A vision guided robot is a robot fitted with one or more cameras used to analyze, inspect images, and provide secondary data signal to the controller. These robot systems are rapidly changing the production process, as they enable the adoption and implementation of robots into the system. The rapid change will also decrease the cost and complexity of fixed tooling in setting up of robotic cells.
The vision guided robot system comprises a camera and a computer. These robots primarily capture images and transfer them to the processor, which then reports the data. This system can be implemented in any industry for any purpose, as it aims to perform a variety of different tasks.
Conventional robots were used to simply pick and place objects, while with the advancement of technology in the areas of sensors, cameras, and computing power, the present-day vision robots are more efficient with improved quality and better functionality. Introduction of 3D cameras in these robots can be a great opportunity to the manufacturers. The advantage of 3D cameras over the previously used sheet-of-light triangulation is that it does not require the relative motion between the sensor and the camera. This helps in fast generation of 3D imaging with better accuracy. In addition, there is scope for robots to be upgraded so as to integrate the high resolution cameras which are available in the market for better imaging.
The major limiting factor for vision guided robots is the malfunctioning of the cameras and the lack of knowledge of robot operators. This can lead to huge damage to the machine, as well as the market. Other possible restraints are the restrictions to select the available camera versions with different resolutions. Enhancement of the robots is very limited in respect to the enhancement of cameras in the market.
The vision guided robot systems market can be segmented by end-use, and by geography. The end-use industries of vision guided robots can be further segmented into industrial use and non-industrial use. Industrial use covers industries such as automotive, semiconductors, pharmaceuticals and cosmetics, medical devices, and food among others. The non-industrial users are military and defense, security and surveillance, medical imaging and lab automation, traffic management and road safety among others.
The global market can be sub-segmented based on geography into North America, Europe, and Asia Pacific. Presently this market is dominated by the Asia Pacific region, followed by North America. Asia Pacific is also the fastest growing market in the world of vision guided robots.
The key vendors of the market are ABB Ltd. (Switzerland), Cognex Corporation (U.S.), Teledyne Technologies Internationals (U.S.). Other prominent vendors in this market are MVTec Software GmBH (Germany), Isra Vision (Germany), and Adept Technologies (U.S.).
