Provided are methods and systems for aligning multiple parts using simultaneous scanning of features of different parts and using feature-based coordinate systems for determining relative positions of these. Specifically, a feature-based coordinate system may be constructed using one or more critical dimensions between features of different parts. The scanner may be specifically positioned to capture each of these critical dimensions precisely. The feature-based coordinate system is used to compare the critical dimensions to specified ranges. The position of at least one part may be adjusted based on results of this comparison using, for example, a robotic manipulator. The process may be repeated until all critical dimensions are within their specified ranges. In some embodiments, multiple sets of features from different parts are used such that each set uses its own feature-based coordinate system. The part adjustment may be performed based on the collective output from these multiple sets.

Disclosed are a movable battery replacing platform (103) and a quick replacing system (100), wherein the movable battery replacing platform (103) comprises: a travel-driving portion (106) used for driving the movable battery replacing platform (103) to move on the ground; a lifting portion (107) mounted on the travel-driving portion (106), for lifting a battery during the replacement of the battery; and a battery mounting portion (108) mounted on the top of the lifting portion (107), for placing a battery to be replaced or a replaced battery, wherein the battery mounting porting (108) is provided with a battery replacing device. The device can use an unlocking device (50) to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The whole process is fully automated without manual intervention and can improve battery replacement efficiency. In addition, the angle of an upper board (10) relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform (103) remains still, so as to further improve unlocking efficiency.

A bladder assembly including an inflatable bladder having an elongated body defining an internal volume, the body being formed as a layered structure that includes an elastomeric layer defining an interior surface of the body, a friction-reducing layer defining an exterior surface of the body, and a jacketing layer positioned between the elastomeric layer and the friction-reducing layer, and a pressurized fluid source in selective fluid communication with the internal volume of the body.
