VoCoRoBo

This work is based on the implementation of real-time speech recognition using DSP algorithms such as Chebyshev IIR filters, accelerometer for tilt-sensing and establishment of short-range wireless secure link with ARC4 cipher, all using low-cost 8-bit ATmega microcontrollers. The robot implements a simple but effective algorithm for comparing the spoken word with a dictionary of fingerprints using a modified Euclidean distance calculation. It also includes the ability to securely control the navigation of multiple robots located at remote locations wirelessly from the Control Module and also gather the various environmental data collected by the Robot Modules and display them in the back to Control.
