Maker Upgrades Nanosaur Robot With Custom PCB
7.0
A maker in June 2025 upgrades the 2022 Nanosaur robot with a custom SMD expansion PCB, Jetson TX2 NX, and IMU, and documents build challenges and solutions. They designed the PCB in KiCad, ordered Osh Park boards and a Tropical Stencil, solved TPU tread issues, reflow-soldered a QFN ICM20948 IMU, and integrated a ROS2 IMU driver and TF transforms for rviz2 visualization.
Key Points
- 1Adds custom SMD expansion PCB with ICM20948 IMU and JST connectors, enabling robust hardware connections
- 2Solves mechanical failure points and improves reliability over dupont headers and stiff TPU treads
- 3Demonstrates reflow SMD, QFN handling, ROS2 IMU driver integration, and native Jetson TX2 NX deployment
Scoring Rationale
Practical, well-documented DIY upgrades offer replicable guidance, limited by single-project scope and absence of broader benchmarked results.
