Courses

The following courses are offered at the Robert Bosch Centre for Cyber Physical Systems for August-December 2020 semester.

CP 312 : Foundations of Robotics

Instructor : Prof. Shishir N. Y. Kolathaya

Background: This graduate course will serve as an introductory robotics course for students with little/no background in mechanical systems. The course will first build the necessary mathematical framework in which to understand topics such as center of gravity and moment of inertia, friction, statics of rigid bodies, principle of virtual work, kinematics of particles and rigid bodies, impacts, Newtonian and Lagrangian mechanics, rigid body transformations, forward and inverse kinematics, forward and inverse dynamics, state space representations. Towards the end of the course advanced topics such as rigid body collisions, and hybrid dynamical systems will also be covered.

Prerequisites: Students must be well versed with basic mathematical concepts like linear algebra and classical analysis. Suggested courses are MA 219 and MA 221.

Credit Hours: This will be a 3:1 credit course.

Syllabus: Kinematics of particles and rigid bodies, statics and dynamics of rigid bodies, moment of inertia, principal of virtual work, conservation of energy and momentum, collisions, configuration space, task space, rotation groups, rigid transformations, forward and inverse kinematics, forward and inverse dynamics, holonomic and nonholonomic constraints, hybrid systems, hybrid modeling.

CP 212 : Design of Cyber-Physical Systems

Instructors: Dr. Ashish Joglekar / Darshak Vasavada

Background: This is an interdisciplinary course on the design of cyber-physical systems, inviting students from all the departments. It provides an in-depth exposure to various elements of a CPS: the microprocessor, interfacing physical devices (analog and digital) and control systems basics.

Prerequisites: Students must be familiar with any microprocessor and analog/digital circuits, C programming.

Credit Hours: This will be a 2:1 credit course.

Syllabus: 

  1. Microprocessor system –
  • Computer organization: memory, IO ports, clock and power management. Flash & security.
  • Microprocessor architecture: overview of Cortex A, R and M series. Cortex v7m architecture.
  • Software architecture: OSless systems, startup code, main code.

  2. Interfacing physical devices –

  • Structure of a device driver
  • Write device drivers: GPIO and timers
  • Use device driver APIs: GPIO, timers, UART, ADC

  3. Control system basics –  We will cover basics of on-off (hysteretic) and PID control, analysis of system stability and tuning of feedback parameters.

  4. EMI/EMC considerations – Design for EM compliance is important for a product to work without failure in its intended EM environment. We will cover the EMI Noise Path Model, Modes of coupling and EMI/EMC regulations with experiments on EM susceptibility and mitigation.

  5.  Network connectivity – We will cover wireless communication protocols and visualize the sensor data via a cloud based middleware.
