– Anton Danielsson and Elias Löthman put more than 2000 hours into building a radio controlled version of Hägglunds' armored tracked vehicle CV90. From the beginning it was not meant that the project would become quite so ambitious.
– We wanted to build a tracked vehicle mostly for fun. When we contacted BAE Systems Hägglunds to get the drawings to their tracked vehicle CV90, it turned out that they could have use of a radio-controlled model to use in product demonstrations, says Anton Danielsson who reads the fifth and final year at the Master Programme in Industrial Design Engineering.
Demonstrates camouflage systems
– BAE Systems was very positive about the end result, and they have already started to look at work for our thesis. The radio-controlled tracked vehicle will for instance be used to demonstrate a camouflage system that involves installing heating plates that manipulates the heat signature of the vehicle. It is obviously much easier to bring our radio controlled model for fairs, compared with a full-sized tracked vehicle, says Elias Löthman who also read MSc in Industrial Design Engineering.
Electric motors provide good power
The 200 kg radio-controlled tracked vehicle is easy to drive and it is a powerful machine that easily can go over piles of rock and sand. Anton and Elias has certainly managed to emulate the 23-ton model.
– The chassis is built of 4 mm sheet steel TIG welded to a self-bearing body. It is powered by two 48V 5kW brushless electric motors through a chain-gearbox. The courses in the field of mechanical engineering we read have given us a lot of skills that were necessary to complete the project. We got access to a workshop and equipment while the teachers in mechanical engineering has been a fantastic support, says Anton Danielsson.
More construction underway
Although the tracked vehicle is their most ambitious construction so far, Anton and Elias have also during the student years managed to build a compact snowmobile, a "lethal electric scooter" and a small wheel loader. And more things are on the way.
– In the workshop we have now started to build the world's smallest rally kart, a small Bobcat is underway and we have also contstructed the foundation for a new tracked vehicle, says Anton Danielsson.
