Pro Contest: PCPA 9000

This contest has ended. Thank you for all your great entries. Please check out the winners and highlighted entries below!

Welcome to the first official Principia Pro Building Contest!

Attention! We've just received an urgent message from PASA (Principia Aeronautics and Space Administration), they need our help with exploring mars. Their rovers are too limited, they need something better and more versatile, specifically they need the PCPA 9000, a walking exploration robot. We've lost our design documents and need your help with coming up with a new design for the robot.

PCPA 9000 Technical Requirements

You have four weeks to build, submit your entry before Monday February 3rd.

The winner gets a Black Diamond Trophy worth 12 points.

The first runner-up gets a gold trophy worth 5 points

The second runner-up gets 2 silver trophies worth a total of 2 points.

Tips and Hints

The gravity on Mars is 38% of the gravity on Earth. Principia gravity is -20 y, Principia mars gravity would be -7.6.

Is there anything for the robot to find on Mars?

Feel free to loosely define "walking".

Pro Contest judging & general rules

Pro Contest entries are judged very hard, we will provide feedback to each valid entry and allow you to make any improvements at any time before the contest ends. Below is a list of things that can get your level disqualified:

How to Submit an Entry

After you have uploaded your level, browse to its level page, choose the correct contest and click "Enter level into contest".

  • JOELwindows7: Congrats again TechZ. But @sdac: you say that is black diamond. But really, it is black crown!
  • zardOz2: @The_Blacksmith_: see sdac's comment below
  • The_Blacksmith_: Who's the second runner up?
  • zardOz2: @sdac: np sdac, You still get 122 more passes;) I could have done something more, I decided to just release a bunch of assemblies like shared fuel tank for people to use.(or not use lol)
  • Golden: About abrackers
  • Golden: Oh wait nvm
  • Golden: Also abrackers dont have gold crown
  • Golden: Oh ok i just read description but why Techz dont have black diamond crown
  • sdac: Due to the amount of time we've allocated for the 1.4 update we didn't have enough time to give this contest as much attention as it deserved, we're hoping to be more involved in the next Pro contest. Thanks everyone for your amazing entries and comments. We decided not to pick a second runner-up as most of the entries lacked fine-tuning in terms of camera/rc automation, simplicity or did not respect the requirements. During the next pro contest we will try to be more involved to give everyone as much feedback as necessary. Thanks! Also, zardOz, sorry we couldn't get you the artifical gravity object out before the contest ended. You will have it in 1.4
  • zardOz2: Theyre not listed in order G
  • Golden: Wait wheres second runner-up and crowns.....
  • Golden: Damn my level is almost last and useless :((((
  • Golden: Congratulations Techz and abrackers!!!
  • Golden: Because my favorite color gold
    Thats why my username is golden
    Thanks pajlada for info
  • Golden: Man i wish i really want a golden trophy :(
  • pajlada: There has been a slight delay, we will post an update some time tomorrow.
    We are in the process of typing out feedback to a lot of entries. The feedback will be late, for which we apologize, but we hope it will be appreciated anyway.
    Thank you for all your great entries and patience!
  • Golden: Still, today is February 4..
  • RasmusOlle: My timezone is same as S&P
    Also time: 13:12 3 Feb
  • Golden: Why this contest still not finish today is February 3 2014
    20:00 GMT
  • abrackers2: @sdac: you said you would provide feedback to all valid entries. Is there anything I have missed given u appear to have provided feedback to some other levels published later than mine?
  • TechMan101: Hi
  • abrackers2: I'll be putting my level up in a couple of days. Need to be careful of object numbers though. Already got 5000 objects
  • zardOz2: Or just change the game settings to -7.6y.
  • zardOz2: Mars gravity = .38 signal to fallback input at ground level.
  • yong: well hey, how to set up the gravity?
  • zardOz2: Im not that far along in my build.... but I probably wont do parachutes. I just hate the magic stabilizer... its tough to change things that already are in so many builds,.
  • abrackers2: @zardOz: by any chance r u trying to build a parachute using stabilisers?
  • zardOz2: Also I forgot a raw "state" in0, so it can be disabled and modified
  • zardOz2: Another request for stabilizer "improvements" currently it is resisting all the time, ro help with the realism I think it should be linear only, with a weight shift and resistance slider, when the weight hits the far end it stops helping, this will help with wobble but not create the unrealistic slow movements. Can add more than one at differrent orientations for angular dampen
  • Golden: @zardOz: hmm you should add that to tutorial
  • zardOz2: @golden: aye or condenser, wrap condenser etc. Something which stores data or relays data to home
  • Golden: @zardOz: you mean memory module
  • pajlada: @woodnut: Braking is fine, highly encouraged in fact. You wouldn't want your expensive prototype destroyed!
  • Golden: I got satellite dish
  • zardOz2: @Rubicon: better make sure at least one 1.0 is sent via transmitter to the sattelite receiver memory device, after landing
  • zardOz2: I think as long as there is ANY type of braking you should be good, just have to have something...preferrably not permanent on rocckets, for realism.
  • woodnut2: I've got my PCPA started . About the landing , can speed be reduced before the landing ? (rockets) . Or must it free fall @ - 7.6 gravity until landing ?
  • Golden: I got something special for THAT contest ;)
  • abrackers2: I assume it is dropped/fired from a satellite which it then sends data back to
  • Rubicon2: What do you mean by "sending data back to satellite" ?
  • abrackers2: Also the sensitivity of object finder for distance Is way too high. 0.05 is the only noticable one and is still too high
  • abdussamad: how to update principia from this website?
  • abrackers2: 2 things. Firstly, can we have a rubber cylinder added, with the same size options as the wooden cylinder, or add a wheel size which is the same size. Secondly the if devices under signal-misc work the opposite way round to their description.
  • The_Blacksmith_: Even though I'm not a pro, I'm giving it a shot!
  • RasmusOlle: @zardOz: i create a level soon!
  • ElementalGenius98: Ive got so many ideas but i must improve myself until i can build that beutiful machine im imagine >.< maybe i get the hang of all those signaling stuff until contest is over ^^
  • zardOz2: @RasmusOlle: ? Do tell
  • RasmusOlle: @zardOz: you can do it with sensors
  • abrackers2: @pajlada: Thanks. Also, given this is a pro contest would it be possible for us to have a Mars background in a future update?
  • pajlada: Monday Februrary 3rd
  • abrackers2: Also when does the competition close?
  • abrackers2: I'll see what I can come up with. I'm in
  • z0a8i: Iam completley in ,just a matter of my time i am busy with an other priority :/ but i will do what i can do at the time,like the idea
  • Golden: Oh no rover allowed
  • Golden: But I need lua help
  • Golden: I make mar rover ;)
  • sdac: @mbrine: anything wrong? you don't like this contest?
  • mbrine: ...
  • sdac: IMPORTANT: If a bug, nuisance or missing feature is preventing you from building exactly what you want, report it immediately and we will look into it. Pro Contest entries are very high priority, we don't want you to be limited by Principia.
  • sdac: @TechZ: It must move using a method better than just having wheels, feel free to define "walking" very loosely
  • sdac: @jammer312: yes and yes
  • TechZ2124: Just a question : must the robot be a walking robot or can it be a rover ?
  • jammer312: Can it be automated(you can control AI states), can it use lua script?
  • TechZ2124: I think I will build one. I have not so much time to spend now but I will try to build it.
  • sdac: Good luck everyone, please leave a small message here (like zardOz did) if you plan on participating in the contest, it will help us get a general idea of how popular these Pro Contests are at this very early stage of Principia's life.
  • zardOz2: Awesome! If you'll notice my Planet Principia level, I think I can get a whole solar system with indenpendent gravity planets, but cant do it for two objects rover+satellite..
  • sdac: Sure, we'll throw in a local gravity object. You'll have to wait a week or two though because the next update has some pretty big changes that can't be pushed out right now.
  • zardOz2: Any new parts planned to be released before the 3rd?;) cough like some kind of local gravity object?
  • zardOz2: Im in!
