The Sarcos SenSuit simultaneously measures 35 degrees of freedom (DOF) of the human body. It can be used for real-time capturing of full body motion, as an advanced human-computer interface (HCI), or to control sophisticated robotic equipment.
The complete SenSuit is worn like an exoskeleton which, for most
movements, does not restrict the motion while an array of lightweight
Hall-sensors reliably records the relative positions of all limbs. For
the arms, we collect shoulder, elbow and wrist DOF, for the legs, hip,
knee and ankle data is recorded. In addition, the Sensuit measures
head as well as waist motion.
Our experimental setup for the SenSuit consists of a serial
connection to a computer to capture the data at a frame rate
of up to 100Hz. A platform independent OpenGL graphical display can
be used to simultaneously show the captured motion in real-time as
well as to generate and to play back animated sequences of stored data
files (see animated GIF image below).
Our primary interest is to study human motor-control, e.g. to analyze the unique data from the SenSuit in respect to certain task-related movements. One key question we seek
to answer in this context is how the human motor cortex efficiently
analyzes, learns, and recalls an apparently infinite number of complex
movement patterns while being limited to a finite number of neurons
and synapses. These preliminary studies will help to develop new
concepts for controlling humanoid robotic systems with many degrees of
freedom, one goal which has not yet been achieved by artificial neural
