Reaching Out a Hand from Afar: Teleoperation
Teleoperation lets a person control a distant machine directly, sending their hands and eyes where people cannot safely go. This article covers its origins in 1940s–50s nuclear lab

Machines That Move With Soft Bodies: Soft Robotics
Soft robotics builds robots from flexible materials such as rubber and silicone, taking inspiration from creatures like the octopus and the elephant's trunk. This article covers ho

The Robot That Walks Without Trying: Passive Dynamic Walking
Passive dynamic walking is the idea that a machine can walk using only gravity and inertia, with no motors or controllers, as long as its body shape and weight distribution are rig

Three Promises Robots Must Keep: Asimov’s Three Laws of Robotics
Asimov’s Three Laws of Robotics are a set of prioritized rules: a robot must not harm humans, must obey human orders, and must protect itself. We look at how the laws were born, wh

Working Side by Side with People: Collaborative Robots (Cobots)
A collaborative robot, or cobot, is a robot designed to share a workspace with people and to reduce its own force and speed when it comes close or makes contact, so no one gets hur

Smarter Together Than Alone: Swarm Robotics
Swarm robotics is the field of robotics that designs many simple robots to work together without a central leader, using only signals exchanged with nearby peers. This piece covers
Robotics
From Fingertip Goals Back to Joint Angles: Inverse Kinematics
Inverse kinematics finds the joint angles that place a robot’s end effector at a desired pose. This piece covers forward versus inverse kinematics, multiple or missing solutions an

The Secret to Walking Without Falling: The Zero Moment Point
The Zero Moment Point (ZMP) is the point under the feet where ground forces create no tipping moment, long used to judge whether a biped robot will fall. This piece covers the supp

Drawing the Unknown on Its Own: Simultaneous Localization and Mapping (SLAM)
How does a robot with no map work out both its surroundings and its own position? This piece explains SLAM: the chicken-and-egg problem behind it, its roots in the 1986 IEEE roboti

The Easy Things Are the Hardest: Moravec's Paradox
Why can computers beat chess champions yet struggle to pick up a cup? This article covers the origins of Moravec's paradox, its evolutionary explanation, examples from robotics, an

Reducing Error on the Way to the Goal: Proportional-Integral-Derivative Control
How do robot arms and drones stop right at their target? This article covers the history of PID control starting with Minorsky, the roles of the proportional, integral and derivati

The Number of Joints Shapes Movement: Degrees of Freedom
What determines how a robot can move? This article explains degrees of freedom, covering what the term means, how six-axis industrial robot arms work, the degrees of freedom of the
