Andrew O Payne of LIFT architects and Jason Kelly Johnson of Future Cities Lab describe the Firefly plug-in for Grasshopper? they have developed, which extends geometric control beyond the virtual parametric model to the real world of machines and mechanisms. Firefly also enables communication to flow in the other direction, allowing virtual building models to be informed by, and interact with, data from the real world.

Undergraduate (UG) Research is the first step in a students' life to taste the experience of a research work. It is also a unique experience for the teachers to guide the students in research work during their UG study. In this paper we want to share our research experience through the project that involves the building of a Robotic arm which mimics the motion of the human arm of the user at Humanitarian Technology (HuT) Labs of Amrita. The system monitors the motion of the user's arm using a Kinect. The skeletal image of the arm obtained using the "Kinect Skeletal Image" project of Kinect SDK, consists of 3 joints and links connecting them. Coordinate Geometry is used to calculate the angles between the links connecting the joints. This gives us the angles for a 3D representation of the human arm. The angles thus obtained are sent using a serial communication port to the arduino microcontroller, which in turn generates signals which are sent to the servo motors. The servo motors rotate according the angles given as input. The combined motion of the servos results in a complete Robotic arm movement which is a mimic of the human arm movement.

Wireless sensor network (WSN) enhanced the process of monitoring many environmental phenomena such as the air pollution monitoring issue in proposed this paper. In this paper, a WSN based microcontroller equipped with gas sensors have been actively used for air quality monitoring. The design included several units mainly: arduino microcontroller, MQ-2 Gas Sensors, and the current regulator circuit. Based on the normal gas levels of the clean air, the obtained results indicate that there is a big difference in the gas levels of both gases (LPG and CO) which obtained from the several tests and circuit runs. However, the acquired results for the air quality control inside the KFU buildings show no risky situation to be considered for further actions. This work will apply the electrical engineering techniques as well as environmental engineering knowledge by using wireless sensor networks to measure Air Quality Parameters such as Carbon Monoxide (CO) and Liquid Petroleum Gas (LPG).

Human robot interaction is an issue mostly oriented toward service robotics but recently has a significant impact in the field of assembly applications. Assembly is a highly complex field where technical systems lack sophisticated human manipulation skills and possibilities. A simple capacitive sensor has been developed for aiding the human-robot interaction in industrial applications. The capacitive sensor consists of rubber foam with an embedded highly flexible metal mesh. The sensor is connected to an arduino controller and mounted on the robot. When the human operator is in contact or in close vicinity of the robot the change of capacitance is detected. The arduino controller sends messages through TCP/IP protocol to a FANUC LR 200iC 5L articulated robot arm controlling unit. The robot responds based on the input and is able to reduce speed or stop current movement and operation. A prototype sensor is described in detail and test applications are presented.

We describe and demonstrate an inexpensive, easy-to-build, portable spectrometer for nuclear magnetic resonance measurements in the Earth's magnetic field. The spectrometer is based upon a widely available inexpensive microcontroller, which acts as a pulse programmer, audio-frequency synthesizer and digitizer, replacing what are typically the most expensive specialized components of the system. The microcontroller provides the capability to execute arbitrarily long and complicated sequences of phase-coherent, phase-modulated excitation pulses and acquire data sets of unlimited duration. Suitably packaged, the spectrometer is amenable to measurements in the research lab, in the field or in the teaching lab. The choice of components was heavily weighted by cost and availability, but required no significant sacrifice in performance. Using an existing personal computer, the resulting design can be assembled for as little as US$200. The spectrometer performance is demonstrated with spin-echo and Carr-Purcell-Meiboom-Gill pulse sequences on a water sample.
