Mobile ALOHA: A Low-Cost Holistic Teleoperation System for Data Collection

The researchers at Stanford University have developed a low-cost, comprehensive teleoperation system called Mobile ALOHA for gathering data on comprehensive teleoperation. By placing it on a wheeled base, Mobile ALOHA extends the capabilities of the original ALOHA and gains mobility. The researchers used the static ALOHA dataset for imitation learning and achieved good performance in mobile manipulation tasks. This system offers a low-cost and efficient method for data collection, suitable for tasks that require comprehensive teleoperation in everyday scenarios.

Want to Make Robots Smarter? Tsinghua Team Discovers the Secret to Accelerated Robot Learning

The rapid development of deep learning relies on the scale of datasets, models, and computational power. In the fields of natural language processing and computer vision, researchers have already discovered a power-law relationship between model performance and data scale. However, in the field of robotics, especially in robot manipulation, such scalable patterns have yet to be established. A research team from Tsinghua University recently published a paper exploring data scaling laws in robot imitation learning and proposed an efficient data collection strategy that collected sufficient data in just one afternoon, enabling...

MIT Unveils New Robot Training Model to Tackle Problems in a Simpler, More Direct Way

The Massachusetts Institute of Technology (MIT) showcased a brand new robot training model this week that abandons the previous focus on training methods centered around specific datasets, opting instead for an approach that utilizes vast amounts of information similar to that used in training large language models (LLMs). Researchers noted that imitation learning—where agents learn by mimicking individuals performing tasks—can fail when facing minor challenges. These challenges may include varying lighting conditions, different environmental setups, or new obstacles. In such cases, the robots lack sufficient data to adapt to these changes.

MIT Unveils a Method Inspired by Large Language Models to Teach Robots New Skills for the First Time

This week, MIT showcased a new model for training robots, aimed at addressing the challenges faced by imitation learning when introduced to small obstacles. Researchers pointed out that imitation learning can fail in conditions such as varying lighting, different environments, or new obstacles because robots simply do not have enough data to adapt. The team sought powerful data methods, like those used in models such as GPT-4, to tackle the problem. They introduced a new architecture called the Heterogeneous Pretrained Transformer (HPT), which aggregates information from different sensors and environments.
