While the race to level-5 self-driving cars continues to capture the public imagination, less is being said about the increasing automation going on behind the scenes.
Robots in automotive manufacturing is nothing new â General Motors was the first-ever company to deploy them back in 1961 â but their remit has exploded. Today theyâre driving optimisation and the rethinking of processes and production in innovative new ways.
Hereâs a quick guide to some of the top robotic tech shaking up the sector.
Tech 1: Collaborative robots (cobots)
What is it?
Designed to assist humans in mundane and strenuous high-precision tasks, cobots have a smaller footprint than existing production machinery and can learn through simulation rather than requiring programming. Thanks to sensors that react to human contact, they operate safely alongside workers on the same assembly line. Their strength, speed and force are also limited to avoid injury.
Whoâs leading the tech?
ABB, Rethink Robots, KUKA, Universal Robots, FANUC, Yaskawa
How will it change the industry?
- Allow more efficient, safer and flexible production lines
- Enable automation of increasingly complex tasks
- Lead to humans and robots working side-by-side
Tech 2: Automated guided vehicles (AGVs)
What is it?
AGVs are operator-free transport systems designed to move raw material and parts repetitively over short-to-medium distances. They use lines, tape or magnet infrastructure to travel from A to B. Sensor cameras are now being added to create vision-guided vehicles (VGCs). This evolution uses 3D map technology to navigate autonomously through crowded manufacturing plants.
Whoâs leading the tech?
Seegrid, Bastian Solutions, Transbotics, Daifuku, Axter, Indeva
How will it change the industry?
- Optimise workflow processes, increase productivity and reduce costs
- Improve workplace safety, replacing forklifts and other manual vehicles
- Enable increasingly flexible logistics and production layouts (VGVs)
Tech 3: Painting robots
What is it?
Automated painting is already standard practice in the automotive industry. Robotic arms spray the bodywork, removing the need for skilled manual painters and offering a smoother, faster, more even finish. Todayâs cloud-connected articulated-arm painting robots are lighter, speedier and equipped with numerous sensors and activators. Theyâre also easier to install and integrate.
Whoâs leading the tech?
ABB, Durr, KUKA, FANUC, Kawasaki, Yaskawa Motoman
How will it change the industry?
- Continue to improve final finish quality
- Make more customisation possible
- Reduce the need for human programming
Tech 4: Robotic vision
What is it?
Robot (2D and 3D) vision involves using a combination of camera hardware and computer algorithms to enable robots to process visual data from the world. Itâs used in a number of ways throughout the automotive supply chain. Its main applications are ensuring the quality of the end product and enabling robots to be flexible and adaptive in part-picking and logistics.
Whoâs leading the tech?
Keyence, Basler, Cognex, ISRA Vision, Omron Adept Technologies
How will it change the industry?
- Boost productivity through flexible, complex process automation
- Lead to great demand for automated maintenance and inspection
- Make human-robot interaction in production safer
Tech 5: Automated welding
What is it?
Welding robots have been used in automotive manufacturing since the 1980s, traditionally for spot and arc welding. Todayâs smart six-axis robots are becoming increasingly flexible and precise. Theyâre able to perform a range of welding techniques from laser to friction. Welding automation is also going one step further, metamorphosing into complete bodywork solutions.
Whoâs leading the tech?
Yaskawa Motoman, Comau, Kawasaki, KUKA, ABB, FANUC
How will it change the industry?
- Improve welding quality, enabling material efficiencies and lighter cars
- Increase the speed of multi-material vehicle production
- Make production facilities safer, more flexible and streamlined
Robots have and will continue to drive efficiencies and cost savings in the automotive sector, as more and more processes become automated. At the same time, increasing flexibility in production will become possible â meeting todayâs demands for customisation and the new era of automated cars.
