About
Built through iteration.
I'm Jonah Chang, a student engineer at Cape Elizabeth High School. I design, build, test, and revise mechanical and software systems, and keep every result grounded in what can be measured. On VEX team 56S, I'm the main programmer and primary CAD designer.
Mechanical design
From concept and CAD to manufacturable assemblies.
Control systems
Localization, motion planning, and feedback control.
Computer vision
Perception and ranging for real-world systems.
Embedded computing
Software that runs where the system does.
