A brief note about Boston DynamicsBostonDynamicsIn 1992, Marc Raibert, a professor at MIT, founded Boston Dynamics. At that time, Marc Raibert was 47 years old, a typical genius maker who was dragged down by teaching. When Boston Dynamics was first established, it served the US military and provided robot design services. It was later acquired by Google X in 2013. After rumors with Toyota and Amazon, it was sold to SoftBank in June 2017. It has now become the world's number one robot company. After videos of Boston Dynamics’ robot products were posted on YouTube, they quickly became popular and gained a group of fans around the world. The bionic robots BigDog and Spot, and the humanoid robot Atlas have all become Internet celebrities. Quadruped robots: BigDog, Little Dog , AlphaDog, Cheetah, WildCat, Spot/SpotMini BigDog (Big Dog) Born in 2005, its full name is "Infantry Squad Support System" and its nickname is Big Dog. It has four legs that can move freely, is about 3 feet (about 0.9 meters) long, 2.5 feet (about 0.76 meters) high, weighs 240 pounds (about 109 kilograms), and is about the size of a donkey. It is not afraid even when running around in a sea of fire, and is very similar to the "walker" chariot used by the army of the neighboring country in "Star Wars". Big Dog's engine is driven by a hydraulic system. Its four legs have joints like animals, which can absorb shocks and recover part of the energy with each step to drive the next step. In addition, Big Dog's onboard computer can control body movement and process sensors, and can also handle communications. Its control system maintains body balance and selects different movement and navigation methods in different terrains. Therefore, it can adapt to complex terrain conditions and can walk, run, climb and carry heavy objects. Its main task is to help marines carry equipment during marches. Big Dog can run at a speed of 4 miles per hour (about 6.4 kilometers per hour), with a maximum climbing gradient of 35 degrees. It can walk on ruins, mud, snow, and water, and can carry 340 pounds (about 154 kilograms).

Researchers use it to explore the basic relationship between kinematics, dynamic control, environmental perception and movement in complex terrain. Each leg of Little Dog is driven by three motors, with a very large range of movement, able to climb slopes and achieve dynamic movement gaits. Little Dog's sensors are mainly responsible for measuring joint angles, motor current, body balance and ground contact conditions. The onboard lithium battery can ensure 30 minutes of continuous operation. And through wireless communication and data acquisition systems, remote control and data analysis can be performed.

The planned system will carry a load of 400 pounds and can walk 20 miles in complex terrain. The video shows early results from the laboratory, where the prototype is controlled by remote control. The Alpha Dog is designed to draw power from an internal combustion engine and is ten times quieter than the BigDog. The field version of the AlphaDog has a head equipped with a terrain sensor.
>>AlphaDog Proto Related Videos Cheetah Claiming to be faster than Bolt, Cheetah can run at speeds of up to 28.3 mph (45 km/h), breaking the previous record of 13.1 mph (21 km/h) set by an MIT robot in 1989. The back structure of the Cheetah robot is articulated, which allows it to move back and forth flexibly with every movement, increasing its stride and running speed, which is not much different from the movement principle of animals. Its driving force comes from an external hydraulic pump. However, compared with the products mentioned above, Cheetah has less autonomy and requires human intervention when it moves.

Although its speed is not as fast as Cheetah, this four-legged robot can run at a speed of 16 miles per hour (about 25 kilometers per hour) regardless of the terrain it encounters. In addition, it can jump and turn quickly.
>>WildCat Related Videos Spot/SpotMini Spot is a dog-shaped robot for family nannies launched by Boston Dynamics. It is a "soft" four-legged robot with very flexible legs and a weight of 160 pounds. It can move freely in indoor and outdoor terrains. SpotMini is a smaller version of Spot, weighing only 65 pounds, and it also has a robotic arm. From the outside, SpotMini looks like a skeleton version of a giraffe. This robotic arm is very flexible, and the robot can use it to grab and move objects. SpotMini has also done a good job in terms of silence. Because the legs are very flexible, the Spot series robots can even crawl under the table. Finally, Spot's automation is also quite high through the sensors it carries with it.

It is based on the company's early PETMAN humanoid robot research and development (PETMAN can balance itself and walk freely, bend its body, and even do calisthenics, so it is used to test chemical protective clothing and simulate how soldiers use protective clothing under real conditions), and has undergone four generations of revisions.
PETMAN The main feature of the first version is that Atlas needs a long line for power supply, and can walk on a road paved with stones in a laboratory environment and keep its body balanced without falling. Secondly, in a laboratory environment, let Atlas stand on one foot and introduce external impact. When the impact force is not very large, Atlas can still stand on one foot without falling - it can "stand on one leg". When walking on the track, place an obstacle on the path of one foot. When Atlas steps on the obstacle, it will automatically update its gait in the next step and plan the next landing point to leave the obstacle. Finally, we conducted a walking experiment in the wild environment, where Atlas can maintain a good balance. At the beginning of 2015, in order to participate in the DARPA Robotics Challenge in early June, Atlas completed its own evolution. This time, it was freed from the constraints of cables, and its body was slimmer and smaller. The more effective onboard hydraulic pump also made the Atlas robot move faster. Its power supply system is an onboard 3.7 kWh lithium-ion battery pack, which can last for an hour when completing actions including walking, standing and using tools. The powerful hydraulic pump allows Atlas to get up by itself when it falls. The third version of Atlas can be operated indoors and outdoors. However, like the power of the second version, Atlas still uses power supply and hydraulic drive. The sensors inside its body and legs collect posture data to keep its body balanced. The lidar locator and stereo camera on its head can enable Atlas to avoid obstacles, detect ground conditions and complete cruise tasks. This version of Atlas is 1.75 meters tall and weighs 82 kilograms, which is lighter than before. In the process of moving boxes, going out and pushing the door, it is necessary to mark points to complete the object recognition task. The machine vision capabilities such as object recognition need to be improved, and it has become more efficient to climb up by itself. In November 2017, Boston Dynamics released a video of the latest version of Atlas. This time, Atlas showed a more powerful skill: backflip. The improved Atlas completed a series of actions such as jumping, spinning and backflipping, and was able to stand firmly after each action, just like a gymnast.

Handle is about 6.5 feet tall (about 2 meters), travels at a speed of 9 miles per hour, and has a vertical jump height of 4 feet (about 1.2 meters). The electric power runs the electronic and hydraulic drive, and the range of a single charge is about 15 miles (1 mile = 1.6 kilometers). The main feature of the Handle is to carry heavy objects. It can lift heavy objects on the ground with its twisting arm. It can bear 45.5 kg, and the robot can still jump over obstacles lightly when carrying a load. In addition, Handle's athletic ability is also enviable. It can not only turn around quickly, but also go down the stairs quickly with its back turned, and slide down the snow slope easily. According to Boston Dynamics, Handle uses many dynamics, balance, and mobile control principles, which the company has previously used to build quadrupedal and bipedal robots, but this robot has only 10 drive joints. It is less complicated than previous robots. The wheels can slide quickly on a horizontal plane, but Handle can also use its legs to go anywhere. In other words, Handle, which has both wheel and leg functions, can learn from the best of both worlds. However, this seems to have more or less deviated from its original intention and become in line with the aesthetic of its old employer Google, which is "simple and easy to use." "Wheels are a great invention. But wheels only work well on flat ground, while legs can go anywhere. By combining wheels and legs, Handle has the advantages of both wheeled robots and legged robots," said Marc Raibert, founder of Boston Dynamics, in an interview with IEEE Spectrum.

Almost any terrain can't stop it. In addition to crossing various complex terrains, it can also perform tasks in humid areas because it is fully sealed and waterproof. In addition, the special anti-impact design allows it to be safe even if it falls off a cliff. RHex is equipped with cameras on the front and back, and the operator can control it from 2,300 feet (about 700 meters) away.
