BCI update with alpha trigger for hand grip action
04/19/2019 at 03:32 • 0 commentsFirst attempt of controlling the prosthesis with brain signal. The test is simple alpha trigger, using alpha signal to close and open the hand with a predefined grip pattern.

Fast active vision system developed for prosthesis
04/19/2019 at 03:25 • 0 commentsThe following video shows the hybrid active vision system designed for this prosthesis. This system consists of an object tracker and an object recognition system that finds an object of interest, chooses the most appropriate grip pattern and waits for the user consent before attempting to grab the object. While the user moves closer to the object, the wrist will be calibrated.
This is the first endeavor to create the real-time tracker for the next step.

Processing application to control prosthesis
04/19/2019 at 03:20 • 0 commentsAn application is written to control the prosthesis from a PC. User could control the prosthesis by changing an animated arm on screen. The prosthesis will then be updated with new data through serial communication and calibrate itself.
The application is written using Processing and Python.
The purpose of this application is to either:
- Support the user with another interface to debug the prosthesis, or practice using the prosthesis without damaging the mechanical parts (when practicing using EMG and brain-computer interface.)
- Support the user with an interface to embed the prosthesis with more grip patterns in the future easily.

First design of the prosthesis
04/19/2019 at 03:16 • 0 commentsFirst design of the prosthesis with only 8 DOF. This design is frail and does not have high dexterity.
This design does not have wireless support, everything is controlled using a built-in serial controller.
