paradigm that, in contrast with exact constraint design principles, makes deliberate and effective use of redundant constraints to improve performance and robustness. Design and Fabrication of Radio-Controlled Cars This was a fun course project for MIT's Design and Manufacturing Course. Here is a report with some cool pictures. These mechanisms are of importance to macro and micro scale precision positioning applications, including mems sensors and actuators, optical imaging, and semiconductor fabrication. While successive single axis mirrors may be used to steer the beam along multiple axes, a single two-axis mirror provides a simpler, more compact and inexpensive alternative. Slocum and his essay taj mahal india former graduate student Roger Cortesi have developed an integrated actuator and bearing system called Axtrusion.
PZT electrodes are employed to excite the structure at the frequencies that correspond to its two desired natural vibration modes. Click here to access papers and patents resulting from this work. Back to Introduction Page Maintained by Shorya Awtar, 2007. I helped in the detailing and layout of a precision grinding machine that Prof. A simple fabrication process flow allows for mass report writing model production of the device. My team was placed second in this competition. The reader is welcome to browse through this page and offer any thoughts / suggestions /criticism on the work by sending an email. . Planer multi Degree-of-Freedom Flexure Mechanisms, this work presents a new class of parallel-kinematics flexure mechanisms that have multiple degrees of freedom and substantially small error motions. Teams of students were required to design RC cars for mass production, and then fabricate half a dozen identical vehicles. 3-470, Cambridge, MA 02139 e-mail: Kevin. Analysis and Synthesis of Precision Flexure Systems.
In all these applications micro-mirrors are employed to steer a beam of light. Patent applications based on the above disclosures are currently being prepared for filing and a paper on this work is available on the publications page. The following documents provide further details. Craig, department of Mechanical, Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, 110 8th Street, Troy, NY 12180 e-mail. Some features of this site may not work without. My prime contribution to the project was design of a neat, yet extremely simple, suspension mechanism based on leaf springs made from spring steel.
