About

Randy Erfa Saputra is a robotics researcher whose work focuses on multi-robot coordination, autonomous navigation, and locomotion control. His research addresses fundamental challenges in how groups of robots interact and move within constrained environments. In his most cited work, "A Multi-robot System Coordination Design and Analysis on Wall Follower Robot Group" (9 citations), Saputra developed a formation control system where robots move sequentially when space is limited, with a leader robot following the right wall—a practical solution for real-world multi-robot deployment. His earlier work on mapping algorithms using ultrasonic and compass sensors (8 citations) tackled the critical problem of how autonomous mobile robots perceive and represent their surroundings. Saputra has also contributed to coordination control for simple mobile robots (4 citations), enabling formation changes when encountering obstacles, and explored quadruped robot locomotion using inverse kinematics and sine pattern methods (2 citations). His research bridges theoretical control methods with practical implementation, providing code examples and tested systems that advance the field of autonomous robotics.
