Test development includes mechanical fixturing, circuit board design, firmware development, integration of existing equipment, and contributing to how test data is collected, validated, and used to inform engineering and manufacturing decisions—defining how data is collected, validated, stored, and interpreted to inform product performance, failure analysis, and manufacturing decisions. The Matter Compiler is aimed at micro-machines: motors and gears the size of a grain of sand, robots small enough to work inside the body, cooling built directly into the chips that run AI, and the many devices like them that have been waiting on a way to build them.
