MENTOR
Multimodal detection of the normal vector field of transparent objects for robots
PROJECT DESCRIPTION
ROBUST GRIPPING OF TRANSPARENT OBJECTS
MOTIVATION
Recent advances in artificial intelligence (AI) have expanded the applications of robotics beyond traditional areas like automobile production, leading to enhanced process optimization. With the potential for further scaling, these technological developments are poised to revolutionize industries such as chemical and optical. However, automation in these industries presents unique challenges due to the prevalence of glass components, for which a flexible industrial gripping solution has yet to be developed.
OBJECTIVE AND APPROACH
Current state-of-the-art technology is capable of detecting grasping points on glass bodies with a success rate of 72 percent (ClearGrasp, Google, Columbia University, ICRA 2020). The MENTOR project endeavors to improve this success rate to over 98 percent by developing and integrating a sensor head comprising up to seven sensors operating in diverse modalities into different overall systems. These systems will include an articulated robot-based laboratory automation system and an automatic optical component inspection system.
INNOVATION AND PERSPECTIVES
The main challenges lie in recognizing the contour of transparent objects and their position in space. In order to overcome these and other challenges, the following innovations are being pursued in the overall network:
Use of sensor technology in different wavelength ranges and modalities.
Data processing and fusion directly in the sensor head.
Creating open interfaces for use in robotics and beyond.
With this approach, a sensor system is to be developed that can also be used flexibly beyond the applications dealt with in the joint project.
OUR CONTRIBUTION
Our main focus is the development of a modular robotic system designed for handling glass vessels in laboratory settings. Our responsibilities encompass the creation of a data processing platform to facilitate value-added services, as well as the establishment and provision of standardized industrial interfaces for connecting the sensor head to the control level. Additionally, we will evaluate additional data processing concepts to leverage the data processing platform for value-added services.
