I am augmenting my expertise by learning topics in control systems and electronics to place myself in a position to make contemprorary autonomous robots.
Sunil Kumar Singh is working on design of bamboo based linkages. Problems being addressed include minimization of lateral sway.
Sailen Dutta is working on study and implementation of nodal discontinuous finite element method. He is being co-advised with Prof. Anoop K. Dass, IIT Guwahati.
Sameer Tadavi is working on prototype demonstration of instability in trailers. Numerical simulation of instability is also planned to be undertaken.
Sooraj Chackao worked on design of a simple haptic robot. Finite element model of a virtual object was interfaced with a 2-R robot. Visual feedback was successfully demonstrated. Force feedback and related torque control of motors is pending.
Ravikumar and Saanwra Khod are working on algorithms and its hardware implementation for autonomous navigation of a wheeled vehicle.
Independent workRohit Suresh Murthy and Aniriddh Yadav are studying path-planning strategies for autonomous robot and implementing it in virtual situations.
Independent workT.Sai Kishore and V Chandrasekhar are aiming to fabricate six-legged parallel manipulator. The also aim to fabricate parts by 3D-printing.
Ronit Shaw worked on modelling and simulation of full-ground-vehicle spatial dynamics.
Naman Kansal and Lokesh Kumar Deswal worked on non-linear modelling and simulation of quarter car suspension.
Sudhansu Kumar Behera and Zubin Priyansh worked on simulation of robot in ROS (Robot Operating System) and dealt with issue on path-planning and vision. Zubib Priyansh also worked on restoring functionality of an old robot.
Independent workFollowing are some of the applets that I made in Geogebra as an aid for teaching ME224: Kinematics of Machinery in IIT Guwahati.
Instructions: Slide the green colored "theta" button to see the motion of both elliptic trammel and its inversion, Oldham coupling.
Instructions: Perturb I01, the red colored point to visualize finding I14 as a limit. The limiting concept is necessary when following sequence of finding instantaneous centers is adopted: I12, I42 and I41.
When I41 is found in the following sequence: I12, I30, I31 and I41, no limiting concept is necessary. Both the sequences lead to the same I14.
Instructions: Move the green slider to change the configuration of the four-bar linkage. A1-B1, A2-B2 and A3-B3 are the three specified positions of the coupler. Points A and B are also specified to serve as circle point of the four bar linkage. In the synthesized four-bar linkage two branches, "blue" and "green" can be identified. It further appears that "green" branch can take coupler to first two positions whereas "blue" branch can take to third position. However, with the four-bar linkage being a non-Grashof linkage, the two branches can flip over each other at singular configurations. Thus the synthesized four bar linkage can take the coupler through all the three positions without disassembly.
Instructions: Move the green slider to change the configuration of the four-bar linkage. A1-B1, A2-B2 and A3-B3 are the three specified positions of the coupler. Points A is to serve as a circle point of the four bar linkage. POint C at the origin is to serve as a fixed point. The synthesized four-bar linkage wht two branches, "blue" and "green" demonstrate the same characteristic as the previous example.
Instructions: The four green sliders are used to move 1) two points on two involute curves and 2) the rotate the involute curves about their respective centers of base circle.
