A new software and hardware complex that allows controlling a robotic arm using signals from the user's brain has been developed by scientists at Novosibirsk State Technical University (NSTU). The new technology aims to help people with disabilities.
The interface for interaction between the human brain and the device converts brain signals into commands for controlling computers and prostheses.
The developed complex combines all the necessary stages: from registering signals using a headset to analyzing brain reactions, creating an individual user profile, and setting up photosimulators to optimal frequencies. The next step will be to recognize commands in real time and transmit them to control robotic devices.
Senior Lecturer of the Department of Data Acquisition and Processing Systems at NSTU, Alexey Kozin, explained that the system is based on steady-state visually evoked potentials (SSVEP), which appear when looking at flickering light sources. The system reads these signals and converts them into commands for control.
During the project, a photostimulator was also created — a device with flickering LED panels, each of which operates at a specific frequency. Concentration on one of the panels causes the desired response in the user's brain. Special software allows you to adjust the frequency and brightness parameters for each person. A control unit was also developed for a robotic manipulator arm, which executes commands received through the interface.
