EXTRM MK4 Robot Re-design

At Ross Robotics, I played a pivotal role in the comprehensive redesign of the MK4 robot, transitioning from plastic and carbon fiber construction to a more robust and EMI-resilient sheet metal body. This redesign was driven by the need to enhance the robot's durability and performance in demanding environments, such as high-voltage and electromagnetic interference (EMI) zones.

One of my key responsibilities was the development of the Pan-Tilt unit, which required precise integration of cameras and sensors to ensure optimal functionality across various operational scenarios. Additionally, I engineered the drive system, which utilized a BLDC motor coupled with a belt drive, to achieve greater reliability and efficiency under harsh conditions.

This project demanded rigorous testing to ensure compliance with industry standards, particularly the IEC 61000 for electromagnetic compatibility (EMC). I oversaw comprehensive testing procedures, including EMI immunity and emissions, hot and cold soaking, and vibration testing. These tests were critical in securing the platform’s IP55 rating for environmental sealing and its acceptance for deployment in sensitive high-voltage converter halls across Europe.

The redesign of the MK4 robot not only improved its resilience and adaptability but also set a new standard for robotic performance in challenging environments. This project highlighted my ability to manage complex engineering tasks, collaborate with cross-functional teams, and deliver innovative solutions that meet stringent industry requirements.
