AI Mentor for Robotics & Artificial Intelligence Students
Every algorithm you debug today is one less robot arm crashing into a wall tomorrow.
An engineering student asks Sumantrak
“explain forward and inverse kinematics for a robotic arm for viva”
Forward kinematics: given the joint angles, compute the end-effector's position and orientation — a straightforward calculation by chaining each link's transformation matrix (DH parameters), one function composition. Inverse kinematics: given a desired end-effector position, find the joint angles that get there — much harder, since the equations are nonlinear and a single target position can have zero, one, or many valid joint-angle solutions depending on the arm's reachable workspace. Viva tip: examiners often ask why inverse is harder than forward — say plainly: forward is just plugging numbers into a known chain of equations, inverse means solving that chain backwards, which isn't always unique or even solvable.
