R2 Programmable Robot Set for S.T.E.M. Elementary Education

  Educational Laboratories, STEM & Robotics

Arduino Block programming Physical Computing Primary Education Robotics S.T.E.M. SMART:Blox

Overview

The R2/KC6+ Learning and Coding Robot is a programmable educational robot car designed with an easy-to-use and flexible open-source Arduino platform. The robot’s microcontroller includes 4 analog and 4 digital inputs/outputs and features an RJ11 type input for easy and direct connection of additional sensors, ensuring seamless interoperability between them.

The R2/KC6+ Learning and Coding Robot can be programmed with either the R2.bit application available for tablets or the ARD:icon software available for pc and laptop.

Control Features through the R2.bit App

  • Reaction to sound, light, and touch stimuli
  • Obstacle avoidance through an Ultrasonic sensor
  • Line guidance
  • Programming the movement of the wheels in different directions
  • Production of visual and audio indications

By using the ARD:icon software and the ready-made activities provided, users can delve deeper into the robot’s various functions and take the first steps in programming and computational thinking through a tile-based language.

This set is selected as suitable educational material for primary education in STEM-Robotics in Primary School (grades 1-4) by the Hellenic Ministry of Education.

Safety

The entire R2 Robotic Set is stored in a durable plastic case along with all its supporting hardware for added safety.

Educational Material

The ARD:icon EB teaching subsystem incorporates the curriculum and enables students to perform activities independently through software instructions (C.A.I.) outside the teaching period (self-paced training) and within the teaching period under teacher supervision. The EB software subsystem of ARD:icon integrates all teaching modules, including:

  • Student Training: Utilizes the set of materials used by the student.
  • Curriculum and Theory: Provides demonstration aids for the teacher, fully utilizing the set in the educational process.

The application is written in HTML5, downloadable from a web hub. It is also available in SCORM 2004 (Sharable Content Object Reference Model) format and structured as an e-course that can be uploaded to the Moodle open-source e-learning platform. All course plans offer the contents (theory and practical activity) in e-book/e-course format.

Educational Material Content

The software/eBook offers a step-by-step sequence of instructions for each activity through the C.A.I. (Computer Assisted Instructions) software. Each activity in e-book format contains:

  • Relevant theoretical references
  • The aim of the activity
  • All relevant diagrams and connections
  • The building of a program in block language
  • The corresponding code
  • Practical exercises in 30-minute videos

The material comes with supporting educational tools for developing different types of mechanisms with an emphasis on STEM Engineering, using a microphone, servo motor, and signaling (sound and light). It provides a variety of activities for each class of elementary school:

The ARD:icon CS Subsystem

The educational material is supported by the ARD:icon CS subsystem, based on the ACADEMUS CRS© software. This tool is a simple, flexible, and easy-to-use teaching aid, in the Greek language, supplementing the C.A.I. environment offered at ARD:icon EB for all Primary and Secondary Education teachers. For a detailed description of all the system’s features, visit Academus CRS.
