2. Project Overview
An remote controlled robot arm with 6 degree of freedom. It consists of two major component control sleeve and robot arm. Control sleeve is responsible for measuring the motion of the human arm. Robot arm will mimic the same motion.
The additional degree of freedom is from the rotation of wrist.

3. Overall PCB design consideration
Separate components into three modules:
Power Supply
Communication modules(XBee)
Digital circuit(microcontroller)

4. Preliminary PCB layout for Control Sleeve

5. Preliminary PCB layout for robot arm

6. Microcontroller PCB layout consideration
Decoupling capacitor
Level convertor
Robot Arm MCU
Control Sleeve MCU

7. Power Supply PCB layout consideration
Wider trace for GND and VCC
Heat dissipation on linear regulator
Control Sleeve Power Supply
Robot Arm Power Supply
