Humanoid robots may be capable to run, dance, and infrequently kick people, however to grow to be really human, they’re going to wish to learn to do all types of menial chores at work.
Flexion Robotics, a Swiss startup based by ex-Nvidia robotics researchers, thinks it has the answer. The corporate has developed a method to practice robots to carry out complicated duties that contain easy expertise like opening doorways, climbing stairs, and carrying containers. The bottom line is to show the robots particular person expertise in simulation, then have a grasp AI algorithm decide tips on how to use them.
Most demo movies present humanoids which were skilled to do a selected job, like folding shirts or loading cabinets. Sometimes, that is achieved by way of teleoperation—an individual behind the scenes who controls the robotic’s actions. However this method doesn’t work reliably when the robotic is put into unfamiliar settings. Flexion says its system is totally different—and extra environment friendly—as a result of it trains its robots in simulation and with restricted human instruction.
The video under reveals the software program in motion: A modified Unitree humanoid robotic operates autonomously after it receives the next command: “A parcel with snacks has been delivered for Flexion. Retrieve it utilizing the steps and are available up utilizing the elevator. Then unpack it and place the objects into the empty drawer on the shelf within the snack space.”

Flexion’s method works by combining totally different AI methods.
The primary AI mannequin figures out tips on how to do its chores by digesting movies of people doing various things. The software program then matches realized expertise—which it has picked up in simulation—to the movies and performs these duties in the actual world. As a way to attain the mail room in an workplace, for instance, the mannequin could have realized that it must open sure doorways and use the elevator. The system additionally controls the robotic’s motors, permitting it to stroll, transfer its limbs, and preserve steadiness.
In keeping with Nikita Rudin, the cofounder and CEO of Flexion and a former robotics analysis scientist at Nvidia, the software program’s “secret ingredient” is its intensive use of reinforcement studying, which trains computer systems to grasp duties by way of trial and error. Every layer of the software program, from the grasp AI mannequin to the simulation to the motor management, makes use of this method.
