A robot fitted with one or more cameras used to analyze, inspect images, and provide secondary data signal to the controller more accurately is a vision guided robot. These robot systems are rapidly changing the production process as it enables 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 the images and then transfers it to the processor and finally reports the data. This system can be implemented in any industry for any purpose as it aims to perform a variety of different tasks.
The major purpose of vision guided robots is to reduce the manpower. The primary component of these devices are the cameras. Introduction of cameras in robots eliminated expensive fixtures as the cameras replaced the use of sensors such as proximity sensors which senses the presence or absence of objects or the distance between objects. Light sensors sense the presence, color, and intensity of light. The replacement of these sensors also reduced the cost of labor required to install the sensors individually. The integrated cameras in robots drives the vision guided robot systems market. These robots require very less guidance and thus reduces programming effort to a large extent as it can perform several tasks at a time. These robots are more flexible than the conventional robots as they can capture images in different areas from one point. Due to their increased flexibility, the speed of production increases with minimal error. Vision guided robots use cameras which reduces the cost of different sensors and makes these robots cost-efficient. Demand from different industrial sectors for these cost effective, more flexible, highly reliable robots that need less guidance, is expected to drive the vision guided robot systems market to a large extent in the near future.
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. Another possible restraint 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.
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 part. 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 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.). Few other prominent vendors in this market are MVTec Software GmBH (Germany), Isra Vision (Germany), and Adept Technologies (U.S.).
