A closer look
Every intelligent machine has a physical design: structures that carry loads, electronics that deliver power, and mechanisms that turn commands into movement. This family develops those systems and the processes used to build them.
The work spans engineering, fabrication, assembly, and hands-on testing. A design is only useful if its components fit together, withstand real conditions, and can be manufactured consistently.
What the work involves
Translate performance requirements into component designs, prototypes, and test plans. The practical decisions include materials, dimensions, heat, power, wiring, tolerances, and how the finished system will be assembled and inspected.
IN PRACTICE
Building a robot hand
Mechanical engineers design the fingers and transmission. Electrical and firmware engineers connect sensing and motor control. Technicians assemble prototypes, while manufacturing engineers work out how to build and inspect the hand repeatedly.

Skills & qualifications
Degree pathways are common for engineering roles; technician pathways can include an associate degree or postsecondary certificate. The relevant preparation depends on whether the work centers on design, embedded development, assembly, or testing.
Technical foundations
- CAD and engineering drawings
- Mechanics and materials
- Circuits and instrumentation
- Embedded C/C++
- Assembly and test methods
In day-to-day work
