The Department of Electrical and Electronic Engineering at Stellenbosch University (SU) is paving the way in humanoid robotics with the unveiling of a cutting-edge research platform. This groundbreaking platform showcases advanced robotics technology and demonstrates the power of interdisciplinary collaboration within engineering.
The humanoid robot currently stands at full height, featuring a functional torso and a fully operable right arm and hand, while its left arm is nearing completion. To enhance its human-like capabilities, the robot features a webcam for vision tracking, paired with advanced software that enables the robot to analyse and mimic human movements in real-time.
“Our system can perform inverse kinematics, enabling it to accurately follow the motions of a human operator,” says Dr William Duckitt, a lecturer in the Department. “As a result, the platform can be theoretically teleoperated from anywhere in the world, highlighting its potential for remote operation.”
Built using the EtherCAT communication protocol, the platform supports both synchronous and asynchronous processes. “This design allows us to tackle complex tasks with ease, leveraging technology I’ve used in particle accelerator control systems.”
Recognising the future potential of humanoid robotics, the Department is actively involving students in innovative projects. Several undergraduate final-year projects are underway, focusing on the design and development of custom actuators, advanced robotic hands, and humanoid arms with pincer grips, providing students with essential hands-on experience. “We aim to cultivate a new generation of researchers who will transition to master’s programs and deepen their contributions to this field,” Duckitt notes.
Looking to the future, the next stage of research will concentrate on developing actuators for the robot’s legs, with the goal of achieving bipedal walking. This advancement represents a critical step toward a fully mobile humanoid robot capable of realistic human movement and interaction.
Additionally, a master’s student is currently working on virtual robotics simulations using NVIDIA’s IsaacSim platform. This research is focused on achieving sim-to-real transfer, a technique that will initially apply simulation results to the robot arm prototype and, ultimately, help refine the functionality of the entire humanoid platform.
“Our journey in humanoid robotics combines our engineering expertise with an academic ambition to push the boundaries of what’s possible,” Duckitt reflects. “We are excited to continue sharing our progress as we advance the field of humanoid robotics.”
