Cyber-Physical Systems and Tactile Internet

Designing Tactile Cyber-Physical Systems (TCPS)

  • Designed and executed a Tactile Cyber-Physical System (TCPS) connecting a haptic device and a robotic arm for live teleoperation.
  • Developed pose correction algorithm that automatically adjusts the pose of a robot while gripping a tool.
  • Developed tremor suppression algorithm that suppresses tremors in the robot arm while controlling it using a haptic device.

Time Sensitive Networking (TSN) switch

Built IEEE 802.1 TSN-capable ethernet switches using SmartNICs hardware implementation of time synchronization (IEEE 802.1AS), Time Aware Shaper (IEEE 802.1Qbv), and packet duplication/elimination (IEEE 802.1CB).

Novelties:
  • Β΅TAS - Designed a P4-MicroC-based SmartNIC that offloaded Time-Aware Shaper and achieved 20Β΅s latency between hosts across two switches.
  • Implemented packet de-duplication algorithms that ensured 100% and 99.83% packet delivery for two and tweleve streams respectively across two links each with 10% loss.
  • EdgeP4 - Embedding intelligence for pose correction and tremor suppression in P4-programmable edge switches, reducing control loop latency (<100Β΅s) and network load (99% reduction) and demonstrating versatility in algorithm-switching for distinct tasks via P4's match-actions.

Yaw control of a CubeSat using reaction wheels

  • Designed a suspended CubeSat body and achieved precise control of its yaw using reaction wheels using a manually tuned PID controller.
  • Modeled it in Simulink and implemented Model Reference Adaptive Control (MRAC) using the MIT rule and achieved better performance compared to PID control.

IoT data management, indoor localization and security

Acoustics Based Localization

  • Developed an application to locate multiple wireless edge devices with embedded microphones by using audio signals from speakers.
  • Simulated a few localization algorithms using MATLAB. Implemented KNN fingerprinting based localization of the receivers and achieved an accuracy of 98%.
  • Novelty - Unlike the usual source localization, here, the receivers (mics) are localized when the locations of speakers are known.

Airplane IoT data analytics and management

  • Developed machine learning algorithms to classify anomalies and take corrective actions using real-time data generated from sensors from a MATLAB/Simulink model of an aircraft environmental control system.
  • Novelty - Developed an algorithm that does linear interpolation between non-consecutive data points from time series data to adaptively store data based on a cost function which balances storage space savings and error in reconstruction of data. Achieved 96% savings in storage space.

Video casting

  • As 2.4 & 5 GHz Wi-Fi is congested in an aircraft cabin in which 400+ passengers cast media onto seat back displays in close proximity, using IEEE 802.11ad, 60GHz Wi-Fi (Wi-Gig) & 802.11ax (Wi-Fi 6E) was explored.
  • MATLAB WLAN Toolbox was used to simulate the physical behavior of Wi-Fi transmissions in a dense environment.
  • Novelty - Developed an algorithm that dynamically allocates different channels to 400 transmitters such that the packet error ratio is zero (PER = 0).
