About this PDF

The Beginner book opened the moving machine. Advanced study connects geometry, rates, effort, observations and decisions - powerful only while their assumptions stay visible, because a matrix product can be correct while a conclusion about the physical world remains unsupported. All explanations are in Bengali. This 55-page guide runs through 20 original units on paper: why a model needs an evidence boundary; rotation as more than four numbers; composing frames in a named order; undoing the rotation as well as the offset; forward kinematics as a declared map; inverse choices with explicit limits; a Jacobian as instantaneous change; why a singularity depends on the stated task; the transpose mapping effort through the same geometry; wheel odometry accumulating a model; fitting a response and inspecting what remains; weighted agreement under a chosen objective; time alignment as part of the model; a numerical step's own approximation; feedback stability as a statement about a recurrence; how one delayed value changes the equation; a path needing a clock to become a trajectory; A-star's justified optimistic estimate; clear endpoints that can hide contact between them; and a capstone building an inspectable model review. Every unit has a lesson and a workshop with a worked case, safe activity and explained answers. Every workshop uses invented records on paper, with optional harmless offline arithmetic - no robot, powered equipment, programming installation or live network is needed. Exact angles are sometimes named in degrees; trigonometric derivatives and wheel-angle formulas use radians. Best suited to readers comfortable with algebra, matrix multiplication, elementary trigonometry and basic differentiation who want the mathematics behind robot motion with its limits kept in view. Every dimension, observation, limit and gain is invented for learning; every method is shown on an invented case first. Important: this is education, not equipment operation training, s
