After walking untethered in a forest, a new Atlas humanoid robot walks in a forest, untethered, on snow. The new version is electrically powered, hydraulically actuated, sensors to balance and LIDAR and stereo sensors in its head to avoid obstacles. The new Atlas is about 175 cm tall and weighs 82 kg.
Boston Dynamics, a subsidiary of Alphabet, has released their newest robot prototype: Atlas. The robot can walk in tough conditions, lift heavy boxes, and stand up after being knocked down.
The next-gen Atlas from Boston Dynamics is impressive-- strong and capable, it can react to changing environments while achieving its task. When Alphabet (then Google) bought Boston Dynamics, it seemed to be taking away from future robot armies-- far from it.
The humanoid robot Atlas balancing on a line contact (plywood edge approx. 2cm thick). This video was recorded during a lucky run, usually the robot is not able to maintain balance for this long. The shaking is caused by poor state estimation (we only use onboard sensors). The control algorithm is developed by IHMC the robot was build by Boston Dynamics.
The Atlas Humanoid walking over small and partial footholds such as small stepping stones or line contacts. After each step the robot explores the new foothold by shifting its weight around its foot. To maintain balance we combine fast, dynamics stepping with the use of angular momentum (lunging of the upper body). The control algorithm was developed at IHMC, the robot was build by Boston Dynamics.
What have you been up to lately, Atlas?
Atlas does parkour. The control software uses the whole body including legs, arms and torso, to marshal the energy and strength for jumping over the log and leaping up the steps without breaking its pace. (Step height 40 cm.) Atlas uses computer vision to locate itself with respect to visible markers on the approach to hit the terrain accurately.
Atlas humanoid walking with straighter legs. Control algorithm by IHMC Robotics. The height of the robot is left uncontrolled in the whole-body controller, but the knee angles are specified in the null-space of the other task objects. This allows the robot to balance laterally while standing straight up. Published in ICRA 2018, "Straight-Leg Walking Through Underconstrained Whole-body Control."
Atlas humanoid robot (DRC version) walking across narrow terrain using autonomous planning. The robot senses the terrain with LIDAR and builds a map of planar regions. A path planning algorithm plans footsteps across the planar regions to a goal location, specified by an operator. The robot is currently about 50% successful over this type of terrain. We plan to increase the rate of success by adding balance using angular momentum and by better considering joint ranges of motion. Narrow terrain is difficult due to the need to do some "cross-over" steps, which are tricky due to limited range of motion in the hip joint, and also due to having a small polygon of support when one foot is directly in front of the other.

Atlas uses its whole body -- legs, arms, torso -- to perform a sequence of dynamic maneuvers that form a gymnastic routine. We created the maneuvers using new techniques that streamline the development process. First, an optimization algorithm transforms high-level descriptions of each maneuver into dynamically-feasible reference motions. Then Atlas tracks the motions using a model predictive controller that smoothly blends from one maneuver to the next. Using this approach, we developed the routine significantly faster than previous Atlas routines, with a performance success rate of about 80%.
The latest footage from Boston Dynamics is, unsurprisingly, both impressive and terrifying. Over the past few years we've seen Atlas navigate uneven terrain and even jump around a parkour course. This is on another level, though. The bipedal robot does a handstand, rolls around and even does a few jumping twists -- all without losing its balance.
This video is a comedic parody and is not in anyway associated with the actual Boston Dynamics Robotics Company.

Big ups to Xsens!
Parkour is the perfect sandbox for the Atlas team at Boston Dynamics to experiment with new behaviors. In this video our humanoid robots demonstrate their whole-body athletics, maintaining its balance through a variety of rapidly changing, high-energy activities. Through jumps, balance beams, and vaults, we demonstrate how we push Atlas to its limits to discover the next generation of mobility, perception, and athletic intelligence.
Go behind the scenes at Boston Dynamics with the Atlas Team as we work to train multiple Atlas robots to maneuver their way through our most complex parkour course yet. The team pushes Atlas to its limits to discover the next generation of mobility, perception, and athletic intelligence.
