How it works

We developed a custom power measurement PCB equipped with high-precision shunt resistors. This board monitors voltage and current consumption across all subsystems (Motors, Compute, Sensors).

An STM32 microcontroller aggregates this data and publishes it to the ROS2 network, enabling the system to estimate remaining battery life, track efficiency trends, and trigger power-saving modes when necessary.

Technical Implementation

• Sensors: High-side current shunts
• INA: Texas Instruments INA237
• Data Points: Voltage (V), Current (A), Instant Power (W)
• Integration: Custom ROS2 message type over I2C/CAN bridge
