The world is changing once again forever. The invasion of robots is right around the corner, and it heralds yet another powerful chapter in the upcoming artificial intelligence revolution. It is now reported that over 3.5 million industrial robots are installed already, which is more than the population of every US city except New York and Los Angeles, according to the International Federation of Robotics. First, about 200-500 billion parcels move around the world every year, depending on how you count them. One of the leaders in the space of robotics is Boston Robotics, staffed by Indian engineers, and now owned 80% by Hyundai.

Mobile manipulators for indoor human environments can serve as versatile devices that perform a variety of tasks, yet adoption of this technology has been limited. Reducing size, weight, and cost could facilitate adoption, but risks restricting capabilities. We present a novel design that reduces size, weight, and cost, while supporting a variety of tasks. The core design consists of a two-wheeled differential-drive mobile base, a lift, and a telescoping arm configured to achieve Cartesian motion at the end of the arm. Design extensions include a 1 degree-of-freedom (DOF) wrist to stow a tool, a 2-DOF dexterous wrist to pitch and roll a tool, and a compliant gripper. We justify our design with anthropometry and mathematical models of static stability. We also provide empirical support from teleoperating and autonomously controlling a commercial robot based on our design (the Stretch RE1 from Hello Robot Inc.) to perform tasks in real homes.

Almost exactly a year ago, Boston Dynamics introduced a new robot called "Stretch." It's not quite as exciting or as terrifyingly adorable as the Hyundai-owned company's Spot robotic dog, but it can make loading, unloading and moving boxes in warehouses a lot easier. Now, Boston Dynamics has announced that Stretch is finally available for purchase. Or, more precisely, it's now accepting reservations for deliveries in 2023 and 2024, because it's sold out throughout the year due to strong pre-order demand. One of the early Stretch customers is DHL, which signed a $15 million deal with Boston Dynamics to equip its warehouses in North America with the robots over the coming years. TechCrunch says Gap and H&M are equipping their warehouses with the robot, as well.
