When Robots Know What to Reach for - Contact-Based Motion Planning

28. Mai 2020

Bild

We all tried to navigate in a dark room in the middle of the night. Even when we know the room, it is challenging because our visual perception is high uncertainty. Uncertain perception and motion make motion planning an even harder problem. But reaching out to the wall to guide our hand is a simple and robust way because contact not just reduces uncertainty in our location. mehr zu: When Robots Know What to Reach for - Contact-Based Motion Planning

Human-Like Grasping With Robot-Like Reactiveness

28. Mai 2020

If we want robots to help with daily chores, first they need to interact with their environment physically, and second, these machines need to accept their imperfection both in their motion and perception. This is a difficult problem because modeling the environment and dynamic interactions are either a weak approximation or too complex to plan robustly or efficiently. mehr zu: Human-Like Grasping With Robot-Like Reactiveness

Leveraging Data from Mass Spectrometry to Improve Cross-Links

Bild

Cross-Links are experimentally derived distance constraints that can be used to guide protein structure prediction. The current cross-linking data is obtained from multiple mass spectrometer runs and pre-filtered. In the pre-fltering step we lose a lot of information. For instance, there is ambiguity in the data that is currently handled in a greedy fashion. The idea of this project is to go one step back and look at the "raw" data from the mass spectrometry experiments. The hope is by including external information and dealing directly with the ambiguity in the data we can improve the number of cross-links and/or need fewer experiments for a similar yield. mehr zu: Leveraging Data from Mass Spectrometry to Improve Cross-Links

Leveraging Crosslinks for Template Retrieval

Bild

Cross-Link Mass Spectometry is an experimental technique that provides residue distance constraints on the native structure. The method has been previously used to guide ab initio protein structure prediction. You will develop in this thesis a method that leverages cross-links to find homologous structures to the target in the PDB. For that, you will compare the distance constraints provided by cross-links with simulated cross-links for the templates from the PDB. mehr zu: Leveraging Crosslinks for Template Retrieval
