How Torotic Built a Modular Robot for Kids—Fast and On Budget

three Torotic robots assembled

Torotic set out to solve a common problem in children’s coding education: students often write code but never see it work in the real world. The goal was to create a robot that was affordable, modular, and ready-to-use—giving kids the ability to upload code and immediately see it come to life.

PrototyperLab supported Torotic through the whole cycle: concept development, engineering, prototyping, and production. The result is a versatile learning robot built for hands-on education.

Key Requirements

To meet the goals of real-world coding education for kids, Torotic needed specific technical and production capabilities from day one.

  • Affordable, low-volume production for early testing
  • Pre-assembled robot core with plug-and-play modules
  • Real-world execution of code written in a block-based editor
  • Modular platform for gradual expansion

Features

These are the core components and systems that made the Torotic robot functional, expandable, and ready for real-time student interaction.

  • CenterCube Core Unit: Fully assembled hub for modular attachment
  • Custom Blockly-Based Interface: Visual programming tool adapted for hardware integration
  • Input Sensors: Sound sensor, distance sensor, button, real-time clock, IR receiver
  • Output Components: LED screen, multicolor LED, speaker

Development Process

Torotic completed the project in 690 engineering hours using PrototyperLab’s structured prototyping workflow. Each step focused on building a usable, testable product without unnecessary delays or overspending.

The team handled all development phases under one roof:

  • Hardware System Design: Planned and built the core structure, motion system, and modular shell to support quick assembly and expansion.
  • Circuit Development: Designed, tested, and integrated electronics to support plug-and-play sensors and output components.
  • Firmware Programming: Created the internal logic to control robot functions and enable communication between hardware modules.
  • 3D-Printed Enclosures: Produced robust, lightweight shells for the core unit and add-ons to keep costs low and turnaround fast.
  • Custom Blockly Integration: Adapted the visual programming tool for direct USB upload and real-time hardware interaction.
  • STEM Curriculum Creation: Developed a 150-hour instructional program, including lectures, exercises, and hands-on activities to support educational use.

Prototyping and Development

Instead of navigating multiple vendors, slow timelines, and hidden costs, Torotic worked under one roof with a dedicated engineering team. 

Every phase was handled quickly and transparently, from initial concept sketches to electronics design, 3D-printed enclosures, and custom code integrations.

Challenges Addressed

Throughout development, several technical and usability issues were identified and resolved to make the product practical and classroom-ready.

  • Assembly Complexity: Reduced with CenterCube’s pre-built core
  • Code-to-Real Gap: Solved by real-time USB upload and hardware response
  • High Cost of Flexibility: Avoided with modular design
  • Limited Engagement: Overcome by bundling sensors and outputs for creative projects

Outcome

The robot is now in use for STEM education in classrooms and at home. With a 150-hour curriculum and support for dozens of projects, the product delivers real-world coding experience at an accessible price.
