Widespread adoption of modern robots in alllife spheres is impossible without the training of mechanical assistants to independently move in any conditions. Swiss engineers managed to improve the original Ascento robot, which has a unique kinematic scheme, giving it high stability even after a collision with fast-moving objects. A detailed description of the Swiss innovations will be presented at the events of the Paris Conference International Conference on Robotics and Automation (ICRA) 2020, scheduled for late May.
Ascento's uniqueness lies in its usehybrid mechanisms of movement: wheels and multi-section mechanical legs. The robot has two three sectional legs at the ends of which are wheels of large diameter. This scheme allows the robot to combine fast movement with wide functionality.
Four “help” keep the balanceelectric motors: two are located in the wheels and two at the junction of the Ascento case with mechanical legs. Each leg of the robot is independent of the other and works according to an individual scheme. To maintain the robot in equilibrium, torsion springs are used, which are placed at the junction of the two main leg sections and supporting them in a bent state.
During a demonstration at last year’s conferenceThe ICRA robot has shown good examples of various modes of movement, including jumping onto an obstacle and climbing after a fall. However, the robot algorithm turned out to be imperfect, which limited its further use. However, the use of the new algorithm literally put Ascento on its feet and gave it resistance to external mechanical influences. Now the robot can compete with the famous two-wheeled brother Boston Dynamics Handle.
Judging from the demo presentedAscento is able to maintain balance with varying degrees of extension of the leg sections. In this case, the robot is able to move around, leaning with wheels on a surface of various heights, or move along an inclined surface. Also, in a standing position, the robot can maintain balance on one wheel during the forced lifting of the second, or when the second leg accidentally falls into a hole on the road.
During a turn, to maintain balance,the robot was able to tilt the body. However, the most significant innovation was the ability to withstand Ascento external shock mechanical stress. The video shows that a water bottle thrown into the robot could not knock it over.
An important feature of the robot is the abilitywork offline using on-board sensors and sensors. Ascento is currently able to independently develop a three-dimensional map model of the room.
