Phase 2: Hardware & Electronics
Software is nothing without hardware to run on. Phase 2 gets your hands dirty — you'll learn which computers and microcontrollers power robots, how motors turn electrical signals into physical motion, and how sensors give robots a perception of the world around them.
Why hardware matters
Every software decision in robotics is constrained by hardware. Understanding what a servo motor can and can't do — or why a LiDAR costs more than a camera — directly shapes the algorithms you'll write. Phase 2 makes you fluent in the physical layer.
1. Microcontrollers & Computers
Arduino for low-level motor control, Raspberry Pi for Linux-based robots, NVIDIA Jetson for AI at the edge. Learn which board to choose and why.
Explore Microcontrollers →2. Motors & Actuators
Servo motors, stepper motors, brushless DC, hydraulics, and pneumatics. Each has unique characteristics — understand trade-offs in speed, torque, and precision.
Explore Motors →3. Sensors & Perception Hardware
LiDAR, cameras, ultrasonic, IMU, force/torque sensors — a robot's sensory organs. Learn what each measures, how to interface with it, and when to use which.
