It's being worked on, but not nearly to the same extent as machine perception. And yet it's probably the biggest technology gap preventing us from deploying human-equivalent robots in unstructured environments.
From seeing the robotics field from a distance - the issue doesn't simply stop at high-level intelligent algorithms; there is also the problem with actual hardware. The human body is an incredibly efficient biomechanical system that can perform a wide array of delicate movements, and current robotic systems are still too far away from reasonably mimicking human muscles, joints, and sensory nervous systems. Robots might still has difficulty in performing everyday tasks done by humans, even if the algorithms are intelligent enough.
