Common Robot Types

• Line follower — 2WD chassis + IR sensor array + L298N + Arduino Uno
• Obstacle avoider — 4WD + HC-SR04 ultrasonic + L298N + Arduino
• Bluetooth robot — 2WD + L298N + HC-05 + Android app
• Robotic arm — 4–6 servo motors + PCA9685 + Arduino Mega
• Balancing robot — 2 DC motors + MPU6050 IMU + PID controller + Arduino

How to Choose Motors for Your Robot

1. Speed vs torque — higher gear ratio = more torque, less speed; match to robot weight and terrain
2. Voltage — 6V motors for LiPo 2S (7.4V); 12V for 3S (11.1V) packs
3. Driver current — L298N handles 2A/channel; BTS7960 handles 43A for heavy robots
4. Encoder needed? — encoder DC motors for precise odometry; plain motors for simple tasks
