Overview

Product type: Servo kit. This Yahboom SG90 servo with platform for smart car combines a 9g micro servo and a mounting platform for building pan/tilt-style ultrasonic scanning on a smart car. It is designed for distance measurement and ultrasonic obstacle avoidance experiments with 180° angle range rotation.

Key Features

  • 180° angle range rotation
  • PWM control reference (cycle: 20ms): 0.5ms = 0°, 1ms = 45°, 1.5ms = 90°, 2ms = 135°, 2.5ms = 180°
  • 180° ultrasonic scanning avoiding: the ultrasonic sensor combined with a steering gear pan tilt that can rotate 180° can realize dynamic scanning and ranging in a large area ahead, judge the open position of the relative obstacle, and realize intelligent obstacle avoidance.

Yahboom SG90 9g servo platform with HC‑SR04 ultrasonic sensor mount for 180° scanning

Combine a 9g micro servo with an ultrasonic sensor mount to build a compact 180° scanning head for smart cars.

Micro servo platform illustrating 180° rotation range for ultrasonic obstacle avoidance scanning

The pan/tilt bracket lets the sensor sweep left to right for wider distance measurement coverage.

PWM pulse width chart mapping 0.5–2.5 ms signals to servo angles from 0° to 180°

PWM timing reference makes it easy to command repeatable angles across the full 0–180° range.
