THE DRONES
INKY, BLINKY, PINKY & CLYDE
2019
This year we for the first time had a drone swarm! We built four drones and named them after Pacman.
​
More techincal details is on its way! Stay tuned!
MIST
2018
This years drone is a new and improved version of last year´s drone. It got more computing power and sensors than the previous one. The structure of the drone is made out of carbon fibre and 3d printed parts. This makes it modular, which allows easy testing of multiple technologies.
​
The drone feature two Nvidia TX2s, which run the operating system based on ROS. The landing gear has multiple sensors for detection of height, landing and physical contact with ground robots. The new and lighter cameras is isolated from the frame to minimize vibrations.
VALKYRIE
2017
Our third quadcopter was designed as a physically robust platform for testing new control software. The small size and low weight means that we can test new control strategies, including landing on ground robots, with less risk of damage to equipment.
​
It has a Pixhawk flight controller and an Intel NUC onboard computer running Ubuntu Server with ROS. The custom made frame made of carbon fiber and 3D-printed parts allows compact placement of the hardware and even weight distribution, and well balanced motors from T-Motor minimize vibrations and yields high efficiency.
DRONE 2.0
2016
Our second aerial robot is custom designed using carbon fiber and 3D-printed parts. It was build for the 2016 IARC and designed with Mission 7 in mind, and it is able to carry all the equipment we need to herd the target robots across the green line.
​
The sensors it has for navigation, ground robot detection and collision avoidance is five cameras, one laser rangefinder, one 2D laser scanner, and an inertial measurement unit.
​
The data processing is done using an on-board Intel NUC, in addition to an external computer communicating using WiFi. The flight controller is a Pixhawk connected to the NUC.
​
Our software can recognize the lines and corners of the grid, detect target robots and decide when and how to interact with them.
