A drive device 10 includes a center pulley 12 that is rotatable about a center axis X, a motor 14, a spiral spring 16 serving as an energy storage part, an output part 18, and a lock mechanism 20. A first end 16A of the spiral spring 16 is fixed to the center pulley 12. Rotation of the center pulley 12 by the motor 14 in a first direction causes the spiral spring 16 to extend and store energy. When the stored energy is released, the spiral spring 16 contracts and moves around the center axis X such that a second end 16B approaches the first end 16A. The output part 18 rotates in association with the movement of the spiral spring 16. The lock mechanism 20 is switchable between a lock state that restricts movement of the spiral spring 16 and a lock release state that allows the spiral spring 16 to move freely.

A prediction system predicts power demand of each of one or more facilities configured to produce a product. The prediction system includes: a calculation unit configured to calculate, for each of the one or more facilities, a scheduled power usage amount in a target time slot, based on actual result data of consumed power and a production plan of the product; and a determination unit configured to determine, for each of the one or more facilities, a scheduled power purchase amount from a power system in the target time slot, based on the scheduled power usage amount and a power trading price in the target time slot. Thereby, the prediction system can provide information capable of improving a merit for a consumer obtained by cooperating on a request for a demand response.

This invention realizes a communication device capable of outputting notification information in some cases, even if a reception error occurs in communication with a slave unit. A communication device (10) comprises: a determination unit (70) that determines whether there is a reception error in frame data demodulated by a reception unit (40); and a control unit (60). If a determination result is obtained indicating that there is a reception error, the control unit (60) uses demodulated first additional information to examine whether there is an error in demodulated notification information, and outputs the demodulated notification information if an examination result is obtained indicating that there is no error.

Provided are a method, a system, and a mobile robot for generating an environment map, each configured to generate a wide and highly accurate environment map at low cost and in a short time. A method according to an aspect of the present invention is a method of generating an environment map by controlling a first mobile robot that is movable and provided with a first detection unit for detecting an environment and generating first environment information and a second mobile robot that is movable and provided with a second detection unit for detecting the environment and generating second environment information. The method includes: causing the first mobile robot to move; generating first environment information by causing the first detection unit of the first mobile robot to detect an environment while the first mobile robot is moving; causing the second mobile robot to move so as to follow the first mobile robot; generating the second environment information by causing the second detection unit of the second mobile robot to detect an environment while the second mobile robot is moving; and generating an environment map based on the first environment information and the second environment information.
