Robotics is making a major impact on how we work, play, and learn. Al, automation, and robots are hot trending topics discussed in trade publications and online news feeds. According to IDC (International Data Corporation) the robotics industry and associated partners will reach $135.4 billion by 2019. IDC’s research also showed international robotics spending was $71 billion in 2015 and is expected to grow at rate of 17%.
The global educational robotics industry is forecasted to grow at a CAGR (Compound Annual Growth Rate) of 21% by 2020, according to Technavio’s market research. Educators are incorporating robotics into their STEM and CTE (Career-Technical Education) curriculum to train the new skilled workforce of engineers and technicians. This skilled workforce will be responsible for designing and maintaining advanced robotic systems. Key vendors in the educational robotics market are exploring mobile technologies to enable classrooms to experience a rich learning environment. Some of these key vendors include but not limited to are:
- Modular Robotics
- Tetrix Robotics
Another educational robotics vendor that provides a low cost kit for K-12 classrooms, colleges, and universities, and individuals is Parallax Inc. Parallax provides a mobile-based robotics platform called the BOE (Board of Education) bot that allows a variety of coding and electronics technology skills to be acquire with this kit. The BOE bot shield provides the electrical interface between the mobile base servo motors, breadboard sensors, and electronics to an Arduino microcontroller development platform.

The Parallax BOE bot Architecture
Developing mobile robotic applications using the Parallax BOE bot is based on the Arduino shield design. A small pcb (printed circuit board), dual inline header connectors, a 5V DC regulator, and mini solderless breadboard allows a variety of electronic circuits and sensors to be attached to the Arduino shield. There are two additional connectors for attaching continuous rotation servo motors on the pcb, as well. The flexibility of the shield allows for exploring robotics concepts such as navigation using tactile switches or “whiskers” or alarm status indication with a piezo-buzzer for alerting completion of a robot task. IR (infrared) detectors allow ordinary TV remotes to operate the BOE bot. This IR control feature can be accomplish using the prototyping shield, as well. With Arduino platforms as the YUN and 101, WiFi and BLE (Bluetooth Low Energy) applications can easily be prototyped using this flexible interfacing architecture design.
