Knight Rover Robotics
When you want to learn about robotics where do you begin?
The Mind Project is launching its new “Knight Rover Robotics Initiative” with the goal to generate a robotics kit with low-cost, readily available hardware, a suite of innovative software, and instructional materials pitched at every level of expertise from novice to experienced programmer.
The heart of Knight Rover is the open source software “RObotics Orchestration Kit” (ROOK for short) created by Eric Thill, who has been the leader of The Mind Project robotics team since he was a sophomore at Illinois State in 2008. ROOK is being created for use in educational settings and so that it will allow students to engage with the software regardless of their level of expertise. At the most basic level, students learn to use the software to make a robot perform certain behaviors. The deeper they dig the more they will learn about computer programming and the greater freedom they will achieve to re-write and expand the computational systems controlling their machine.
Like all of our physical robot projects, this one is designed to complement our “virtual” robotics labs and our other online curriculum in AI and robotics. How this robot project will integrate with specific online modules will be discussed below.
I. THE ROBOT
KR 1.0 (Knight Rover Version 1)
The ROOK software is remarkably flexible and can be used to control a wide range of different types of robotic hardware. We have chosen to build our first Knight Rover robot (KR 1.0) using the GoPiGo hardware platform from Dexter Industries, which is relatively inexpensive and readily available.
The hardware kit uses basic sensors, motors, and other components along with a Raspberry Pi as its central processing unit (its “brain”). The team is working to add new hardware capabilities (sensors and end-affectors) and to develop code that will expand its "cognitive" powers.
The "KR 1.0 Development Page" will document the teams progress.

II. THE OBJECTIVES
The Mind Project’s primary focus is on the creation of interactive, online curriculum modules that introduce cognitive science – the interdisciplinary study of cognition (mental activity, both biological and mechanical) – to students with no previous background. Many teachers (and their students) lack either the time or the resources to work with physical robots (they are both expensive and time-consuming) and so we have created “virtual” robotics labs and online robotics instruction to help students learn about artificial intelligence and robotics online.
Working on a virtual lab for a couple hours is not the same as working with a physical robot, however. Our goal is to offer the best possible resources for teachers who have used our virtual labs and are ready to move on to the real thing.
Robots are not all designed in the same way, with the same “architecture.” While today’s cutting edge AI and robotics systems use a wide range of different approaches to achieve machine intelligence, a good starting point for understanding robotic architecture is to get some hands-on experience working with two fundamentally different kinds of robot: “top-down” robots and “bottom-up” (or "behavior-based") robots.
We have two virtual robotics labs that introduce students to these two types of robotic design:
One of the first goals for this team is to produce a robot built on the "behavior-based" architecture. Rodney Brooks of MIT was an earlier developer and advocate of this approach, when it was completely ignored by most prominant roboticists. This page has a video in which Brooks explains his inspiration:
The best introduction to behavior-based robots is to design one yourself! In only 20 minutes engaging with our virtual behavior-based lab you will design a number of different robots and begin to understand how a relatively small number of "stupid" simulus-response behaviors, when arranged in a hierarchy (what Brooks calls a "subsumption architecture") can produce remarkably intelligent behavior. This lab, created by Ken Livingston and Josh de Leeuw (at Vassar College), has a brief one-page introduction and a way to design-your own robot to try to replicate the behavior of the robot in the target video.
III. KNIGHT ROVER STUDENT ON NATIONAL TELEVISION
Vivek Abraham was 11 years old when he joined The Mind Project's Knight Rover Robotics team which had, up until then, been open only to college students. Vivek and his friend Tucker Carlson-Huber (age 13) were not being sufficiently challenged by the curriculum in their schools and wanted to join the team. Since the goal of the Knight Rover project is to create learning experiences not only for college students, but also for high school and middle school students its seemed a great opportunity to have younger students invovled, helping to create robotic activities for students their own age.
In the summer of 2017, Vivek was invited to participate in the shooting of a new 10-episode NBC series called "Genius Junior" hosted by Neil Patrick Harris. This is a clip from the next to last episode that aired on Sunday night, May 13th. In the video you will also see, John Kuk (mentor for the Knight Rover project), Kevin Dalle (senior IT major at Illinois State), and Dr. David L. Anderson (director of The Mind Project).
