Technical Data of MART-i

This page summarizes the technical data of MART-i, the first instance of our modular airborne real-time testbed.

Flight performance

The purpose of our platform is not demonstrating superior air performance, but applying novel approaches for design, analysis and verification of embedded systems. Consequently, for safety reasons, the peak performance of the quadrocopter is artificially limited. This gives us more reaction time to counteract potential malfunctions, especially to avoid leaving approved airspace. So far, the proven maximum ratings are:

Airframe & Propulsion

The structural parts as well as motors and propellers are integrated in a modular way and can be exchanged to make a mission-specific tradeoff between payload and flight time. For example, the quadrocopter can be configured with a light-weight, low-power propulsion system allowing for a longer flight time, but with less payload.

Flight Control System

We use the proven and open source autopilot Ardupilot in its latest generation hardware, together with a customized firmware. It features a 6 DoF accelerometer/gyro, a Galileo/GLONASS/GPS positioning system, a compass, a high-performance barometer,  a sonar and a data link for live monitoring and control.
