There is an existing location aware audio travel system which uses GPS to tell the location of the listener. But GPS is proved to be extremely inaccurate which can cause trouble to the tourist. The proposed system is divided into two parts: The moving robot and a RFID communication. The moving robot scans the QR code through the RaspberryPi Picamera and follows it. If a human carries the QR Code, the robot will follow the human to any location.The second part uses Radio Frequency Identification (RFID) integrated which relies on Radio Waves. Each location or artifact is embedded with a NRF24L01 module, which is a radio frequency transceiver, that acts as a transmitter, and the robot acts as a receiver. Each module sends a unique radio signal. Based on the signals received by the receiver unit relevant information such a text, image, audio can be delivered to the user. In addition to an audio tour guide we also believe it is necessary to maintain a log of every individual who enters a designated area that is part of the tour. To maintain these logs, we propose using NFC sensors linked to a specified server that can be accessed whenever required.

ALU consists of many computational units like adders, multipliers, logical units etc. Vedic Mathematics concepts are proposed here for designing the computational units of an 8-bit ALU. Here, a high-speed 8×8 bit multiplier is proposed which is based on the Vedic multiplier mechanism. A divider based on vedic mathematics is also proposed here. The proposed Vedic mathematics based ALU is designed using high level hardware description language-Verilog, followed by synthesization using EDA tool, Xilinx ISE 14.1. Finally, the synthesized circuit has been implemented on Xilinx Spartan-6 Field Programmable Gate Array (FPGA) device.
