When will all the competition gets ended ? because currently working on this project so i need some use cases of these project's programmings and ML models

[@Overengineering2]

The world championship ends on the 21st of july. Some time after that we may open source our code.

[@eyadahmed55]

Do you connect the raspberry pi 5 with a type-c cable from the step down converter directly or how you connect it with the step down convertor?

[@Overengineering2]

We use a power only type c cable that directly goes from the step down converter that is set to 5.1V to the Pi

[@loky2187]

When will be the overenginering github organization made public as you told that , the github repo will publically available in the mid july . I am currently working in this type line follower robot project . So it will more helpful for me to build the project when the github made public

[@Overengineering2]

We just finished the world championship and are working on cleaning up the repository so we can publish it. The first video is being edited at the moment and should be online tomorrow.

[@eyadahmed55]

How do you connect the raspberry pi to the buck?
Do you cut a type c cable or what?

[@Overengineering2]

We use a power only type c cable that is connected to our step-down converters

I'd love to know what you use to sense body position. You can see it shows ten data points, the gyroscope for Angle, what's the position?

[@Overengineering2]

We use 2 Adafruit BNO055 Gyroscope sensors

[@mostafahagras4831]

@@Overengineering2 Why 2 sensors?

[@Overengineering2]

@@mostafahagras4831 we use 2 because they have a slight drift over time so we can average them out

Which engine shield do you use? good job

[@Overengineering2]

Thanks! What do you mean by "engine shield"?

[@limaotop3913]

@@Overengineering2 which shield to control your motors do you use. And what camera do you use?, thanks, good job

[@Overengineering2]

@@limaotop3913 We use a L298N Motor Driver that is connected to our Raspberry Pi 5 through the GPIO pins. The top camera (left image) is a Raspberry Pi camera V3 and the bottom camera (right image) is a Arducam B0268

Hello, do you communicate between the Arduino board and raspberry-pi, if so how? congratulations on the work

[@Overengineering2]

@@limaotop3913 Thank you. The arduino that reads out sensor data we have it print the data into the serial console and then have the pi read it out through pyserial. The arduino that drives our servos is connected through 4 digial pins. The first one is a control pins that says if the arduino is allowed to move the servos at all. The other 3 are the ones who tell the arduino what position to move the servos in. For example a combination of 001 would be move the servo's so the arm goes to the default position.

How do you detect the silver tape and the silver balls??

[@Overengineering2]

We use two different self made AI models for that.

[@hamidoosama]

@@Overengineering2 can you tell us for lerning
