The Department of Biomedical Engineering of the University of Florida is studying human brain activity while stepping over obstacles during walking or running.
Electroencephalography (EEG) is commonly used for static subjects but when it comes to mobile studies, there are a lot of artifacts coming from the motions. These artifacts hide the underlying neural signals of interest.

To better understand the human brain dynamics, the University of Florida (UF) wants to simulate human locomotion in order to first study how to improve EEG signal quality.
A phantom (fake) head will be installed onto the hexapod to measure the EEG artifacts linked to the EEG hardware. Several walking and running scenarios will be played by the hexapod.
Then, after eliminating the EEG artifacts thanks to hardware improvements, signal treatment, and data analysis, the Human Neuromechanics Laboratory of Prof. Dan Ferris at UF can concentrate on studying the brain activity signals.
Other studies using the hexapod will follow, such as testing robotic exoskeletons.
The dynamics of NOTUS P were not fast enough to mimic human motions, so we had to develop NOTUS V, a compact dynamic hexapod with higher velocity but less payload capacity.
