BMW Factory Smart Transport Robot – Video
Plant Wackersdorf supplies the BMW Group’s international assembly and production sites with car parts. In the hall of Supply Logistics, a self-driving robot maneuvers itself underneath a roller container with parts. Silently and with flashing lights, it picks up the container and begins to move through the logistics hall. The system is complicated and extensive; nobody can find their way around without a good sense of direction. But this is no problem for the transport robot, which is about the size of a suitcase. Flanked by radio transmitters and equipped with a digital map, it drives independently to the destination of the goods. When tugger train cross its path, a fitted sensor identifies the obstacle and stops the self-driving robot with car parts loaded weighing up to half a ton.
In terms of smart logistics, the BMW Group is promoting innovative and trend-setting logistics systems: “The development of the Smart Transport Robot is an important milestone for the BMW Group when it comes to digitization and autonomization in production logistics. This innovation project makes an important contribution to the agility of the supply chain in Logistics and Production. It enables the supply chain to adapt to changing external conditions quickly and flexibly,” comments Dr. Dirk Dreher, Vice President of Foreign Supply at the BMW Group.
Measuring its distance to three radio transmitters allows the robot to calculate its exact position and route. With the help of sensors, it identifies critical situations and can respond accordingly, sharing the route with people and other vehicles. At a later point when the innovation is being implemented in series operation, a 3D camera system will make navigation even more accurate.
The transport robot will be able to function without the floor-mounted induction loops for navigation and will move freely within the space. The battery-powered radio transmitters mounted to the walls of the hall can be expanded to further areas in logistics flexibly without major effort and at low costs.
For the BMW Group, a self-driving robot tailored to meet the demands of the company’s supply logistics and production supply is a top priority. Besides custom-fit measurements for the containers to be transported, the vehicle also has sufficient battery capacity as the developers have drawn on the experience gained with BMW i: batteries previously fitted in BMW i3 vehicles are being sustainably reused. This BMW i3 battery module will provide eight hours’ worth of energy, covering a full shift.
