Toyota Research Institute experiments with robots that hang from the ceiling and unfold to clean the kitchen

Researchers are using fleet learning and simulations to train robots to navigate one of the most complex environments: A home.

Working in a factory is easy for robots with the structured environment and repetitive tasks that come with that job. Helping with housework is a much bigger challenge. Scientists at the Toyota Research Institute (TRI) are taking on that challenge by building new domestic robots and training them in a mock home.

Gill Pratt, the CEO of TRI and Kelly Kay, the Institute’s executive vice president and chief finance officer, gave a virtual tour of the TRI labs on Thursday. Max Bajracharya, the vice president of robotics and Steffi Paepcke, the senior user experience leader, explained the research and development process for building these robots. 

The team is prioritizing user experience research, human-centered design, and ikigai–the idea that each person’s life should have deep meaning and purpose. 

The institute’s philosophy is to build robots that take over tasks that have become too difficult for older adults instead of building a one-size-fits-all robot to take over all activities. One prototype is a gantry robot that unfolds from the ceiling to help with household tasks like a bat unfolding its wings. 

The floor model looks like a praying mantis perched on a box. Researchers are using these models to develop capabilities. 

“The robots that you see today are prototypes to accelerate our research, but they are not going to be turned into products any time soon,” Bajracharya said.

Paepcke said the team used the “genchi genbutsu” research technique which means, “go see for yourself,” to understand how to build domestic
