The AMM headquarter is currently located at the Department of Engineering Design, IIT Madras. A new set of office bearers have taken charge of the affairs of AMM. AMM invites both individual and corporate membership from Indian academia, research organizations and industry. Membership benefits and other information about AMM are available at www.ammindia.org. The body of Zonal Vice Presidents (ZVPs) is active over the past several years with representations from the four corners of the country. They are playing the role of nodal agencies so as to decentralise the AMM official activities and to organise workshops under the aegis of AMM to popularise the mechanism science in their respective regions. They also form the editorial team of this news bulletin. AMM invites contributory articles from its members and others working in the various fields of mechanisms science for this quarterly news bulletin. Interested people can contact the editorial team.

Conclusion A 6m aperture Unfurlable antenna has been successfully deployed in maiden attempt. In-orbit testing of the reflector has been satisfactory and meets all requirements. The development of UFA involves various domains of engineering like mechanism, thermal, structure, electromechanical, manufacturing, electrical, communications, etc. References [1] G. Roederer and Y.

Mechanism for Biologically Inspired Four Legged Robotic Vehicle

Riyaz Rafique1, Sumit Kumar2, Sri Narayan2 and Kamod Kumar Sah2

1Assistant Professor, 24th Year Bachelor of Engineering Student Department of Mechanical Engineering, School of Engineering,

Sri Satya Sai University of Technology & Medical Sciences, Sehore, M.P. Mechanism for biologically inspired four legged robotic vehicle is a newly fabricated linkage based parallel mechanism for legged locomotion. As the name suggests, the leg mechanism is inspired from the prior work “Adjustable mechanism for walking robots with minimum number of actuators”, authored by Professor Anirban Guha and Professor C. Amarnath. The leg mechanism is a single degree of freedom mechanism which is a combination of Hoecken mechanism and a parallel mechanism, here parallel mechanism is deployed to trace the same curve traced by Hoecken mechanism. In this project there are two actuators for powering four legs. One actuator is responsible for powering the two legs in left side and other actuator is responsible for powering the two legs in right side. The cranks of front leg of right side and rear leg of left side are parallel and in the same way the other two cranks are parallel but are at about 180 degree with respect to the first two cranks for moving forward or backward. The primary motivation behind this new design was to develop a biologically inspired four legged vehicle with only rotary joints and utilizing least actuators. The initial modeling of leg mechanism was done in AutoCAD and then the further dynamic simulation was verified by Autodesk Inventor 2015. After verifying the prototype of leg mechanism a low cost prototype of the robot was fabricated. Students have learned about real application of mechanisms during this project and have learned the concerned softwares. They are inspired and committed to work further in the field of mechanisms and machines with greater enthusiasm. This model had bagged first prize in a national level technical festival "Technospark 2k16”, held at Sri Satya Sai University of Technology & Medical Sciences, Sehore, Madhya Pradesh in the event "Robomania”, a robotics competition held on 25-26th April, 2016. In the event Robomania any robot with the best feature was decided to be winner. A fully functional prototype was demonstrated at the event. The low cost prototype was manufactured at the Sri Satya Sai University of Technology & Medical Sciences, Sehore, Madhya Pradesh. The students and the mentor acknowledge the help from SSSUTMS, Sehore, Madhya Pradesh thankfully. Figure 1 is a front view of single degree of freedom leg mechanism in which grounded link is shown in black, crank is shown in red and leg is in magenta. Foot trajectory of this leg mechanism for one complete rotation of crank is shown in cyan.
