The present technology relates to a moving body and a control method capable of improving affinity of the moving body for a person and a space. A moving body according to one aspect of the present technology includes a top plate that serves as a desk at which a person performs work, a support arm that supports the top plate and that can extend and contract, and a moving unit that holds the support arm and performs movement for causing the work to be performed. Furthermore, the moving body controls a posture state including a state of the support arm and a movement state of the moving unit in accordance with a relationship with an environment state as a state of a surrounding environment and a person state as a state of the person located around, sensed by a sensor. The present technology can be applied to a movable robot.

A modularized fast assembly lift desk includes a preassembled module, a matched module and a clamping member. The preassembled module (100) includes a combined body formed by connection between a desktop platform and a transverse beam. The matched module includes a lift column including a motor housing. The clamping member includes a fixed connecting end and a movable squeezing end. When a user assembles the lift desk, the fixed connecting end of the clamping member is engaged with the preassembled module. The movable squeezing end of the clamping member is pressed to generate a squeezing force between the movable squeezing end and the motor housing. The motor housing and the preassembled module are fixedly connected to implement locking between the preassembled module and the matched module.
