deehtha Posted December 1, 2014 Posted December 1, 2014 I hope this isn't too late, as I am in the Eastern Time Zone, and there was no mention about what time zone the contest uses for ending. For this contest I chose to use sets 8047 and 8067. I don't own either set, so I got all the pieces that I had for both sets. I made a Mars rover, not modeled after any particular one. This model features full pendular suspension, moveable satelite dish, moveable tool arm, and a panoramic camera controlled by black gear in back. Profile picture with tool arm folded up and satelite dish pointed down. Picture from the top And my leftover pieces Quote
Jeroen Ottens Posted December 1, 2014 Posted December 1, 2014 Nifty little rover. I like it. How do you keep the upperbody horizontal? It looks like you only have a single axis to connect the wheels to, so what is preventing the body from tipping over? BTW you were on time... just... Quote
Zerobricks Posted December 1, 2014 Posted December 1, 2014 What a lovely rover. Too bad it doesnt fold. Quote
deehtha Posted December 1, 2014 Author Posted December 1, 2014 I used 3 12 tooth bevel gears to keep it up right. It acts like a differential, with the body of the rover as the differential housing. From what I remember reading a long time ago, this is how the real rovers do it. Unfortunately, the gears allow a lot of play, the body can tip forward by almost a stud at the ends. I tried to make it fold up, but I figure the tool arm folding would be best. Quote
Jeroen Ottens Posted December 1, 2014 Posted December 1, 2014 That is really cool +1 for ingenious mechanism Quote
