the pieces of the robot together after school. With some tests on the field, the robot can score specimens in high chambers & lower baskets.

Success

• Managed to assemble the parts of the robot
• All parts move & operate with no issue

Improvements

• Move the tower back so the arm can fit within 18 x 18 x 18 inch dimension
• Add an extra foot to the arm so samples can be scored in high baskets

This coming Tuesday (Oct 22, 2024), we will discuss further plans on what to do including adjusting the robot, beginning the process of wiring the motors, and starting the process of coding the tele-op part for the robot. Hopefully, we will accomplish these tasks by the end of the month (Oct 31, 2024)

Today, I was able to redesign the intake system as it wasn't properly reaching the upper basket.

Success

• Managed to assemble the intake system
• Added support by adding an additional bar to the arm of the intake system

Fails

• Wasn't able to find the proper screws to attach my pre-built intake system to the rest of the robot
• Wasn't able to assemble the bottom cardboard floor of the intake system
• Couldn't test the arm to see if it could reach the upper basket

For tomorrow's class, I hope to complete the intake system with my group along with testing and seeing if it can reach the upper basket. In addition, wiring up all the motors is another goal I hope to achieve with my group this month.

Wednesday, October 23 Intake system length fixture, assembly and basic wiring

Success

• Found the correct length for the intake arm to reach the upper basket
• Attached the intake arm to the robot
• Basic wiring done with drive train motors
• Robot fits with the 18in. cube

Failures/uncompleted

• Haven't connected wires to a control hub
• The front intake piece hasn't been connected to the intake arm
• Couldn't attach the cardboard to the arm
• Don't know if we can put samples into the upper basket, we have the height but haven't tested it with the code (we don't have code yet)

Tomorrow, I hope to be able to attach the cardboard and front intake piece to the robot

Today, we modified the robot by adding the c-channel from the original instructions inorder to add more stability to the core of the robot.

Success

• Added the intake bar from the 22nd to the robot
• We were able to adjust the robot's intake arm, adding more support with a bar across the intake arm
• We're able to fit within the 18x18x18 inch dimension ever so slightly

Modifications

• Redesign the plastic bottom of the intake system since the last floor was smaller
• added more height and stability to the intake arm

Tomorrow, we hope to keep adjusting the robot and prepare for the coding phase of the robot.

I have forgotten to take a picture today, but I managed to accomplish the following with the team:

1. Fixed cable management for the robot using materials such as zip-ties
2. Finalized the intake system for the robot, holds samples and can make it into the high basket

Next week, we plan on finalizing the robot by adding the rev hub and battery. In addition, we will begin coding the movement of the wheels and arm, hopefully accomplishing it before the end of the month (Oct 31, 2024)
