Scorpio rovers family
Rover kept its modularity and construction is made of aluminum and polyamide – light material but it has very good mechanical properties.
Driving module is inspired by 4-wheels system rocker-boogie, which has been adjusted to our needs.
For good traction wheels are made of military material – corduroy, which we filled in with granulated Styrofoam, what increased rover stability and amortization. It is our own solution, which works perfectly. It has four-wheel drive, and each wheel is powered by separated engine BLDC 240 W. Because of that we have enough power to be able to over come the most difficult and demanding field and obstacles like wholes and steep landscape.
At first glance construction wasn’t different from the previous Scorpio IV, but it was improved.
For easier mechanical arm maneuvering we added 6th degree of freedom – rotation on the base.
We also took care of power – we created Power Manager, which controlled battery level.
We projected new, more capacious can for electronics. We also designed and created new drill for science tasks. Everything was made keeping modularity.
It was presented at first edition of European Rover Challenge in 2014 and it was completely different from its predecessors.
Main assumption of the construction was its complete modularity. It helped in projecting and testing each of every element.
We replaced suspension modified version of rocker-boogie suspension, known from NASA rovers. Modifications was all about adjusting construction to higher speeds and applying only 4 wheels. New suspension worked similar to Curiosity system. It was able to work efficiently with higher speeds.
Scorpio III was expansion of previous construction and it took part in University Rover Challenge 2013. Rover was articulated and had 6-wheels propulsion.
It had multifunction manipulator with six degrees of freedom. Also it had vision and measure system.
In comparation to Scorpio II there almost were not any changes in drive system and frame. We focused on reducing mass of those elements. Suspension was regulated for better cooperation with rover, which was 5 kg lighter. We added completely new manipulator – more precise and lighter than the older verison.
Innovations in Scorpio II was all about completely new 6-wheels suspension.
It was presented at University Rover Challenge 2012.
Rover’s off-road possibilities was increased.
We focused on decreasing arm mass but with keeping its size. Center of gravity was also changed – it was decreased by lifting engines on the bottom of kinematic chine, what influenced on stability of vehicle and arm lifting capacity.
Scorpio I is our first construction, created in 2011, which competed with rovers from all over the world at URC 2011.
It was remotely controlled rover with multifunction manipulator with vision system and system of remote measures.
Huge success was taking 4th place at competition in Hanksvill in the United States of America.
Despite of being its first time in competition, rover succeed such a high position.
This achievement was appreciated by the Polish Prime Minister, Donald Tusk. He even invited our association for a meeting.
