Move Carefully

Open Loop vs Closed Loop

Understand the fundamental difference between open-loop and closed-loop control — and why feedback is essential for precise robot movement.

PID Control

Learn the P, I, and D terms of PID control — the most widely used control algorithm in robotics — and understand how they work together to achieve precise motion.

Motor Control

Explore the three main motor control modes — velocity, position, and torque — and learn how H-bridges and PWM make precise motor control possible.

Velocity Commands

Learn how to command robot motion using linear and angular velocity, and understand the kinematics of differential drive and Ackermann steering.

Tuning & Debugging

Practical techniques for tuning PID controllers, diagnosing motion problems, and making your robot move smoothly.
