Introduction to robotics

Also listed as: מבוא לרובוטיקה

Kinematics, the Jacobian, trajectories and dynamics. It is also the mandatory gate to the robotics lab, so it has to be taken in the fall before the lab you want in the spring.

Comes after

  • Rigid body dynamics
  • Linear algebra

What it covers

Kinematics

  • Rigid-body motion, rotations, homogeneous transforms
  • Forward kinematics by the Denavit–Hartenberg convention
  • Inverse kinematics: geometric and algebraic, kinematic decoupling, the spherical wrist
  • Velocity kinematics and the Jacobian, singularities, manipulability, pseudoinverse
  • Statics and force transmission

Motion and control

  • Trajectory generation: joint-space polynomials, trapezoidal profiles
  • Dynamics by Euler–Lagrange and Newton–Euler
  • Introduction to control: PD and computed torque
  • Introduction to mobile robots, sensing and vision

Results worth carrying out

  • Forward kinematics

    Tn0=A1A2AnT_n^0 = A_1 A_2 \cdots A_n
  • Velocity kinematics

    v=J(q)q˙v = J(q)\,\dot{q}
  • Manipulator dynamics

    τ=M(q)q¨+C(q,q˙)q˙+g(q)\tau = M(q)\ddot{q} + C(q,\dot{q})\dot{q} + g(q)

Figures worth knowing

  • Denavit–Hartenberg frame assignments
  • Workspace plots
  • Jacobian singularity sketches
  • Trajectory profiles

We also write the summaries.

This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
