....harness. An exact explanation for the fractional force based on a mechanical analysis awaits future analysis. An application of these results besides virtual reality is in the use of treadmills for legged robot research. For example, treadmills have been built for the running robots of [6] and [5]. Our results suggest that slopes could be simulated for the running robots by adding an active mechanical tether. In addition, the mechanical tether could supply realistic inertial forces to those robots [1] Acknowledgments This research was supported by NSF Grant IIS 9908675 and by NSF Grant ....

....The original Sarcos Treadport. 2.1 Inertial Force Display Constant velocity locomotion on a treadmill is indistinguishable from constant velocity motion on a stationary surface of similar characteristics. However, when a user accelerates to a run, the physics of treadmill locomotion is different [13]. When the user moves forward, the belt moves backward an equal amount to keep the user centered. This belt motion imparts an inertial force to the user, which assists the runner and causes considerably less energy expenditure. It has been shown, for example, that 35 less energy is required in a ....

....a treadmill is indistinguishable from constant velocity motion on a stationary surface of similar characteristics. However, when a user accelerates to a run, the physics of treadmill locomotion is different, because the belt is servoed to center the user and applies an inertial force to the user [10]. This inertial force assists the runner and causes considerably less energy expenditure. In the Sarcos Treadport the linear axis of the mechanical tether is actuated and can push or pull on the user. This capability is employed to exert a force that counteracts the inertial force from the belt, ....
