The researcher hired by Toyota Motor Corp. to spearhead its robotics and artificial intelligence efforts says the automaker¡¯s production principles can be applied to build affordable helper robots for rapidly aging societies.

Robot makers are struggling with the same scale challenges that the auto industry overcame with the ¡°miracle¡± that occurred when Henry Ford developed the assembly line, according to Gill Pratt, the chief executive officer of Toyota Research Institute.

Toyota¡¯s vaunted production system later showed how to make cars both more cheaply and reliably, despite mistake-prone humans¡¯ role in manufacturing, he said.
