Firmware Development

• Firmware Development: 32 Bit microcontroller SoC development using FreeRTOS with sensor interfacing
• Communication: Wifi and RF based remote link with Over the Air (OTA) updates

Technologies used:

• C
• WiFi
• OTA
• RF
• RTOS

My project: JdeMultiBot was designed to extend the single robot Amazon warehouse exercise to implement a scalable, cooperative, multi-agent task and path planning system. Additionally, JdeMultiBot was intended to leverage the latest release of ROS2 (Foxy), using its features and giving students a chance to get acquainted with the new age of robotics.

Technologies used:

• C
• WiFi
• OTA
• RF
• RTOS

Cloud and Predictive Maintenance agent development

• Machine Learning Agent: ML agent which processes, trains, predicts and visualizes data. A number of different algorithms and data inputs are supported. In addition, RESTful application interface is made available to use.
• Chariot Cloud: Created REST API service which handles big data operations in MongoDB and MySQL. The data API is generic and reusable across different use cases.
• Maintenance Agent: Java (JIAC) agent which handles machine learning training and prediction requests.
• CHARIOT platform connects various decentralized devices in an Industry 4.0 factory environment such as Conveyor Belt and image Sensor with service components such as monitoring, maintenance and task scheduling. The communication protocol is open source, JAVA based JIAC framework and REST API.

Technologies used:

• Python
• Java
• MongoDB
• MySQL
• JIAC Agent
• RESTful Services
• Machine Learning
