Servo Robotic Arm: Electrical

This electrical system is nothing to write home about, its simply three cheap buck modules in parallel dropping 18-25.2V from a 6S LIPO battery down to 6V for the servos. The 6V power rail provides power both directly to the Servos and to the Vin pin and the Arduino UNO. from here the Arduino creates its own 5V rail and powers the NRF24L01 module present in the device.

Electronics of the Servo Arm

Even though the decisions that led to this setup were based on a single idea, what can I make with the parts I have access to. The system performed as expected and the arm powered on just fine and could move for hours. The biggest thing I would change for a version 2 in the future would involve consolidating systems to lower the total number of wires, and probably switch to a single larger buck converter.
