designing mars lander

when we started using tinkercad for our rover design it was starting out a little hard but it did pretty well during it it got better and better for design purposes it took time to find of what to make but it got partly made then i got my test model. after test and thinking i got the next design it may not be fully finished but this is the design the most people would already know this but the wheels have a spring added into them those were the best tires i could find. the rings around it are bolted into the machine for pressure stabilization from leaving and or landing on a planet and or moons if i could make it the inside would be half of machinary and half storage for items i dont know what but some items that can be used for research. the red things with the carrot like things are originally arms for the rover so it can pick up materials and put them in the storage it not fully complete but it should be soon.
