This repository contains the design files and documentation for the Power Distribution Module developed for an Autonomous Mobile Robot (AMR) platform. The focus is on compact, reliable, and high-current-capable power delivery to all major subsystems.
In mobile robotic platforms, reliable power management is essential for ensuring safe and efficient operation. This project introduces a custom-designed PCB to manage power distribution from a high-voltage battery source to multiple modules including:
- Motor drivers (6–7 A each)
- Onboard computer (e.g., Jetson Nano)
- Microcontroller unit (MCU)
- Sensors (e.g., LiDAR)
- Stable system on-off through relay
-
High-Current Copper Pours
Top-layer copper pours are used for high-current paths (e.g., motors) to ensure thermal performance and reduce voltage drops. -
Dedicated Ground Plane
A full bottom-layer ground plane provides a low-impedance return path, minimizing noise and improving signal integrity. -
Compact PCB Layout
The board is designed to fit within the tight mechanical constraints of a mobile robot chassis while maximizing current delivery and thermal efficiency. -
Modular Connectivity
Outputs are routed to standard connectors for ease of wiring and modularity.
- Input Voltage: 22.2V (from 2× 11.1V LiPo in series)
- Total Current Support: Up to 20 A combined
- Power Paths:
- Motors: 2 × 6–7 A
- Jetson Nano: 5 A
- LiDAR: 2 A
- MCU: 2 A
