As part of the Politecnico di Milano AIDA project, I led the design and fabrication of a versatile sensor assembly for autonomous Maserati and Fiat vehicles, specifically targeting urban transportation scenarios. The project demanded a solution that was both robust and adaptable, ensuring reliable data collection under real-world conditions. I then interfaced with these sensors to implement UI that dynamically displays their output.
Developed a highly modular sensor housing using Solidworks that allowed for quick disassembly and reconfiguration, making it easy to access, replace, or adjust camera and LiDar sensors. The housing consists of 8 parts that press fit together to grip the shells and wires of four cameras. A 360° view LiDar then slides onto the top of the assembly, and four nuts and bolts sandwich the assembly together. This flexibility was critical for rapid prototyping using FDM printing and iterative testing in a dynamic research environment.
Enhanced an internal application interface using ROS and Python, allowing for real-time visualization of sensor data and status monitoring. Specifically, I built functions that translated data from a live server into UI components which displayed information such as the location of the car on a scrolling map, the acceleration vector of the car, and whether or not certain sensors were connected.
Engineered a detachable mounting system using suction cups fastened to a rigid PVC platform, enabling the sensor assembly to be mounted on any commercial vehicle. This adaptability facilitated widespread testing across different vehicle models without the need for custom installations. The design was tested to withstand high-speed wind forces, all while minimizing the overall cost and spatial footprint.
This project not only reduced costs by 40% compared to the previous assembly but also significantly improved the efficiency of the data collection and processing pipeline, contributing to the advancement of autonomous vehicle technology at Politecnico di Milano.
