Exosuits already assist in tasks, but they reach their limits in the complexity of everyday life. CISPA researcher Julian Rodemann, together with colleagues from LMU Munich and Harvard, is developing a machine learning approach that finds personalized settings and explains them. cispa.de/en/exosuits
Explainable AI Makes Exoskeletons Understandable—and Ready for Everyday Use
Exoskeletons are often seen as future tech, yet already reduce physical strain in logistics and manufacturing. But real-world demands are complex. CISPA researcher Julian Rodemann, with LMU Munich and...
