At a joint stand of the European research initiative SMErobotics, scientists from Fraunhofer IPA will demonstrate a sensor-controlled lightweight assembly robot that allows the high-quality, profitable automation of previously manual assembly processes, especially in the small-scale production sector.
The focus is on effective human-robot interaction at a workstation similar to those on a shop floor, the goal being to enable the worker to easily program the robot and use it intuitively like a tool.
Growing cost pressure, short product life cycles and high product diversity call for flexible and cost-effective assembly systems that can be quickly adapted to suit changed requirements. Scientists at Fraunhofer IPA have developed a sensor-controlled assembly process that makes it possible for workpieces to be localized and positioned.
Work-holding fixtures are extensively replaced by sensors, this offering flexibility at low cost. Other advantages are that the robot is designed to be easily programmable and capable of dealing with tolerances.
Using a robot as a tool
“Our aim is to demonstrate that sensor-controlled robots are capable of coping with modern-day conditions at manual assembly workstations, such as chaotically arranged components,” says Martin Naumann, Group Leader in the Robot and Assistance Systems department at Fraunhofer IPA. The emphasis is on effective human-robot interaction. Selected assembly processes are carried out manually, while others are automated. The robot is intended to be used as a tool.
At the joint stand of the European research initiative SMErobotics, Fraunhofer IPA will demonstrate sensor-controlled assembly in a robot cell with the KUKA LBR iiwa. “At a manual workstation, we’ll use the lightweight robot to carry out riveting processes as an example.
However, the underlying concepts can equally well be applied to other assembly processes,” explains Naumann. The components are made available within the robot’s working area without the need for any separate work-holding fixture.
The robot moves to the determined location and localizes the exact riveting position on the component using a stereo camera integrated in the robotic tool. “We’re highly interested in transferring the exhibited solution to new applications – especially at small and medium-sized manufacturing enterprises, where manual work processes prevail,” says Naumann.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
