The XRP robots have simple, inexpensive, easy-to-build platforms that are just as programmable as far more expensive robots; they also come with built-in educational and software support, are designed to operate autonomously, perform basic tasks, navigate on their own, sense distance, and manipulate their environment. The XRP’s tool-free assembly allows for a quick build, and parts can be replaced easily by a 3-D printer. When they come to market next year, they will measure 7×5 inches, weigh less than one pound—about the size of a box of chocolates—and cost less than $50. With the kits, educators and students also get access to free online courses, created and supported by WPI, on how to build, program, and control the robot, which they can scale up using the same hardware with free software updates.
“Based on the overwhelmingly positive feedback that we’ve received here in Geneva, we know that STEM educators, mentors, and trainers recognize the potential that these XRP kits have for introducing young people to STEM— and to the power it unleashes within them,” said Interim President Winston “Wole” Soboyejo. “The global appeal of the XRP is important because we cannot solve the world’s great problems without a diversity of STEM professionals with different insights and experiences working together. WPI and our long-term partners at DEKA created the XRP to address that critical diversity gap. The XRP will help to address the lack of access to hands-on STEM education opportunities among less-well-off populations, thereby expanding and filling the global STEM education pipeline so that we can spark more imaginations and ignite more flames of curiosity that will help with the important work of addressing global needs.”
The idea for the XRP robots’ stem from the early days of the COVID-19 pandemic when WPI students abruptly switched to remote learning in spring 2020 and FIRST needed to keep competitive robotics teams working together on various entries. Both WPI and FIRST needed to figure out how to get remote students small, relatively inexpensive robots to work on for hands-on experience. Eventually, WPI incorporated a commercially available robot kit that students could purchase and build at home into its curriculum. A similar version was then used in FIRST robotics competitions—one that was able to use WPILib software, which the WPILib software development team created for FIRST teams in 2009. From there, collaborators from WPI and DEKA created the XRP with support from the NSF through Engineering For Us All (E4USA).
“Unveiling the XRP and sharing them with the teams and their mentors was a validating experience,” said Brad Miller. “A lot of thought and consideration went into creating every aspect of that platform, and what we heard was almost like a collective sigh of relief. This is not like anything else that exists, and you can’t go online to order something similar at this price point. We heard expressions of gratitude, and requests for speed. People were telling us they needed thousands more of these made—and fast, which was only surprising in the sense of magnitude; we knew educators and mentors wanted an affordable, high-quality STEM education tool, but we didn’t realize just how much.”
While the initial XRP robots were produced using 3-D printers, larger scale manufacturing will be needed to meet demand. In the coming weeks, WPI and DEKA will work to finalize details and work through logistics with the goal of producing a large number of XRPs by April 2023 in time for the FIRST Championship.
