Made a board with all the electrical components needed for Alpha bot.

Programming tried to test drive code on the Alpha bot but 1 of the Kraken motors had a faulty connection.

Unscrewed the cap of the Kraken connection adapter and retightened all the screws that made a connection. The motor was then fixed.

The CANchain was also broken.

Went around the entire can chain testing connections with a digital multimeter. Through re-doing all the CANchain connections we fixed the CANchain.

Programming checked to make sure the computer could see all the components. All components are visible.

YAY CANCHAIN!

Configured the new radios. They should all have their firmware updated. There are 3 configured radios and 1 radio that was a dud out of the box. Put new radio on AlphaBot.

Tested different retroreflective sensors with CORAL and ALGAE at different positions

Observations :

Allen Bradley retroreflective sensor: Works for both CORAL and ALGAE, shows orange light if tripped, uses 12V

Long Distance Reflective Switch (OPB720A-06Z): Works with both ALGAE and CORAL, accurate when tripped, smaller than Allen Bradley sensor, uses 12V

OMRON retroreflective sensor: Works with CORAL well, could be mounted with a cutout underneath the CORAL intake

Decisions: We are leaning to use the OMRON retro reflected sensor (image 3) for CORAL. Mounting it in the back by either the top of the middle plate facing down or the bottom of the bottom plate facing up. It would need to be mounted such that it's face is flush with the plate. Needs a mounting plate that can accomplish this and also provides back and forth adjustability.

Leaning to use the big diffuse retroreflecting sensor (image 1) for ALGAE. Mounting it on either left or right side of the middle plate. Mounting it on the underside of the middle plate sideways such that you can access the adjusting screw. It's mounting situation also needs to be adjustable back and forth.

Communicated all of this to game piece for them to keep it in mind for their design.

Fixed one diffuse sensor lmao because the signal wire broke off. i inhaled so many fumes :(      -meow

Discussed sensors for game piece again. Probably will need 2 separate sensors for either game piece. Discussed the algae perhaps having 2 sensors so the motors can switch to a slower speed for gripping after initially intake at a higher speed. This should also be for noticing if the algae was slipping and needed to be intook and regripped again.

Measured enough PWM cable for the elevator

Looked at Magnetic Limit Switches and IGUS Chain for the elevator

Talked about absolute encoders for the write of Coralge

1/25/25 Tested Magnetic Limit Switch REV 31-1462: possible sensor for elevator to sense MIN and MAX Switch works 10mm on top (front part) and 5mm on the sides(front part), the back doesn't sense (where the wires connect), two identical points to connect signal We are thinking about getting a stronger or bigger magnet so that it is more consistent when mounted Searched for 180 degree turn potentiometers; found those that turn around 270 degrees Sorted the rest of the potentiometers Sorted new electrical parts(AND FIXED THE ZIPTIE BOX)
