MIT researchers develop new approach for training general purpose robots

MIT develops new method for robot training using HPT inspired by GPT-4.

: MIT researchers introduced the Heterogeneous Pretrained Transformers (HPT) for training general-purpose robots, drawing inspiration from large language models like GPT-4. This approach allows robots to learn various tasks by integrating diverse datasets, such as human demonstrations and simulations. HPT, outperforming traditional methods by more than 20%, utilizes a massive dataset with 52 datasets covering over 200,000 robot trajectories. The initiative is partly funded by Amazon and the Toyota Research Institute.

MIT researchers have developed the Heterogeneous Pretrained Transformers (HPT) approach, inspired by the success of models like GPT-4, to advance the training of general-purpose robots. This method combines diverse data, such as human demonstration videos and simulations, into a singular system, allowing robots to adapt to a wide array of tasks.

The use of a large dataset of 52 datasets, incorporating over 200,000 robot trajectories, allows for effective knowledge transfer and reduces the need for fine-tuning with specific data. HPT has demonstrated superior performance compared to traditional training approaches, achieving more than a 20% improvement even in tasks that significantly differ from the pretraining data.

The project received funding from the Amazon Greater Boston Tech Initiative and the Toyota Research Institute. MIT's team envisions a future where a universal 'robot brain' can be applied to various robots without specialized training, similar to developments in large language models.
