Abstract: Mitigating the reality gap through optimization of one or more simulated hardware parameters for simulated hardware components of a simulated robot. Implementations generate and store real navigation data instances that are each based on a corresponding episode of locomotion of a real robot. A real navigation data instance can include a sequence of velocity control instances generated to control a real robot during a real episode of locomotion of the real robot, and one or more ground truth values, where each of the ground truth values is a measured value of a corresponding property of the real robot (e.g., pose). The velocity control instances can be applied to a simulated robot, and one or more losses can be generated based on comparing the ground truth value(s) to corresponding simulated value(s) generated from applying the velocity control instances to the simulated robot. The simulated hardware parameters and environmental parameters can be optimized based on the loss(es).

Abstract: A portable collapsible tent includes a cover, a roof frame with a central pole, inclined roof ribs and spreaders, extensible legs, and cross bars. The ribs and spreaders are pivotally and movably jointed at the central pole. A locking unit secures the roof frame when the tent is pitched. Each leg has at one end a fixed corner member that provides a four-way connection and a multi-way support member that movably engages and locks onto the leg to support two cross bars and an inclined rib connected thereto with three diagonal braces. A spring is positioned on the central pole to enable the collapsed tent to be opened easily. A lateral projecting foot member enables each leg to be anchored on the ground. Reinforcement ropes further secure the tent to the ground via the four-way connectors. The portable collapsible tent can be easily set up and collapsed without tools and has a strong structural integrity, able to withstand substantial stress and direct/indirect forces.
