Boston Dynamics’ Robot is back, now navigate entire offices by itself and even climb stairs

In February, we wrote about the newest futuristic robot from BostonDynamics called SpotMini. Back then, the robot was learning how to open doors for his “friends.” SpotMini is back, now it can navigate entire offices by itself. It can even climb stairs. Now Spot can navigate an entire office, stairs and all, without human guidance.

SpotMini is a small four-legged robot that comfortably fits in an office or home. It weighs 25 kg (30 kg if you include the arm). SpotMini is all-electric and can go for about 90 minutes on a charge, depending on what it is doing. SpotMini is the quietest robot we have built.

SpotMini inherits all of the mobility of its bigger brother, Spot, while adding the ability to pick up and handle objects using its 5 degree-of-freedom arm and beefed up perception sensors. The sensor suite includes stereo cameras, depth cameras, an IMU, and position/force sensors in the limbs. These sensors help with navigation and mobile manipulation.

In the video below, SpotMini autonomously navigates a specified route through an office and lab facility. Before the test, the robot is manually driven through the space so it can build a map of the space using visual data from cameras mounted on the front, back and sides of the robot.

During the autonomous run, SpotMini uses data from the cameras to localize itself in the map and to detect and avoid obstacles. Once the operator presses ‘GO’ at the beginning of the video, the robot is on its own. Total walk time for this route is just over 6 minutes. (The QR codes visible in the video are used to measure performance, not for navigation.)

Below is another video of SpotMini and its “friend” walking around the house, and even doing some household chores.

SpotMini is a new smaller version of the Spot robot, weighing 55 lbs dripping wet (65 lbs if you include its arm.) SpotMini is all-electric (no hydraulics) and runs for about 90 minutes on a charge, depending on what it is doing. SpotMini is one of the quietest robots we have ever built. It has a variety of sensors, including depth cameras, a solid state gyro (IMU) and proprioception sensors in the limbs. These sensors help with navigation and mobile manipulation. SpotMini performs some tasks autonomously, but often uses a human for high-level guidance. For more information about SpotMini visit our website at www.BostonDynamics.com
