An underwater caterpillar vehicle has been designed and developed to profile along the beach and shoreface. This prototype is employed for zones that are unsuitable to study through bathymetry or manual measurements. The system consists of a metallic structure propelled by two caterpillar tracks. An electronic accelerometer and a GPS receiver measure the profile data. These components provide the seabed slope and the traveled distance along a path. The data are recorded locally and transmitted to a host computer with a radio modem, conforming a wireless duplex link, which is also used for controlling the vehicle and reporting the status. The profiler system has been tested in several zones in the Pacific Coast of the Baja California Peninsula, Mexico and the results were compared with an Electronic Total Station. Based on the obtained results, the underwater caterpillar system evinces to be a reliable profiler option.

水下卡特彼勒剖面仪

设计和开发了一种水下履带式车辆，用于沿着海滩和岸面进行剖面测量。该原型用于不适合通过水深测量或手动测量进行研究的区域。该系统由一个由两条履带推动的金属结构组成。电子加速度计和 GPS 接收器测量轮廓数据。这些组件提供海床坡度和沿路径行进的距离。数据在本地记录并传输到带有无线电调制解调器的主机，符合无线双工链路，也用于控制车辆和报告状态。该剖面仪系统已在墨西哥下加利福尼亚半岛太平洋海岸的多个区域进行了测试，并将结果与​​电子全站仪进行了比较。根据得到的结果，
