Software Used

TK Solver: This solves a set of linear/non-linear algebraic equations. Here, you write the equations as it is derived. No need to write the output in the left hand side, as in conventional FORTRAN, C, etc. programming languages. Using this software, students find the necessary dimensions of a machine element using design equations.

ADAMS/VRL: Automatic Dynamic Analysis of Mechanical Systems (ADAMS) is commercial software for mechanical system simulation. Students develop simple systems like Pendulum and simulates. Students also use the robots of the Virtual Robotics Laboratory (VRL) environment developed at IIT Delhi for the inverse and forward dynamics analyses.

MATLAB: Popular mathematical software for linear algebra, numerical analysis, control, and other problems. This is used to simulate dynamical model of different systems.

· RIDIM: Recursive Inverse Dynamics of Industrial Manipulators (RIDIM) is a software developed at IIT Delhi for the inverse dynamics of serial robots. This is available free of cost for education and training purposes. ridimzip.zip (3MB), install.txt (1.87KB)
