Simulating Walking on Surfaces of Different Compliance using the ASU Variable Stiffness Treadmill

Health icon, disabled. A red heart with a cardiac rhythm running through it.

This research is being conducted to prove that the Human Oriented Robotics and Control Lab’s variable stiffness treadmill (VST) is capable of replicating the surface compliance of various walking terrains. Using IMU’s and a marker system built into the VST, it is possible to quantify a walking surface by leg deflection. Varying parameters on the VST, such as position of the stiffness device and speed, makes it possible to produce the same leg deflection profiles quantified in outdoor testing. Working to discover how the VST can simulate outdoor walking terrain is essential both for indoor rehabilitation, and prosthetic development purposes.
