The Construct - Robotics Developer Masterclass Program

RB1 Robot Warehouse Navigation Project

Developed a Python script utilizing the Simple Commander API to orchestrate navigation tasks for the RB1 mobile robot, including localization, shelf manipulation, and waypoint navigation.
Implemented a Costmap Filter to generate a Keepout Mask, employing navigation algorithms and path planning techniques to enhance the robot’s safe navigation in complex environments by avoiding predefined obstacle areas.
Integrated the Costmap Filter into the navigation stack by configuring navigation launch files, planner settings, and controller parameters.

UR3e Pick and Place Project Using Perception

Developed a Perception node using ROS2 to detect the position of a cube on a table using point cloud data from the UR3e robot's wrist camera.
Created a C++ client program to communicate with the Perception action server and retrieve object coordinates, enabling the robot to autonomously pick and place objects based on real-time perception data.

Web Development Project for Robotics

Developed a web application to control the TortoiseBot robot, leveraging HTML, CSS, JavaScript (Vue.js), and ROSLIB for web development and ROS integration.
Integrated features including map visualization, 3D robot model display, live camera feed, virtual joystick for manual control, and waypoint buttons for navigation.
Designed an intuitive and user-friendly interface for robot control and provided real-time visualisation of mapping progress, robot model, and camera feed.

Docker Project for Robotics

Developed Docker images for deploying the TortoiseBot robot in both ROS1 and ROS2 environments, ensuring consistent and reproducible environments across different platforms, and enhancing development and deployment workflows.
Created separate images for simulation and real robot setups, including components for Gazebo simulation, mapping, waypoints, web application, camera, and laser.
Utilized Docker and Docker Compose for containerization and orchestration of robot applications, simplifying the setup and deployment process and facilitating use by new users.

Trash Table Detection Using Lidar Sensor

Developed a trash table detection system using 2D Lidar segmentation algorithms, successfully deploying a real-world application on the Cleaner robot to autonomously detect, approach, and pick up trash tables.
Developed ROS2 nodes to control the Cleaner robot's approach to the trash table and its elevator mechanism, implementing Nav2 for autonomous navigation.

SAE International – Robotics for Autonomous Vehicle Systems Bootcamp

Pure Pursuit (Carrot Planner) Implementation

Recorded waypoints using waypoint_logger.py and manual driving, developing and implementing the pure pursuit algorithm in pure pursuit.py for waypoint following.
Parsed the waypoint .csv file and implemented logic for 'instantaneous carrot position.' Tested and adjusted lookahead_distance for accurate interpolation, culminating in the implementation of pure pursuit control code for the car to follow waypoints. Capstone Project on Real TurtleBot3 Burger Robot.
Achieved fully autonomous navigation of Turtlebot3 Burger in a structured environment, leveraging skills in ROS development, SLAM, object detection and tracking, navigation algorithms, python programming, and OpenCV for image processing.
Integrated wall following, line following, go-to-goal navigation, obstacle avoidance using laser scans and object detection, and autonomous navigation task switching based on predefined triggers or positions.
