Callio provides a cloud‑hosted platform that lets robotics competition organizers define scoring rules, schedule matches, and monitor live telemetry from robot controllers via MQTT, ROS2, and other protocols. The web‑based challenge screen offers real‑time dashboards, role‑based access, and persistent result storage with export APIs for LMS and analytics. It integrates with existing hardware simulators and learning management systems through REST and WebSocket interfaces.

Problem
Organizers of robotics competitions and educational challenges often rely on ad‑hoc spreadsheets, manual timing systems, and disparate hardware interfaces, which leads to inconsistent rule enforcement, limited real‑time visibility, and high administrative overhead. These inefficiencies hinder participant engagement and make it difficult to scale events across multiple venues or remote teams.
Solution
Callio delivers a cloud‑hosted platform that centralizes the creation, execution, and monitoring of robot challenges through a dedicated web‑based challenge screen. Event administrators can define competition parameters, scoring rules, and safety constraints using a visual configuration UI, while the system automatically provisions the required runtime environment for each match. During execution, the platform ingests telemetry from robot controllers via standard protocols (e.g., MQTT, ROS2) and updates a live dashboard that displays scores, time remaining, and performance metrics to participants and judges. All results are persisted in a relational database with audit logging, enabling post‑event analytics, leaderboard generation, and data export for reporting or research purposes. The solution integrates with existing learning management systems and hardware simulators through RESTful APIs, allowing seamless embedding into curricula or virtual competition platforms.
Target Audience
Primary customers are robotics competition organizers, university engineering labs, and K‑12 STEM programs that need a scalable, standards‑based system to run and track robot challenges.
