Gait Phase Estimation and Foot Trajectory Prediction During Dynamic Walking Using Gated Recurrent Units
… field of assistive robotics and exoskeletons, foot trajectory prediction has the potential to play a pivotal role in improving the functionality and user experience of worn devices. Rather than operating as a reactive system which only responds to user movement, a de vice which predicts future …

Investigating age-related differences in visual sampling behaviour during adaptive locomotion and their consequences for stepping accuracy
… delayed gaze transfer from a target, their foot placement showed greater accuracy and consistency. Secondly, we investigated a possible relationship between increased anxiety about upcoming obstacles and early gaze transfers away from an initial target. We found that progressively increasing …

A Two-DOF Bipedal Robot Utilizing the Reuleaux Triangle Drive Mechanism
… utilizes the Reuleaux triangle to generate the foot trajectory to achieve a constant body height during locomotion while maintaining a constant velocity. By using a differential drive, the robot is also capable of steering. In addition to the analytical results of the trajectory profile of each …

Finger walking control of a two-dimensional walking model through inverse kinematics
… of a leg model in the sagittal plane. The foot position and angle were also very close to the actual foot trajectory, which was able to successfully drive the hip, knee, and ankle angles through inverse kinematics. This is an important step to one day have the control the FES stimulation of …

A novel approach to user controlled ambulation of lower extremity exoskeletons using admittance control paradigm
… employing admittance control by using hand-trajectory as a surrogate for foot trajectory. Preliminary study included subjects controlling the trajectory of the foot in a virtual environment using their contralateral hand. The study proved that hands could produce trajectories similar to …
