This is the largest robot in the history of Seat in Martorell




More than eight feet tall and three tons in weight. These are the dimensions of the new giant of Seat’s Martorell plant, the largest robot in the history of the factory, which joins the more than 2,200 that collaborate in the assembly of the latest models of the company. And the figures of this automotive tech giant are even more surprising than its size.

3,000 kilos of precision. Many of the pieces that make up the car puzzle alone weigh hundreds of kilos. When it’s time to assemble them, the weight multiplies. “In order to be able to transport and assemble the bulkiest parts of the car and for its structure not to suffer in the least, it was necessary to use a larger robot,” he says. Miguel Pozanco, Head of Robotics at Seat. With its almost three meters high, this robot is capable of assembling three of the heaviest parts of the vehicles, those that form the side, weighing almost 400 kilos.

Among 2,200. Martorell already has two units of these giant robots. They work in parallel in the sheet metal shop together with 2,200 others in the facilities as a whole, coordinated with 1,700 workers to manufacture the bodywork of a car every 68 seconds. Its incorporation simplifies part of the vehicle assembly process and reduces the space occupied by the manufacturing line. “These robots assemble fundamental assemblies of the vehicle, such as the sides. By being able to lift more weight, they carry out two operations at the same time, increasing the quality of the pieces ”, according to Pozanco.

Two and a half meters carrying 400 kilos. Seat has other robots that are capable of transporting up to 700 kilos, but in this case they needed to go one step further, exactly four meters more. “There is a relationship between the weight that the robot can carry and the reach. That is, it is not the same to hold a bucket of water with your arm next to your body than with your arm extended. This giant can transport 400 kilos almost four meters from its central axis ”, explains the head of Robotics at Seat. This is a great novelty, since the same robot joins the three pieces on the side and can move them to the welding area without any other robot having to manipulate them again. This has been achieved thanks to the incorporation of a linear axis that allows it to travel up to four meters.

Industry 4.0. The robots have software implemented that allows remote monitoring of all their operating data, such as motor consumption, temperature, motor torque or accelerations. «With the analysis of this data we can anticipate any unforeseen event. In other words, predictive maintenance is carried out, with which we manage to ensure quality and precision on an ongoing basis, ”concludes Miguel Pozanco.
