A vast range of human-friendly interactive robotic heads is being developed by researchers. However these robot heads require improvements in construction and behavior to achieve more human-like performance. Therefore this paper proposes a design of a robotic head with human-like movements. The details of the kinematic analysis, particulars on mechanical design of the neck, the electrical and control system of the robotic neck are discussed. The design parameters have been identified by analyzing the bio-mechanical information related to basic head movements of the humans. This paper includes a way to imitate human neck movements of flexion and lateral flexion. Design of this robotic neck platform is done in such a way that it can be used as a platform for facilitating further developments in integrating more additive features to a robotic neck, which are to be incorporated as per needed by any developer.

In deploying a large scale wind power plant, there are several aspects that have to be assessed. Among them the initial site screening for wind power plants, wind data assessment and proper selection of wind turbines are vital for the success of the project. This paper presents a step by step analysis in selecting a wind turbine, as a case study for Sri Lanka, where it has a substantial amount of wind energy that can be harnessed for power generation. Mannar area is identified as the candidate site with the high wind potential it exhibits throughout the year. After a detailed analysis of the wind resource in Mannar area, Gamesa-114 2 MW wind turbine is selected as the most suitable wind turbine for this particular area of Sri Lanka.

This paper focuses on designing and simulation of an interactive robotic arm for pick and place and service applications. The robot is expected to have image processing and voice recognition capability. The mechanical structure is simulated using forward kinematics and for this, Denavit-Hartenberg parameter method is used for the proposed design and hence the mechanical structure is simulated in MATLAB and SolidWorks. SolidWorks structure comprises the proposed link lengths and joints which were used for forward kinematics calculations and workspace simulations. Static and dynamic torques are taken into consideration to determine the torques of joint motors. It is expected to find the design requirements and assess the scope of the robot arm before its manipulation.
