Caltech engineers are making waves with a new multimodal robot system. This unique creation combines a humanoid robot with a drone that launches from its back. The humanoid, a Unitree G1, is equipped with a drone called the M4. This isn’t your typical sci-fi robot; instead, it shares some traits with transformer toys, as the drone can switch between flying and driving modes.
This project comes from a partnership between Caltech’s Center for Autonomous Systems and Technologies (CAST) and the Technology Innovation Institute (TII) in Abu Dhabi, UAE. The development took three years, showing the depth of collaboration and innovation.
The humanoid robot can walk, climb stairs, and navigate to wherever it sends the drone, though it does so at a slow pace. “Right now, robots can fly, drive, and walk,” noted Aaron Ames, the director of CAST. “But how do we integrate these movements into a single system that benefits from each?”
The challenge was to combine different types of robots into one efficient system. The drone was crafted by a dedicated team, while Ames and his lab configured the humanoid. M4 can adjust its body and movements based on the environment it encounters. It can roll on wheels, take flight with propellers, and even navigate steep slopes.
M4’s design allows it to repurpose its parts creatively. For example, when it needs to fly, its wheels lift away, letting the propellers take over. This versatility is crucial in making robots more reliable and adaptable in various situations.
Ames emphasizes the importance of safety in autonomous systems. As we rely more on robots, ensuring their reliability becomes paramount. “We’re focused on secure control,” he said. “Our projects tackle various challenges in autonomy to make significant progress.” This commitment to safety and innovation is essential as we move forward in an increasingly automated world.
Interestingly, recent surveys show that public opinion is shifting favorably towards robots. A 2023 survey revealed that 70% of respondents feel comfortable with increased automation in daily tasks. This signals a growing acceptance of robotic technology, which is essential for innovations like Caltech’s multimodal robot system.
As these technologies continue to develop, we might see this kind of robot integrated into everyday life — from delivery drones to search-and-rescue missions. With ongoing research and advancements, the future of robotics looks bright.
