Jul 2017-Dec 2021 ABB INC. San Jose, CA, USA

Jul 2017 – Sep 2019 Colider V1

Descriptions: 3D vision system for general purpose Vision Guided Robotics (VGR) application development for ABB Robotics. Images captured using the 3D camera are processed by the vision algorithms using OpenCV, and PCL libraries, and the output is sent to the VGR application to manipulate the Robot.

Software and Hardware Requirements for this project include Vision system Nvidia Jetson Tx2- aarch64, Intel RealSense, FRAMOS, SICK cameras, GNU/Linux Ubuntu, JetPack, CUDA, Cmake, OpenSSL, C/C++, Python, Node.js, MongoDB, MongoDB-C, GridFS, REDIS, hiredis, RabbitMQ, AMQP-CPP, Nginx, PCL, OpenCV, VTK, JSON,

My Contributions:

• I developed modules with various API interfaces to covert the captured images from one format to another format like Mesh to Mesh (STL, VTK, obj, ply) File saving, Mesh (STL, VTK, obj, ply) to PCD File saving or boost pcl::PointCloud pointer, PCD to Mesh (STL, VTK, obj, ply) File saving or boost pcl::PolygonMesh pointer.

• I developed modules with various API interfaces for Image Registration and ROI calculation for various regular geometric shapes or irregular shapes.

• I developed modules with various API interfaces to store and retrieve various types of objects to and from the Redis database and MongoDB.

• I developed a module to provide an environment within the vision software to execute a Python script and returning the results back to the vision software using the OLE (Object Linking and Embedding) technique.

• I developed modules with various API interfaces to monitor the configured computer resources (CPU, RAM, DISK, NETWORK, TEMPERATURE, and POWER) to check whether it is out of the configured limit level. If any of the resources are out of the configured limit, an alarm message will be sent to the GUI. Each resource could be monitored in its individual configured time interval. The time interval for each resource could be set in the option filed in MongoDB. Each resource could be individually turned on or off for monitoring its usage limit.

• I developed modules for vision system administrations like backup, restore, patching, software install, update, start, stop, restart component services, alarms, and audit logs. Skills and Expertise I used: Linux Ubuntu, C/C++/C++ 11, Python, CMake, MongoDB, MongoDB-C, GridFS, PCL, OpenCV, VTK, JSON,

Oct 2019 – Dec 2019 New Concept and Methodologies proposals for new project development Descriptions: I proposed the following new concepts, methodologies, and system architecture for implementing the Colider-V2. I also developed a working proof-of-concept and demonstrated it.

• Collaborative Services-Oriented Architecture: In this architecture, the Components collaboratively implement an application solution, Each Component offers and/or consumes a specific service, Components should respond within a specified time limit, and Components should operate within a restricted resource limit. A software component is a unit of composition with contractually specified interfaces and meets characteristics of Reusable, Compose-able, Independent, Encapsulated, Enhanceable, Time and resource constraints, and Comprehensive/Complete.

• Implementation of abstraction layer in software system development: In software, abstraction is the process of generalization by implementing the “is-a” relationship between objects by grouping different similar objects and generalizing its functionalities as an interface for the use of the outside world. By implementing the abstraction layer the common functionalities of different objects are implemented only once, code re-usability is enforced, and implementation is separated from the interface, making the interface independent of any changes that occurs in the implementation.

My Contributions: I designed, developed proof-of-concept, and demonstrated. Skills and Expertise I used: My software design and system architecture knowledge. Linux Ubuntu, C/C++/C++ 11, CMake, JSON.
