Overview
Representative of the cheap aluminum-bracket servo arms that dominate classrooms and AliExpress. The xArm 1S uses serial bus servos with position feedback, while LeArm variants use PWM or bus servos plus optional AI vision and voice modules. Good for learning kinematics and block/Python programming, not for precise manipulation or imitation-learning data collection.
