A project log for Mebo Robot Mod with Rasp Pi 4 and Adeept Motor Hat

In this Episode, we rip out the original controller board and replace it with a Raspberry Pi 4 and a motor driver board

I installed 2 WS2812 RGB LED light bars on the underside of the bot and filled in the holes for the line tracker so that they won't look like garbage anymore. Well, less like garbage anyway. But the stock wires for the LEDS were too short. I went ahead and ordered Mini Micro Sh 1.0mm Jst 3-Pin Connector with 150 mm cables to connect them to the hat. So tomorrow I will be terminating the bare ends with JST-XH and now that I am getting better at crimping, it will be a snap! 

When the new bot arrives (whenever the hell that is) I will power it up externally and see if it connects to the app, if it does, then ill post a vid of it running stock. If it can run stock, Ill put it through its paces and see just what one could do with it before making the decision to mod it. 

If it cannot connect to the app, then then i will mod this one as well, BUT I will not tear this thing apart all willy nilly, as i know now that the gripper and wrist needs to be taken apart carefully WITH PICTURES!! 

I am still waiting on my donor servos but when they do arrive I'm going to leave all the stock wiring for the motors in the arm intact as to not have them get all over the place and convert them to hobby servos (5 wires, 2 for motor and 3 for potentiometers to standard 3 wire servo wiring) and that goes for all the wiring coming down through the arm. I don't need to take that apart completely, only enough to properly identify the wires for each motor/ potentiometer group conversion. all the servo driver boards will reside in the base
