The robot uses LG’s EXAONE vision-language AI, which gives it the ability to interpret objects, spaces and human instructions. As a result, it can adapt to new situations without heavy reprogramming. Its tactile hands also help it perform delicate tasks with more control than many early-generation humanoids.
LG and KIST designed KAPEX for practical work, not just lab research. They aim to test it in factories, logistics centers and public environments. Moreover, the team wants it to learn from each task, gradually improving its skills over time.
