What is Obstacle Avoiding robot?

Obstacle avoidance robot is design to allow robot to navigate in unknown environment by avoiding collisions. Obstacle avoiding robot senses obstacles in the path, avoids it and resumes its running. We have make use of sensors to achieve this objective. We have used two D.C.MOTORS i.e battery operated motors.

How do you make an obstacle avoiding a robot?

What sensors are used in obstacle avoidance?

IR sensors are widely used for measuring distances, so they can be used in robotics for obstacles avoidance. IR sensors are also faster in response time than ultrasonic sensors [17]. In addition, the power consumption of IR sensor is lower than ultrasonic sensors [11].

What is obstacle avoidance algorithm?

Khatib introduced an algorithm called APF in 1985 [6]. This algorithm considers the robot as a point in potential fields and then combines stretching toward the target and repulsion of obstacles. The final path of the output is the intended path.

How do robots detect obstacles?

The robot navigates without knowing a detailed map of the surroundings. If an obstacle is detected in its path, the robot adapts its velocity in order to avoid the collision. If the surrounding environment is free of obstructions, the robot simply moves forward until an obstacle is detected in the range of the sensors.

How do drones avoid obstacles?

Almost all of the drones made by DJI have an obstacle avoidance system enabled by technologies such as infrared sensors, stereo vision sensors, ultrasonic sensors, and GPS. These sensors work together to make sure the drone detects and avoids obstacles in the flight path to prevent crashes.

How does DJI obstacle avoidance work?

How do I make an obstacle detector?


  1. Connect one GND pin of Arduino Nano with the GND of HC-SR04.
  2. Connect 5V of Arduino Nano with the Vcc pin of HC-SR04.
  3. Connect echo pin of HC-SR04 to the D3 pin of Arduino Nano.
  4. Connect the trig pin of HC-SR04 to the D2 pin of Arduino Nano.
  5. Connect D12 pin of arduino Nano to buzzer’s negative pin.
