Our CanRise system is an autonomous probe fitting in a 33cl can.
The project consists in designing an operational apparatus that meets the CanSat contest standards, in which we are going to participate. The competition is held in a military ground in Biscarosse on August 2013, and is organized by CNES and Planètes Sciences. Our probe will be launched between 100 and 150m in height, using a balloon provided on site. It will fall at a 10 km/h speed thanks to a parachute we implemented. To achieve the different mandatory missions of the contest, we need to send the instantaneous altitude and temperature measures at a maximum period of 5 seconds, to a computer station where the team will monitor the outcomes. Moreover we have to target a point of impact on the ground defined by its GPS coordinates (given by the organizers). Two servomotors are used to act on the parachute and guide the probe into achieving that purpose. Finally, about 10m above the ground, curved metal pieces around the can will be deployed to ensure a safer landing and a better final posture, defining our free mission. A small antenna will be deployed as well to approximate real space expeditions.
The probe needs to still be operational at least 2 hours after its first use. After performing, a presentation in front of the jury will be held by each team to present the obtained results and provide an explanation of what may have gone wrong.
