Devlog 3 I have decided that i will be making my own PCB for this project. I alrady have my microcontroller picked out, i will be using the CAN bus protocol to communicate with the stepper controllers. Each controller will gets its own PCB that will be addressable, these smaller CAN boards will nee dthere own MCU, they will feed the main controller inputs like encoders, limit switches. another CAN bus will just drive the motors, the final CAN bus will be a smart end efector system. I am going to make modular end effectors for variouse tasks. each end effector will have its own smaller mcu that can basicly tell the main board that is is a camera module, or a vaccuum, or a 2 finger gripper.
