Abstract: A rotatable tray mechanism includes a base, a rotatable tray, and a revolute pair assembly and an actuating unit arranged between the base and the rotatable tray. At least one of the rotatable tray and the base includes a revolving shaft arranged on at least one edge. The revolute pair assembly is arranged on at least one of the base and the rotatable tray and is at a location opposite to the revolving shaft. One revolving shaft mates with at least one revolute pair assembly including a revolute pair and an enable mechanism, wherein the revolute pair has a first state and a second state. The enable mechanism is enabling the revolute pair to switch over between the first state and the second state. When the revolute pair is in the first state, the rotatable tray rotates with respect to the base by taking the revolving shaft as a rotating shaft and taking the revolute pair as support of the revolving shaft when the actuating unit applies an acting force, wherein the direction of the acting force applying the rotatable tray is a direction far away from the base.

Abstract: Provided are an adjusting base and a self-driven robot. The flexible base includes: a chassis, a carrying plate and an adjusting mechanism. The bottom of the chassis is provided with at least one second driven wheel and at least two driving wheels. The bottom of the carrying plate is provided with at least a first driven wheel. The adjusting mechanism is configured to connect to the carrying plate and the chassis or connect to the carrying plate and the second driven wheel. When the ground is uneven, the adjusting mechanism is configured to dynamically adjust the second driven wheel in such a manner that the first driven wheel, the second driven wheel and the driving wheels are in contact with the ground.
