Description

Irregularity Forming Robot The present invention relates to a surface-forming robot, and more specifically, to a robot that forms surface irregularities on a concrete surface during curing through autonomous driving. The contents presented in this section are intended merely to provide background information for the present invention and do not constitute prior art. Before pouring concrete, it must be verified that reinforcing bars, piping, etc. are properly placed by referring to the construction detail drawings and concrete fabrication assembly drawings. In principle, concrete must be poured continuously within the section. However, it is desirable to limit the concrete pouring thickness to 40 to 50 cm or less. This is because if the concrete pouring thickness exceeds 50 cm, a long time is required for curing, and the quality of curing deteriorates. When pouring concrete with a thickness exceeding 50 cm, the concrete may be poured in divided sections. In this case, cracks must not occur between the divided poured concrete sections; to prevent cracking between the divided concrete sections, it is necessary to intentionally form irregularities on the contact surface of the concrete. According to conventional technology, it was common practice to form irregularities by a person using a tool to scratch the poured concrete. As a technology related to the present invention, the equipment for creating an uneven surface on a bridge concrete slab, disclosed in the Korean Registered Patent Publication, comprises a vibration motor, a horizontal adjustment plate, a rotary motor, a driving wheel, an uneven wheel, and a gravity weight. Although this related technology has a similar purpose to the present invention, it is distinguished from the present invention in its driving method and differs from the configuration and effects of the present invention due to the disadvantage that autonomous driving is impossible.
