calculations to downselect a few better candidates, propose modification to these
solutions if required, preliminary modeling, set-up design/algorithm development,
fabrication/code development, experiments/benchmarking, analysis and interpretation of
the results. The project must deliver a hardware or a computation package along with the
detailed report summarizing the same.

(Design,
Manufacturing,Thermal and Fluids) streams of the mechanical engineering
3. The pool of projects with well-defined practical problems should be announced at

ME 512 Mobile Robotics (3-0-0-6)
Objectives: Mobile robots are now enabling human beings to physically reach and explore
unchartered territories in the Universe. Be a place as distant as Mars, in abysmal depths
of ocean, or shrouded by thick glaciers of Antarctic, mobile robots help exploring
everything; yet this is just the beginning. Even in day to day life autonomous cars hold a
potential to revolutionize transportation and domestic mobile robots help humans in
cleaning, elderly help, etc. National defense is an area replete with the use of mobile
robots. This course will present various aspects of design, fabrication, motion planning,
and control of intelligent mobile robotic systems. The focus of the course is distributed
equally on the computational aspects and practical implementation issues and thereby
leads to a well rounded training. The course will give students an opportunity to design
and fabricate a mobile robotic platform and program it to apply learned theoretical
concepts in practice as a semester long class project.
Syllabus:
Robot locomotion: Types of locomotion, hopping robots, legged robots, wheeled robots,
stability, maneuverability, controllability;
Mobile robot kinematics and dynamics: Forward and inverse kinematics, holonomic and
nonholonomic constraints, kinematic models of simple car and legged robots, dynamics
simulation of mobile robots. Perception: Proprioceptive/Exteroceptive and
passive/active sensors, performance measures of sensors, sensors for mobile robots like
global positioning system (GPS), Doppler effect-based sensors, vision based sensors,
uncertainty in sensing, filtering; Localization: Odometric position estimation, belief
representation, probabilistic mapping, Markov localization, Bayesian localization, Kalman
localization, positioning beacon systems. Introduction to planning and navigation: path
planning algorithms based on A-star, Dijkstra, Voronoi diagrams, probabilistic roadmaps
(PRM), rapidly exploring random trees (RRT), Markov
Decision Processes (MDP), stochastic dynamic programming (SDP);
Robotics Project: Students will work on a semester long project consisting of design,
fabrication, and programming a mobile robotic platform.
