Semi-Autonomous Mobile Robot & Remote Manipulator Platform

Robotics Systems Engineering Project

System Architecture & Overview

This project involved the co-development of a mobile robotic platform designed for hybrid autonomous navigation and remote manual manipulation. The system was engineered to traverse complex environments independently and switch to a teleoperated control scheme for high-precision object manipulation.

Key Technical Contributions

Mechanical Design & Manipulation

• Manipulator Engineering: Designed the mechanical linkages and end-effector mechanisms for the robot manipulator, selecting appropriate materials and actuators to meet specific payload lifting and kinematic reach requirements.

Electrical Systems & Power Distribution

• Electrical Integration: Developed the complete electrical distribution system, implementing custom power regulation, signal isolation, and circuit protection to ensure reliable operation of all onboard logic and actuators.

Wireless Communication Protocols

• Teleoperation Links: Established robust wireless communication channels between the remote base station and the mobile robot to support bidirectional control inputs and low-latency feedback streaming.

Control Systems & Navigation Algorithms

• Motion Control: Authored control loops for precise motor actuation and implemented navigation algorithms to enable autonomous trajectory tracking and situational obstacle avoidance during the untethered mapping phase.
