Root Robot Teaches Children? Harvard’s Bot Explained
Yes, Harvard researchers developed Root, a coding robot designed to teach children programming from ages 4 to 99. Root uses a visual, block-based coding language and can draw, erase, and navigate magnetic surfaces, making it a hands-on tool for learning logic and coding concepts.
What Is the Root Robot?
Root is a small, hexagonal robot created by a team at the Harvard Graduate School of Education and the Wyss Institute for Biologically Inspired Engineering. It was designed to be an accessible, engaging way for children (and adults) to learn programming. The robot is about the size of a hockey puck, with a clear top that shows its internal components. It can move, spin, light up, play sounds, and draw with a built-in marker. It is unique because it uses a whiteboard or any magnetic surface as its canvas, turning walls and floors into interactive learning spaces.
How Does Root Teach Coding?
Root uses a companion app called Root Coding, which offers three levels of programming complexity:
- Graphical (for ages 4-7): Basic commands are represented as colorful icons (move forward, turn, light up). Children drag and drop these icons to create sequences.
- Block-based (for ages 8-11): Uses Scratch-like blocks that combine commands, loops, and conditionals. This is the most common level used in classrooms.
- Text-based (for ages 12+): Uses a version of Python, allowing older students to write real code while still seeing the robot’s physical response.
The tactile nature of the robot helps bridge the gap between abstract code and physical action. When a child programs Root to draw a square, they immediately see the shape appear on the board, reinforcing the concept of sequence and repetition.
Why Did Harvard Create Root?
The project began in 2016 as a response to the growing need for computer science education in early childhood. The team, led by Dr. Marina Bers, wanted to create a tool that was both educational and playful, avoiding the screen-only approach common in many coding apps. Root was designed to be gender-neutral and culturally inclusive, with a simple, friendly design that appeals to a wide age range. The goal was to make coding as fundamental as reading and writing, giving children the ability to create with technology rather than just consume it.
How to Choose a Root Robot
If you are considering purchasing a Root robot, here are a few factors to keep in mind:
- Age and skill level: Root is suitable for ages 4 and up, but younger children may need adult help. The three coding levels make it a long-term investment that grows with the child.
- Surface requirements: Root works best on whiteboards or magnetic surfaces. It can also be used on a tabletop, but the drawing feature requires a vertical or horizontal magnetic surface.
- Compatibility: The Root app is available for iOS, Android, and Windows devices. Ensure your device is compatible before buying.
- Accessories: The robot comes with a charging cable and a dry-erase marker. Replacement markers and additional accessories (like a carrying case) are available separately.
Common Problems and Solutions
Like any educational device, Root can have issues. Here are a few common ones and how to address them:
- Robot not connecting to the app: Make sure Bluetooth is enabled on your device and that the robot is charged. Try restarting the app or the robot.
- Marker not drawing: The marker may be dry or not inserted fully. Use the included dry-erase markers and press them firmly into the slot.
- Robot moving slowly or erratically: Check for dirt or debris on the wheels and clean them with a soft cloth. Also, make sure the surface is clean and not too glossy.
- App crashes or freezes: Update the app to the latest version and ensure your device’s operating system is supported.
Root vs. Other Coding Robots
Root is not the only coding robot on the market. Here’s how it compares to a few popular alternatives:
- Sphero BOLT: A spherical robot that uses a similar three-level coding system. BOLT is more durable for rough play and has a built-in compass and infrared sensors, but it does not draw on surfaces. Root is better for classroom whiteboard activities.
- LEGO Mindstorms: More advanced and expensive, Mindstorms is for older kids (10+) and focuses on building custom robots. Root is simpler and more accessible for younger children.
- Dash & Dot: These robots are also block-based and popular in schools, but they lack the text-based Python level that Root offers. Root’s ability to draw is a distinct advantage for art-and-coding integration.
Cost and Value
The Root robot is priced in the mid-range for educational robots, typically around $200 to $300 for the standard kit. This is comparable to Sphero BOLT but less than LEGO Mindstorms. The educational value is high because it covers a wide age range and includes a free app with hundreds of activities. Schools often buy multiple units, and there are classroom bundles with discounts. For families, the long lifespan (from preschool to high school) justifies the cost compared to toys that are outgrown quickly.
Safety and Durability
Root is designed with safety in mind. It is made of durable, non-toxic plastic with no sharp edges. The robot is safe for children as young as 4, but adult supervision is recommended for the youngest users to prevent choking on small parts (like the marker caps). The robot is not waterproof, so it should be kept away from liquids. The charging cable uses a standard USB connection and is safe for children to handle with supervision. Root is also designed to be drop-resistant, though it is not indestructible.
Frequently Asked Questions
Is Root robot still being sold?
Yes, Root is still available for purchase. It was originally produced by Harvard, but the rights were acquired by iRobot in 2019. iRobot continues to sell and support Root, and the app is regularly updated.
Can Root work without a whiteboard?
Yes, Root can move on any flat, smooth surface like a table or floor, but the drawing feature requires a magnetic whiteboard. If you don’t have a whiteboard, you can use a magnetic sheet or a metal surface with dry-erase markers.
Do I need to know coding to use Root?
No. The app is designed for beginners, and the graphical level requires no prior knowledge. The app also includes tutorials and sample projects that guide you step by step.
What age is Root appropriate for?
Root is marketed for ages 4 to 99. The graphical level is for young children (4-7), the block level for ages 8-11, and the text level for ages 12 and up. Adults can also enjoy learning Python with Root.
Can Root be used in a classroom?
Yes, Root is widely used in schools. There are classroom kits that include multiple robots, charging stations, and a curriculum guide. The app supports multiple robots per device, allowing for group activities.
What is the battery life of Root?
Root has a battery life of about 2 hours of continuous use, and it takes about 2 hours to fully charge. The robot can be used while charging, but it is recommended to charge it fully before class.
