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 ... [More] 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.

This is a C++ implementation of the concept of Neural Cryptography, which is a communication of two tree parity machines for agreement on a common key over a public channel. This exchanged public key is utilized to encrypt a sensitive message to be transmitted over an insecure channel using Rijndael ... [More] cipher. This is a new potential source for public key cryptography schemes which are not based on number theoretic functions, and have small time and memory complexities. This is a proof-of-concept demo of how such a neural key exchange protocol in conjugation with AES encryption can be implemented in C++, which could be further extended in higher-level applications. Both CLI and GUI implementations of the software were created using Visual C++ (.NET framework). [Less]
