How do obstacle avoidance sensors work?
Obstacle avoidance sensors usually work with the help of infrared waves that are emitted and received by the sensor. Here’s how they typically work:
- The sensor emits infrared waves, which bounce off any objects in front of it.
- The waves are then received by the sensor and analyzed to determine if there is an obstacle present.
- If an obstacle is detected, the sensor sends a signal to the device controlling the sensor, such as a robot, to stop or adjust its course.
Obstacle avoidance sensors are used in a variety of products, such as robots, drones, and autonomous vehicles. The technology is constantly improving, allowing for better accuracy and faster response times.

Obstacle Types
| Obstacle | Detection Accuracy | Detection Range | Avoidance Strategy |
|---|---|---|---|
| Reflective surfaces (e.g. glass, mirrors) | Low | Short | Manual steering or Alternate Route |
| Thin objects (e.g. wires, branches) | Minimal | Inconsistent | Manual steering or Observe Carefully |
| Fast-moving objects (e.g. birds, cars) | Medium | Short | Slow down or Stop |
| Horizontal surfaces (e.g. water, sand) | Low | Short | Hover or Land Carefully |
By being aware of these limitations and taking proactive steps to mitigate them, you can enjoy flying DJI Mini 2 with more confidence and less risk. Keep in mind that obstacle avoidance is not a substitute for responsible flying and common sense. Practice makes perfect, so take the time to learn and master the drone’s features before attempting more challenging flights or maneuvers.

Environmental Factors
- Obstacle avoidance sensors may be affected by certain environmental factors, such as:
- Low light or glare: This can make it harder for the sensors to detect obstacles, especially reflective or shiny ones.
- Wind or turbulence: This can make the drone sway or tilt and reduce the accuracy of the sensors.
- Interference or obstruction: This can block the signals between the sensors and the flight controller, or create false positives or negatives.
Human Factors
- Obstacle avoidance features may also be affected by human errors or oversights, such as:
- Not activating or calibrating the sensors properly: This can lead to inaccurate or inconsistent obstacle detection and avoidance.
- Ignoring the warnings or signals from the drone: This can result in collisions or crashes that could have been avoided.
- Over-relying on the obstacle avoidance features: This can create a false sense of security and lead to complacency or carelessness.
What are the limitations for the obstacle avoiding robot?
- Obstacle avoiding robots depend on sensors, which can be limited in range and accuracy. This means that they may not be able to detect smaller, lower obstacles and may struggle to navigate in areas with poor lighting, reflective surfaces or cluttered environments.
- Robots that rely on infrared sensors may be affected by bright sunlight or other sources of infrared radiation which can interfere with the sensors’ signals.
- If the surface on which the robot moves has a lot of variations or unevenness, it may find it difficult to avoid obstacles effectively. In some cases, the robot may get stuck or topple over.
- Obstacle avoiding robots may also struggle with rapidly changing environments or obstacles that are moving quickly. They may not have enough time to react and avoid a collision.
