CanSat competition 2020/2021

CanSat cover was designed in Solid Edge 2020 to print it on a 3D printer. The box consists of a middle segment and two gears with internal toothing, fixed by a cover. The middle segment consists of two parts for easy access to the components inside. All folded elements have clearances (0.4- 0.8 mm) so we can easily put them together and the gears rotate without any problems.

​

The CanSat, both in flight and on the ground, will move horizontally, which will make it more stable while driving. The battery will be placed in the bottom of the box to move the weight as close to the ground as possible. At the beginning we wanted to use tracks, but we came to the conclusion that it is too complicated and heavy mechanism, so we gave it up in favour of the wheels.

​

The wheel retraction mechanism is based on five gears, transferring the rotations from the motor to two screws, and two blocks with wheels attached to them. There is a nut in each block.

The screws by its rotation lower the blocks with nuts and get the CanSat on its feet. Then the gears on the wheel axles are driven by an internal gear.
