The mechanical + electrical + embedded-software design discipline: actuator selection and sizing, gear trains and mechanical power transmission, microcontroller-to-actuator interfacing (motor drivers, H-bridges, PWM), and the multidisciplinary design process and sensor fusion techniques that tie it all together.
Compute output torque, output speed, and mechanical advantage for simple and multi-stage compound gear trains, with per-stage mesh efficiency by gear type.
Compute required actuator force from load mass, mounting angle, friction, and acceleration, and get an electric vs pneumatic vs hydraulic recommendation.
Find the PWM duty cycle for a target motor speed and get an H-bridge / motor driver recommendation sized to continuous and stall current.
Mechatronics does not have a single NCEES PE/FE track the way civil or mechanical engineering does — instead, the recognized credentials are hands-on industrial skills certifications from the National Institute for Metalworking Skills (NIMS), covering the electrical and fluid power systems that make up a mechatronic system, plus the motion-control and PID fundamentals that underpin servo, stepper, and closed-loop motion design work across the field.
NIMS Mechatronics Electrical Systems prep: motor control, relay/ladder logic, sensors, PLC discrete and analog I/O, and lockout/tagout electrical safety.
NIMS Mechatronics Fluid Power Systems prep: pneumatics, hydraulics, directional and flow control valves, cylinder force/sizing calculations, and ISO fluid power schematics.
Motion Control & PID Fundamentals prep: PID theory and tuning, servo and stepper motor control, encoder feedback, sensor fusion basics, and control loop stability — foundational for any mechatronics or robotics motion work.
