TECHNOLOGY

SKILLS

Engineering Softwares: Solidworks, Creo, AutoCAD, Catia V5 Programming Languages: Matlab, Python, C++, LATEX. EXPERIENCE Summer Internship June 2017 - August 2017 BL Companies, New York

Worked under the supervision of a projectmanager and senior designers towards project goals.

Extensively used AutoCAD for structural designs and layouts in a constrained time frame.

Reviewed designs and brainstormed on improvements considering design crite- ria.

On site inspections of design criteria ful llment, survey and conceptualization.

Performed non-routine work like ling New York building department forms

(ex. TR1, PW1) and record research of subsurface utilities. PROJECTS Design projects at BL Companies, New York.

Design and drafting of an underground vault with a submersible pump for an M&R station at Staten Island, NY, required to drain out water from the electric conduits.

Cable tray design which required selection of brackets, ladder, splice plate and other parts according to the design catalog.

Slit trench design for National Grid for regular inspection of gas pipelines along the LI expressway.

3D modelling of a troughed belt conveyor for bulk material transfer under Dr Siddhartha Ray, Heritage Institute of Technology.

Detailed design of a 15 metres long industrial troughed belt conveyor according to the standards in the manual of Phoenix conveyor belt systems.

Part modelling and large assembly using Solidworks for generating 3D model and 2D drawings of the system.

Initial considerations like bulk material type, capacity, disposition angle were taken to calculate design parameters like belt tension, belt speed, pulley speci- cation and motor power.

Design and fabrication of a hydraulic press at Heritage Institute of Tech- nology.

3-D modelling of the product in CATIA and creating a BOM according to the design calculations for a 1 ton hydraulic press.

Fabrication of the press using lathe, shaping, milling, drilling machines.

Testing for an optimum output for deep drawing operations. Motion planning of a robot manipulator with complementary-based colli- sion avoidance under Dr Nilanjan Chakraborty, Stony Brook University. Thesis title- Geometric Motion Planning with Complementarity-based Motion Pre- diction and Collision Avoidance

Kinematic modelling of serial chain robot manipulator performing tasks in a cluttered environment.

Collision avoidance using complementary based algorithm which prevents pen- etration of robot arm in obstacle by using compensating velocities thus gener- ating collision free trajectory.

Modi cation of sampling based planner, RRT, to make the robot plan a collision free trajectory by discrete searching in con guration space.

Simulating a 7 DOF robot to achieve tasks imitating book shelving in 3 dimen- tional space with obstacles.

Analysis of 6-DOF motion in Stewart platform with PI controller under Dr Dipankar Sanyal, Jadavpur University.

Kinematic modelling of 6 DOF parallel robot manipulator, Stewart platform, with low-cost proportional valves .

Using Labview the algorithm was tested on the manipulator for verifying real time error in trajectory while performing various motions. CERTIFICATE Diploma in product design certi cation from CADD Center. PUBLICATION Analysis of 6-DOF motion with PI controller in electrohydraulic Stewart platform.
