This complete component pack makes it easy to teach and learn how robots sense their surroundings. Students experiment with ultrasonic ranging to implement obstacle detection, collision avoidance, and simple mapping — core skills for autonomous robotics.
Designed for STEM classrooms and R&D labs, everything comes neatly organized in a plastic storage box. Developed by RoboRider Labs, trusted by educators and engineers for reliable, classroom-ready hardware.
Quick Project Ideas
Parking assistant: beep faster as objects get closer.
Avoidance bot: steer away from obstacles using distance thresholds.
Distance logger: record measurements to the serial monitor or LCD.
Tip: Mount the sensor at the front of the robot and keep it level with the ground. Use simple averaging or median filtering to smooth noisy readings.
Warning: Avoid soft, angled, or sound-absorbing targets — they can reduce echo strength and measurement reliability.
