Shot peen forming (or SPF) and Shot peening (or SP) and are extensively applied in aerospace and transportation engineering to, respectively, form curved shapes from sheet metal (which would be difficult to form with traditional methods like stamping) and improve mechanical properties of the surfaces. Despite a wide range of their applications, many SPF and SP processes are currently executed mostly manually or in an open-loop fashion by qualified operators. The reach, repeatability, accuracy, and response time of the processes are then obviously limited by those of the operator. A robotic system seems to offer an attractive substitute addressing the aforementioned issues. However, the application of robots in such applications is hindered by the process uncertainties which limit the accuracy, repeatability, and response time of automated solutions. For instance, several trials to reach the desired forming are common to many SPF processes. Two main sources of uncertainty, tackled in this project, include the nozzle's motion (position and velocity) and peening coverage.

喷丸成形(或SPF)和喷丸(或SP)分别被广泛应用于航空航天和运输工程中，以分别由板材成形曲面形状(使用传统的冲压方法很难成形)和改善表面的机械性能。尽管它们的应用范围很广，但许多SPF和SP工艺目前大多是手动执行或由合格的操作员以开环方式执行。因此，过程的可达性、重复性、准确性和响应时间显然受到操作员的限制。机器人系统似乎为解决上述问题提供了一个有吸引力的替代品。然而，机器人在这类应用中的应用受到工艺不确定性的阻碍，这些不确定性限制了自动化解决方案的准确性、重复性和响应时间。例如，达到所需成形的多次试验在许多SPF工艺中是常见的。在这个项目中，解决了两个主要的不确定性来源，包括喷嘴的运动(位置和速度)和喷丸覆盖范围。
