Product Description The RedBot Sensor – Mechanical Bumper is a simple yet effective contact-based collision detection sensor designed for robotics projects. It uses a mechanical switch to detect when a robot has hit an obstacle, providing a digital signal output that can be easily read by Arduino, ESP32, STM32, or Raspberry Pi. This sensor is part of the RedBot robotics system but can also be used as a standalone module in DIY and educational robots. With a compact design, easy mounting holes, and reliable operation, it is ideal for robot navigation, obstacle detection, and bumper-style safety systems. Available in Bangladesh from PowerMark Solution, this module is a beginner-friendly and cost-effective way to add collision detection to your robot.
