Google DeepMind has unveiled two impressive AI systems, ALOHA Unleashed and DemoStart, that are revolutionising robot dexterity and manipulation capabilities. These advancements represent a significant leap forward in enabling robots to perform complex, human-like tasks with precision.
ALOHA Unleashed, the latest iteration of the ALOHA (A Low-cost Open-source Hardware system for bimanual manipulation) platform, has demonstrated remarkable abilities in two-armed manipulation tasks. Key achievements of ALOHA Unleashed include:
- Tying shoelaces
- Hanging shirts
- Repairing other robots
- Inserting gears
- Cleaning kitchens
The system builds upon previous versions, incorporating teleoperation for more efficient training and data collection. This approach allows robots to learn new tasks with fewer demonstrations, significantly enhancing their adaptability and potential applications.
In parallel, DeepMind has introduced DemoStart, an innovative reinforcement learning algorithm designed to bridge the gap between simulated learning and real-world performance. DemoStart has shown impressive results, particularly when applied to multi-fingered robotic hands. Its key achievements include:
- Requiring 100 times fewer simulated demonstrations to master tasks compared to traditional methods
- Achieving a 98% success rate on various simulated tasks
- Demonstrating a 97% success rate on real-world cube reorientation and lifting tasks
- Successfully performed a plug-socket insertion task with 64% accuracy, showcasing high-finger coordination and precision.
These advancements bring us closer to a future where robots can assist humans in a wide range of tasks, both at home and in the workplace. The ALOHA system, in particular, has shown potential for applications such as cooking and doing laundry through teleoperations and imitation learning.
