学生研究员教机器人导航雷区

在全球前warzones,矿山,在过去的冲突,现在的垃圾中的农村,特别是在农村的农业社区,其中平民经常被杀死或致残倾向于土地残余。 

For the last four years, two Franklin & Marshall College professors and their student-researchers have been part of an international group that designed and built prototype robots that could help begin a more rapid pace at removing an estimated 11,000 mines worldwide.

“We think we can speed things up,” said Teaching Professor of Geosciences Tim Bechtel, director of F&M Science Outreach. 

  • As a Hackman Summer Scholar, DiGregorio conducts research on navigating robots around minefield obstacles. “I came to F&M to do research because it’s such a good school for it, and it sounded like perfect things to do, and I was right,” he says.

Imagine a dozen robots that swarm a minefield to detect and mark mine locations, and do it far faster than soldiers with landmine detectors. NATO funded the first three years of the project, and recently provided another $420,000 grant to the group: scientists from F&M, Italy, Ukraine and Jordan.

“我们正在对机器人的合作团队工作,所以每个组都会有一个,”德尔说。 “我们会努力的事情之一是机器人之间的通信,从而使公司将是比地球和环境多一点物理。”

As a Hackman Summer Scholar, Aaron DiGregorio, a senior physics major, is conducting research on navigating the robot around minefield obstacles with Professor of Physics and Astronomy Fronefield Crawford, the other F&M scientist on the international team.

“我们教它不会撞上树木和岩石移动,并遵循矿到矿之间有明显的路径,以便其他人可以串联遵循” digregorio说。

digregorio与克劳福德的合作从去年开始,并会持续到秋季。

“什么我目前所做的就是测试出来[机器人]使用金属探测器,它的图像地雷如何,以及它如何区分它们,可行性,然后看是否合并的图像将让我们更清晰的图像,” digregorio说。

克劳福德说,前三年的北约程序,在此期间,面包盒大小的机器人建的,专注于开发与能识别水雷传感器的机器人;下一阶段着重于几个机器人,每个都配有一组特定的传感器,彼此跟随。

“我们有三个现在这些机器人的,”克劳福德说。 “第一机器人识别目标,并且所述第二机器人跟随在其路径中,进到该相同的点,然后图像目标。第三机器人来临时,进一步分析用金属探测器对象“。

有几个传感器检测同一对象允许对象的正确识别为危险的东西或无害的东西,比如杂乱,他说。

“Our task at F&M is to think about how these robots can be controlled in a semi-autonomous way, to follow one another in a particular path laid out with flags,” Crawford said. 

The robots operate on software developed by Clear Path, a robot company, but F&M researchers such as DiGregorio work to program the robots to talk to one another and to talk to a GPS-positioning-like master controller that directs them.

As he considers a master’s degree in engineering, DiGregorio said, “I came to F&M to do research because it’s such a good school for it, and it sounded like perfect things to do, and I was right.”
