# Wheeled Biped Robots Roadrunner by RAI Institute Combines Wheels and Legs for Hybrid Movement By Amy Duong | Published 2026-03-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/roadrunner-1 References: [rai-inst](https://rai-inst.com/)  The Roadrunner robot by the RAI Institute is a bipedal-wheeled prototype designed for multi-mode locomotion. Weighing around 15 kilograms, the robot replaces traditional feet with wheels, allowing it to roll efficiently on flat surfaces while still using articulated legs to step over obstacles. Its symmetrical leg design enables the knees to rotate forward or backward, adapting posture depending on terrain. Movement is controlled through a single AI policy trained in simulation, allowing the robot to switch between driving, skating, and stepping without separate systems. This unified control enables behaviors such as balancing on one wheel, standing up from different positions, and transitioning between modes without additional calibration. The system is designed to reduce the gap between simulation and real-world deployment, allowing the robot to operate immediately after training without manual adjustment.
