Image Motion Capture Facilities

Motion Capture Facilities

Large experimental room equipped with an optoelectronic Motion Capture System to compute the position of reflective markers, force plates embedded in the floor to measure ground reaction forces, 6-axis force sensors to measure additional force contacts, wireless EMG to measure the activity of muscles. The system is provided with a processing software to reconstruct the whole-body dynamics and identify key elements of the musculoskeletal activity.

Key features:
  • 16 wireless EMG sensors
  • Ergocycle Lode excalibur with six cells sensors at the handlebars, the seat and the pedals
  • 2 additional 6-axis force sensors to record additional contact forces (e.g, at the hand)
  • Two force plates embedded in the floor to measure ground reaction forces
  • 14 High resolution infrared cameras providing accurate positioning of reflecting markers
  • Isokinetic ergometer Biodex to quantify mechanical joint power, torque and/or velocity
Possible applications:
  • Transfer of human movement to humanoid robots
  • Motion Ergonomics
  • Human Motion analysis and Biomechanics
  • Robot localization and state reconstruction
  • Virtual reality
