The Arrival of Robot Autonomy
Episode 1 of Robotics Series
Plunge into the world of robots with this engaging introduction. When did we start thinking about robots? What three components are responsible for so many advances in robot design? Why is behavioral autonomy so essential to the development of modern…
Self-Driving Vehicles
Episode 14 of Robotics Series
Lane changes, off-roading, irregular traffic patterns--how do robotic cars handle it all? Find out in this lecture on the trade-offs (especially between speed and safety) involved in creating self-driving vehicles. Peer into the future of how you're likely to get…
The Futures of Robotics
Episode 24 of Robotics Series
Because it's a multidisciplinary field, there isn't just one future for robotics, but instead multiple futures. What could some of them look like? Consider everything from companion robots that can coordinate our activities to surgical robots that can work autonomously…
Basic Skills for Making Robots
Episode 8 of Robotics Series
So you want to make a robot. Where should you start? Learn how to work with tools like multimeters and solid-core wires; how to perform basic tasks including stripping wire and building simple circuits; and how to "hack" into existing…
Robot Bodies and Trade-Offs
Episode 2 of Robotics Series
Why just watch robots when you can understand how they actually work? Deconstruct a Roomba to learn the five functional categories of parts all robots need. Then, explore a universal lesson about robotics: because robots can't do everything well, trade-offs…
Robot Actuators and Movement
Episode 3 of Robotics Series
Investigate robot actuators: the motors and transmissions that underlie all robotic movement. You'll learn about the early use of springs as motors in automata; how electricity spins the magnets that make motors move; how movement defines what a robot is;…
Robot Controllers and Programming
Episode 5 of Robotics Series
What turns a remotely controlled machine into an autonomous robot? Self-control. So where does self-control in robots come from? Find out in this lecture on robot controllers: the computer-like part of robots that uses sensory information to decide how the…
Social Robots
Episode 22 of Robotics Series
Enter the brave new world of social robotics, where robots are built specifically to communicate with humans and other autonomous physical agents. With the help of the robot Baxter, discover how simple signals like spoken words, expressions, and body language…
Swarm Robots
Episode 20 of Robotics Series
A huge challenge in robotics is getting robots to work as a team to do things they can't do alone. Enter swarm robots: simple, similar mobile robots that combine to generate complex behaviors. Investigate this area of robotics that's barely…
Humanoid Robots: Just like Us?
Episode 23 of Robotics Series
Have we reached the point where robots are becoming just like--if not better than--human beings? Probe this fascinating question by examining recent developments in artificial intelligence, robot bipedalism and dexterity, the concept of the "uncanny valley," and three imitation games…
Living Robots?
Episode 21 of Robotics Series
Robots are starting to perform the core features of life, to the point where it may be possible to have a robot that actually "lives." Professor Long introduces you to robots that "eat" by harvesting energy; robots that "grow" by…
Flying Robots: From Autopilots to Drones
Episode 15 of Robotics Series
Take to the air for an eye-opening look at aerial robots, from the autopilot features in commercial airplanes to unmanned drones that can deliver packages. Topics include the role of gyroscopic sensors and recent technological advancements that are extending the…
Mobile Robots at Home
Episode 12 of Robotics Series
Advancements in modern robotics have made robots useful, safe, reliable, easy to use, and affordable to have in our homes. So how exactly do different home robots--such as vacuum cleaners like Roomba, gutter cleaners like Looj, and lawn mowers like…
Animal-Inspired Robot Behavior
Episode 7 of Robotics Series
Consider an approach to creating robots that's inspired not by maps but by the simple sense-and-act behavior of animals. You'll learn the benefits of behavior-based robotic architecture (including quicker reactions and stronger sensors), and see how simple animals including ants…
Space Robots in Orbit and on Other Worlds
Episode 17 of Robotics Series
Find out how space missions have pushed us to the limits of what autonomous robots can do. Central to this lecture are several fascinating robots, including Robonaut 2 (a humanoid robot working on the International Space Station) and the rovers…
Why Military Robots Are Different
Episode 18 of Robotics Series
Explore the tension between semi-autonomous military robots and our need to oversee their safety and control. In looking at military robots such as the Predator unmanned aerial system and the Phalanx weapons system, you'll learn about the unique trade-offs involved…
Robot Arms in the Factory
Episode 11 of Robotics Series
Each year, many tens of thousands of new robots are purchased to help us manufacture cars, medicines, and other everyday materials. And it all started with variations on the robotic arm. Here, examine early prototypes of pick-and-place robots; consider the…
Robot Sensors and Simple Communication
Episode 4 of Robotics Series
Intelligent behavior in robots is rooted in the sensors that determine how much robots know about the world around them. Professor Long demonstrates how sensors work to communicate across the electromagnetic spectrum, including through infrared (like in Roombas) and visible…
Designing a New Robot
Episode 9 of Robotics Series
Move from kits and hacks into the actual design and construction of more complex robots for research or business. As you explore the iterative decision-making process used by robotics engineers, you'll meet intriguing robots including Madeline, the first transphibian vehicle,…
A Robot for Every Task?
Episode 10 of Robotics Series
Wouldn't it be great to have a robot that took out your trash or put away your books? Explore how robots are designed to perform specific tasks, and the choices roboticists must consider in doing so--including the stability of the…
