CEENBo. T ™ Educational Robotics Platform Dr. Bing Chen Computer and Electronics Engineering October 27 th, 2008
Goals of CEENBo. T for ECE-type programs • Attract high school students in choosing to enter ECE as their field of university study • Encourage ECE students to buy into their programs with an educational robot that is utilized in multiple courses • Stimulate faculty in “freshening” ECE courses • CEENBo. T can serve as a portfolio of for ECE students and for out of class “fun” activities
Comparison of Tek. Bot and CEENBo. T Tek. Bot™ - Oregon State ECE CEENBo. T ™ - UNL CEEN
Tek. Bot™ - Oregon State ECE • • 5” by 7” footprint DC motors with plastic gear train and foam wheels Compact design Prototype board for use by college students at both Oregon State University and University of Nebraska (to 2007) CEENBo. T ™ - UNL CEEN • • 6” by 8” footprint High-quality stepper motors for precision control Full suspension for traversing uneven terrain Larger capacity, quick-change power supply Interchangeable rubber drive tires Large prototype board for projects and more reliable connectors Serial-to-peripheral interface (SPI) to allow communication between multiple multiprocessors Amenable to K-16 educational space to meet needs at multiple levels
CEEN experiences to date • CEEN faculty have bought into the educational robotics concept in a NSF CCLI phase 1 grant with the Tek. Bot • CEEN students: • are provided a robot in their very first freshman course (learning to solder, gaining familiarity with circuit elements and reading circuit diagrams) • can do individual study courses to extend their robot’s capabilities beyond their prescribed labs (e. g. robot arm, video camera) • have contributed to lab development along with their instructors • have designed the “CEENBo. T” with a quantum leap in added features “testosterone satisfaction”
CEENBo. T Features • Robust and scalable mobile robotic platform for ECE programs to take it in any direction desired • Base unit CEENBo. T can be viewed as a stable power supply on wheels which can utilize RC hobbyist parts • Open source architecture makes for a flexible platform • Optional GPI board provides for multiple languages for control and multiple audiences (K-12, 4 -H, after school)

CEENBo. T features: now and upcoming • All CEENBo. Ts now have UPC barcodes and serial numbers for tracking • Tested: video camera with wireless transmission to a laptop, robotic arm, four-wheel drive version, Zig. Bee controller • Under development: GPS module, Wi-Fi controller (802. 11 b), interface ports for multiple sensors • In addition to base kits with through hole circuit boards a surface mount version is under development

CEENBo. T: Plans for the near future • Manufacturing costs are dropping • $275 for summer 2008 NSF workshops for teachers • $175 for fall CEEN freshman students • will approach $100 (parts and labor) for the next order of 1 K CEENBo. Ts for spring 2009 • GPI board will be ready by summer 2009 • CEENBo. T, Inc. will be formed by summer 2009 to manufacture and distribute CEENBo. Ts
Next NSF proposal: CCLI phase 2 Due: January 12 th, 2009 • Collaborative proposal with selected ECE departments as partners • Observe and measure the effectiveness of the CEENBo. T at other ECE locations • Assessment tools (already developed under CCLI phase 1) will be applied to students and faculty at partnering schools • CEENBo. T jamboree for partnering schools held annually for most innovative application, best lesson modules for a course, challenge problem
Are you interested? CEEN would love to have you with us! • If you have an interest please let Bing Chen know as there are only a little more than 2 months to prepare the proposal • Forward a copy of your NSF-ready CV. If you are a Co. PI we will need a list of your current and pending grants through NSF • A letter of support stating your commitment to work with us
