When I first watched a humanoid robot greet a child by name in a Tokyo hospital, I had a quiet realization: the future of human-robot interaction had quietly slipped out of the lab and into the hallway. That moment captures the heart of social robotics, a field I have followed closely over the past decade. … Read more
Human Robot Interaction (HRI) is the interdisciplinary field of study focused on how humans and robots communicate, collaborate, and share physical spaces. Our team has followed HRI research for years, and we have seen this area grow from a niche academic topic into a discipline shaping healthcare, manufacturing, and daily life. This guide breaks down … Read more
Robots understand spoken commands through a multi-step pipeline that turns your voice into action: microphones capture sound waves, automatic speech recognition (ASR) converts audio into text, natural language processing (NLP) figures out what you mean, and motion planning software decides what the robot should physically do. In short, a voice command is captured, transcribed, interpreted, … Read more
Whole body control in robotics is a control approach that coordinates all joints and links of a robot simultaneously to achieve task-space objectives while maintaining balance and satisfying physical constraints. Instead of telling each motor what to do one at a time, the controller thinks about the whole robot as one system working toward a … Read more
I have spent the last several months reading every humanoid robotics paper, watching dozens of fall demonstrations, and talking with engineers who have built the controllers behind today’s bipeds. The question how do humanoid robots recover from a fall sounds simple, but it sits on top of an entire stack of biomechanics, control theory, and … Read more
Most humanoid robot batteries last between 2 and 4 hours on a single charge during normal operation, but drop to 30 to 60 minutes when the robot is walking, lifting, and running AI inference at the same time. That gap between marketing claims and real workloads is the single biggest factor in whether a humanoid … Read more
When Boston Dynamics retired the hydraulic Atlas in April 2024 and unveiled an all-electric successor, the company did more than redesign a robot. They signaled the end of a 15-year debate about which actuation philosophy could carry humanoid robots from research labs into factory floors and homes. Today, electric actuators dominate every major commercial humanoid … Read more
Humanoid robot actuators are the mechanical “muscles” that convert stored energy into physical movement at every joint, allowing a robot to walk, lift, grasp, and balance. Without them, even the smartest AI is just a statue. Most modern humanoids rely on electric motors with gear reductions, but a growing share now uses series elastic designs … Read more
Most modern humanoid robots have between 28 and 56 degrees of freedom (DoF), with research platforms like Kengoro reaching as high as 174 DoF. The exact count depends on the design, but a typical full-body humanoid uses 6 DoF per leg, 7 DoF per arm, plus additional joints in the torso, neck, and hands to … Read more
When I first watched a robot hand pick up a raw egg without cracking it, I had to know what was happening under the skin. The short answer to how robot hands grip objects is this: a controller commands an actuator, the actuator moves fingers or jaws into contact with a target, and a network … Read more
