Boston Dynamics' 2010 demo of BigDog, a quadruped robot that climbs through woods, recovers from kicks, slips on ice and jogs at 5 mph. It was an early showcase of dynamic legged locomotion.

Lex Fridman's two-hour podcast with George Hotz, founder of Comma.ai, covering openpilot, autonomous driving and Hotz's views on AI and technology.

Aging Wheels tests how towing trailers affects the range of electric trucks, including a Silverado EV. It shows that trailer aerodynamics matters far more than added weight.

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.

Fully Charged episode where Elliot drives the NIO ES8 SUV and visits a battery swap station that replaces the pack in about three minutes. It covers the ownership model of swapping and what it could mean for EV charging.

A short clip from Swedish magazine Teknikens Värld showing the 2016 Toyota Hilux nearly tipping over during the evasive-maneuver moose test.

Boston Dynamics shows its Atlas humanoid robots running a parkour course with jumps, balance beams and vaults, demonstrating whole-body athletic control.

A short Boston Dynamics clip of the Sand Flea, an 11-pound RC-car-style robot that can jump about 30 feet into the air. An onboard stabilization system keeps it oriented in flight and for landings.

A short Boston Dynamics clip of the Atlas humanoid robot doing parkour, jumping over a log and leaping up steps using whole-body control and computer vision to locate markers.

A short Boston Dynamics demo of Handle, a wheeled mobile manipulation robot that builds and unloads mixed-box pallets in a warehouse. It uses vision to find boxes and force control to place them against neighbors.

Boston Dynamics shows the electric Atlas autonomously moving engine covers between containers and a sequencing dolly. It uses an ML vision model and grasping policy with no teleoperation or prescribed motions.

A short Boston Dynamics demo of RHex, a 30-lb six-legged robot built for rough terrain, remotely operated with a video uplink and about four hours of battery life. It can run right-side-up or upside-down.

Boston Dynamics shows its Atlas humanoid robot performing a gymnastics and parkour routine, using optimization-generated motions and a model predictive controller.

A short Boston Dynamics clip of the DARPA-funded Cheetah quadruped robot hitting 28.3 mph on a treadmill, slightly faster than Usain Bolt's fastest 20 meter split.

Boston Dynamics' New Year video shows its Atlas, Spot and Handle robots dancing to 'Do You Love Me?'. It showcases the company's progress in legged dynamic balance.
