About

Hosham Wahballa is a robotics researcher whose work centers on intelligent force control for automated polishing, particularly of complex and delicate surfaces. His primary research areas include robotic contact force tracking, variable impedance control, and adaptive admittance control for manufacturing applications. Wahballa’s major contributions lie in developing novel control strategies that enable robots to maintain constant, precise contact force while polishing non-flat geometries—a critical challenge in automated finishing. His most cited work, “Constant force tracking using online stiffness and reverse damping force of variable impedance controller for robotic polishing” (2022, 34 citations), introduces a method that dynamically adjusts stiffness and damping in real time to achieve stable force control. He has also pioneered robotic polishing for cultural artifacts, as demonstrated in his 2023 study on complex violin surfaces (12 citations), which replaced labor-intensive manual polishing with an efficient, cost-effective robotic process. More recently, his 2025 paper on an Online Work-Object Stiffness PI Force impedance controller (4 citations) advances force tracking accuracy by modeling the contact dynamics as a second-order system. Wahballa’s work bridges theoretical control engineering with practical manufacturing, offering scalable solutions for industries requiring high-precision surface finishing.
