Downward-facing IR sensors can also be used to detect a "cliff," like the top of a set of stairs (a single step might not seem like a "cliff" to a human, but it does to a tiny robot!). Normally, the downward-facing sensors are very close to the floor, so the IR light is bounced back.

Feb 11, 2013 · The 1st ultrasonic sensor (Parallax) is used as an obstacle avoidance sensor. The second ultrasonic sensor (SR04) is used to check the ground distance so the robot won't fall into a hole in the ground.

Feb 19, 2013 · With the distance sensor you will need to check whether it is a digital or analogue signal provided by the sensor. For the purpose of your 'cliff sensor' you would probably be fine with digital as you would be able to use the sensor as a toggle to detect when the distance is over a minimum distance.

Sep 26, 2020 · A multi functional Arduino UNO based obstacle avoidance with Ultrasonic sensor and table edge detection using IR sensors.

Jan 10, 2021 · In an autonomous mobile robot, one possible way to implement cliff detection and avoidance is to detect cliffs using range sensors and to add the detected cliff data into the existing ROS...

This project uses the 8 inbuilt ultrasonic sensors and one additional ultrasonic sensor interfaced via Arduino Uno [Arduino Ultrasoninc Sensor HC-SR04] to detect objects and cliffs. The HC-SR04 sensor should be attached to the front of the robot via an extended rod and facing vertically down towards the floor.

Sensors The iRobot Create comes with some basic sensors mounted on its platform, they are: • 2 bump sensors (left, right) • 4 cliff sensors (left, front left, right, front right) • 3 wheel drop sensors (left, right, caster (center)) • 2 buttons (labeled advance and play)

Roomba is able to traverse floor with object detection. It is also has cliff detection to prevent a fall. Roomba will auto correct path and check distance with checkWall and will drive the direction with more space in a given room. Roomba also has an ardunio nano with a buzzer connected to play jingle bells as it drives around.
