9. We created an all-terrain autonomous robot with
the aim to explore the planet Mars. it's mission is
to dig big wholes in Mars surface when needed,
without any external digging system.
The Robot “Digger “ is equipped with 6 wheels
that makes it roll smoothly and even in hard
conditions; each wheel is driven by it’s own DC
engin.

10. *When it comes to the electronic part, we suggest to
use The microcontroller, which drives the H bridges
that can move the 6 wheels forwards and backwards
independently such as (PIC32MZ1024ECG064) , and
adopt the PCB with the conditions in Mars; such as
radiations resistance.

11. •We thaught about equiping the robot with a sensor
that can detect certain frequency in the bandwidth.
for example :
the bandwidth varies from 100Hz to 1000 Hz: if we divide it into
ranges we can have the analysis below :
[100Hz,200Hz] : in this range we will have an indicator like a green
lighted led. That means you ‘ astronomer’ you can here the sound
easily and do not influence your ears sensitivity) .
[600,1000]: a red led lights. That means you cannot be able to hear
anything and the hard sound will influence your ears sensitivity
thus to say you astronomer aren’t the ideal one for this mission.

14. The drive shaft can rotate in a range of 60° around the
main axe to allow the robot to avoid obstacals.

15. The drill is made from titanium to surve as an
anchor to make the robot stable while spining.

16. The robot is able to spin aroud itself by inverting the
rotation of wheels. As the shield are deployed. The
robot is able to move sand.

17. We’ve worked on a mecanical idea that will improve and facilitate the mouvments of the
Robot on Mars that we’ve developped with the software « Solidwarks ». Here is it’s 3D
design.
