    摘要:

    為保證配送機器人能夠安全穩定的將實(shí)驗樣品送達至指定位置,利用FA-A*優(yōu)化算法,從硬件和軟件兩個(gè)方面優(yōu)化設計實(shí)驗樣品配送機器人控制系統。改裝配送機器人位姿傳感器、數據處理器、電機驅動(dòng)器和控制器等設備元件,調整系統電路的連接方式,完成硬件系統的優(yōu)化。采用柵格法搭建配送機器人移動(dòng)環(huán)境模型,通過(guò)圖像采集、特征提取與特征匹配等環(huán)節,識別實(shí)驗樣品配送對象的具體位置。以實(shí)驗樣品當前位置為起點(diǎn)、配送終端位置為終點(diǎn),利用FA-A*優(yōu)化算法規劃機器人配送路徑,結合機器人實(shí)時(shí)位姿的跟蹤結果,計算機器人控制量,最終從位置/速度、平衡、自主搭乘電梯等方面,實(shí)現配送機器人的控制功能。通過(guò)系統測試實(shí)驗得出結論:綜合靜態(tài)障礙物和動(dòng)態(tài)障礙物兩個(gè)實(shí)驗場(chǎng)景,與傳統控制相比,在優(yōu)化設計系統控制下,配送機器人的位置和速度控制誤差分別降低約14m和0.38m/s。

    Abstract:

    To ensure that the delivery robot can safely and stably deliver experimental samples to the designated location, the FA-A * optimization algorithm is used to optimize and design the control system of the experimental sample delivery robot from both hardware and software aspects. Modify equipment components such as pose sensors, data processors, motor drivers, and controllers for the delivery robot, adjust the connection method of the system circuit, and complete the optimization of the hardware system. Build a mobile environment model for the delivery robot using the grid method, and identify the specific location of the experimental sample delivery object through image acquisition, feature extraction, and feature matching. Starting from the current position of the experimental sample and ending at the delivery terminal, the FA-A * optimization algorithm is used to plan the robot"s delivery path. Combined with the real-time tracking results of the robot"s posture, the robot"s control amount is calculated. Finally, the control function of the delivery robot is achieved from aspects such as position/speed, balance, and autonomous elevator riding. Through system testing experiments, it was concluded that, compared to traditional control, the position and speed control errors of the delivery robot were reduced by approximately 14m and 0.38m/s respectively under the optimized design system control, combining static and dynamic obstacle experimental scenarios.
