In the industrial world and automation, the machine requires a sensor to give them the information needed to carry out the write operation. We can add many sensors to different robots to improve their adaptability.

We see many collaborative robots that have an integrated sensor and torque camera for having a better perspective on their operations and providing the safest workspace. This makes us think it will be a good thing to calculate different sensors integrated into robot cells.

2D Vision3D Vision.

2D is a vision video camera that can do many things. From detecting movements to the peonage of the part on the conveyor. 2D Vision has been on the market for a long time and here to stay. Many smart cameras out there can detect spare parts. And coordinate the section’s position for robots so they can adjust their actions with the information they receive.

3D Vision.

3D Vision is a much newer phenomenon compared to 2D Vision. A Tri-dimensional vision system must have two cameras at different angles or use a laser scanner. In this way, it can detect the third dimension of the object. Again many applications use a 3D vision. For example, BIN uses a 3D image to see things in a tray and re-create parts in 3D, analyze it, and take it in the best way.

The Vision gave the eyes to the robot, forcing the torque sensor to touch the robot wrist. Here the robot uses a style torque sensor (FT sensor) to determine the power applied by the robot with the tip of his arm. Most of the time, FT sensors are between robots and tools. In this way, all it applies the power to monitoring tools.

Power Limitations

Applications such as assembly, hand guidelines, teaching, and power limitations can be made with this device. What if you want to detect the style applied to the robot arm? For example, you want to know whether the robot is in a collision with something or someone? Well, the next type of sensor answers all these questions.

Collision detection sensor

Such sensors can have different shapes. Because the main sensor application provides a safe work environment for human workers, collaborative robots will most likely use it. Some sensors can be a tactile recognition system, where if the pressure is felt on a soft surface, the signal will be sent to the robot to limit or stop its movements.

You can also see this kind of sensor directly built into the robot. Some companies use accelerometers; some use current feedback. In both cases, when abnormal strength is felt by an emergency stop robot released. This provides a safer environment. Even though, before the robot stops, you will still be kicked by him. The safest environment is an environment without risk collisions. This is about the next sensor.

Safety sensor

With industrial robots’ introduction in collaborative mode, the industry must react by protecting its workers. This sensor can appear in many forms. From the camera to the laser, it designs the safety sensor to notify the robot that there is a presence around it. Some safety systems are configured to slow the robot after workers are in certain areas/spaces and stop it after workers are too close.

A simple example of a salvation sensor will be a laser on your garage door. If the laser detects obstacles, the door immediately stops and retreats to avoid collisions. This can be a fair comparison with what safety sensors in the robot industry.

Sensor detection section

For applications that require you to choose parts, you might not have a clue if the domain is on the gripper or if you miss it. Well, the detection section application gives you feedback on your gripper position. For example, if a gripper missed the GRAS operation, the system will detect an error and repeat the process to understand the region well.


Of course, they can install many other sensors on your robotic cells that are very specific to your application. The sensor capable of tacking stitches in welding operations is a good example where specific sensors are needed.

Tactile sensors are also becoming more popular today. Most of the time, this kind of sensor is right on the gripper to detect and feel what is in it. Sensors can usually see the strength and draw vector arrays with style distribution. This shows the right position and allows you to control the situation and power that grasped the final effector. Some tactile sensors can also detect heat variations.

Finally, the sensor is the major component to use the intelligence of the software. Without such sensors, sophisticated operation will not be possible. They bring a lot of complexity to surgery, but they also ensure excellent control during the process.
