    ABSTRACT: The project here is a creation of a solar light following and an obstacle avoiding robot without the use of any complex units like microcontrollers. The control circuit of the robot is designed making use of analog and digital properties of NAND and NOR CMOS IC’s. The robot is powered by solar cells and uses power in microwatts for its functioning, making it very efficient in terms of energy. It follows a bumblebee way of locomotion, making it very effective in obstacle aversion. It is seen that this robot is more efficient than any other solar light follower available currently.

    ABSTRACT: Code injection attacks are a very common phenomenon in the computer world today but it has been a common belief that such attack is impossible on Harvard architecture CPU core design. Harvard architecture is majorly used in the sphere of embedded systems. This paper presents an implementation of code injection attack for a wireless sensor network by exploiting the program vulnerabilities and tests further possibility for the creation of a worm. We show a permanent code injection into the program memory of an AVR based sensor network and gain full control of the target sensor. Our attack combines different techniques such as return oriented programming and fake stack creation and injection. We present the various execution details and some counter-measures for its prevention. Previous work only succeeded in injecting data or performing transient attacks but this is the first result that presents a permanent code injection in Harvard architecture devices.

    ABSTRACT: The Plasmodium of Physarym polycephalum has been studied inthe biological and engineering community as a potential biologicalsubstrate which is capable of exhibiting properties concerningparallel and concurrent computation .several experiments haveshown its capability to optimize graphs and combinatorialgeometry. In this paper, we propose the utility of this plasmodiumcomputing, in minimum resistance surface like water, basic treestructures and manipulation of light objects. We further speculatethat the results of these experiments can help create biologicalamorphous robots.
