Have you tested how much weight the flipper can flip? I am not sure the servo will be enough

I will post pictures later, but the spinner fits perfectly within the 45L constraint. I am on my phone now, but once I am on my computer I can post some better pictures showing size Here is the picture: The blue measuring tool is 45L on the inside, where I am measuring from is the furthest distance from point to point. Exactly 45L long, could not have planned that better. Also, the bot is 22L tall with the tracks attached. I have added some reinforcements. It is almost done. I just have to make a good video now, it needs to be much better than the past couple videos I have posted. What have you guys thought of the past videos?

I just wanted to make sure with mine because it was so close, but Milan and I worked it out and mine is exactly 45L wide. Sorry for all the size debating and confusion

It is not the right place to ask, but I will give you a question answer Basically diagonal gives you 53L instead of 45L giving your bot a bigger advantage. You can fit more in the same space.

Was under the impression that it had to fit inside a 45Lx45L square in the starting position. Technically, my bot could be starting the match in the arena with the main weapon at a slight angle, but it fits. When I am building again later today, I will measure that green line you have marked and see what it is.

Thanks for all the name suggestions guys, I like them all. @Milan @Jim I need the the moderators of the contest to verify if my bot is too big. I am pretty sure it is, but I want to double check. I have included pictures of my bot inside a 45x45 square. The first picture is the bot inside the box from the top and the 4 others are pictures from the corners of the square. The bot's arms are right at the edge of the side beams, but they do not cross them, I made sure of it. If you have a problem with anything, please tell me sooner than later so I have enough time to change it. Thanks Once I get the go ahead or not, I will delete those pictures from the topic since they take up so much room. If you need to see them again, I will have them on my computer and can easily post them again.

Mine is the iconic black friction pin. I am not sure if any of you die hard technic fans have ever seen one, so I will post a picture.

Oh I like that....... Do you have that copy written? Haha

I am taki up the entire 45x45 area. And yes I knew that, I wasn't going to get all technical about the type of wood I was using haha I have not hit anything with it yet, the arms are not done yet. I still want to strengthen them Like I said, I am hoping to finish the bot this weekend, i have a lot of other stuff going on and the bot needs to get done now or it will never get done does anyone have a suggestion for the name?

Here is a quick video of what my bot looks like right now. More progress to come this weekend.

I remember when I was in highschool (not too long ago) and doing these kinds of projects. I loved doing the hands on activities that you were able to see how he concepts you were learning about could be used in the real world. I will say you came to the right place to ask for help, but I do not agree with you asking us for help. I wish you luck wit your project. btw, what Allanp posted would work perfectly.

The short answer, yes you can It would be better to have more than one battery box though

It works great and those are not empty battery boxes. Those have the good (heavy) duracell batteries, I still want to reinforce the arms those, don't want them to break off.

After building and rebuilding the main body of the bot multiple times and still not getting what I wanted it to be, I decided to build the weapon and see how that goes. This is my first attempt at it and I do not think it turned out too bad. Tell me what you think. PS, I would have uploaded a video too, but since I got the SBricks, I can not use my phone to shoot the video, I will have to figure something else out in the mean time

Simple, yet seems very effective. The drive is one step above as simple as it gets, yet it works perfectly. Your bot is not too slow and it not too fast to loose control. Everyone that is apart of this contest that owns a buggy motor have the right idea to use it for their main weapon. Using the power puller wheels is in my opinion the best choice for a bot that can be flipped over, not only is the diameter of the wheel the largest, but the side wall of the tire has a curve to it so it can be on its side and still roll over onto its wheels. Nice choice Overall, nice progress for only working on it for one day. What do you still plan to do to it? The battle bot Tombstone would be proud Btw, I hope you do not plan to keep the battery box on the top like that, it not keep you from being able to flip over and still function.

Honestly, I don't find any of the builds difficult, you just have to take your time and follow the instructions. The difficult part is modding the original builds and MOCs

I have all day tomorrow to build. I am hoping to get the drive system built better and start building the main weapon. If it works out like I want it to, I will be able to hit all the bots no problem

Alright, so I have changed a bunch of stuff. I am still not totally sure about the wheels, but I think I like this set up a lot better than the tracks. And it is much more compact. Here it is; The gearing for the drive -> 36t -> 16t -> 20t -> 8t -> worm gear So I speed up the L-motor and then using the worm gear, the speed decreases again. The bot is faster than when I was using the track, but it is not too fast. Tell me what you think :)

So as we get closer to the deadline of the contest we are starting to see so real progress on these bots and they are looking great. It looks to be instead of having pf and Sbrick categories, we should have had pf and buggy motor categories..... Harvester of Sorrow and hypnodisk (do not think is officially apart of contest) but use buggy motors for their main weapon and holy crap.... They are gonna destroy the competition. The buggy motor has a much higher speed output compared to any of the PF motors. And by the looks of hypnodisk, it packs a punch a mining truck. I know it is late in the contest, but I just wanted to share my opinions. Great job guys and good luck to everyone participating.

Well I better stop wasting my time building my bot, because yours looks awesome. Nice job! It looks good and seems to perform good as well. Lets see the main weapon hit something!

I do not mean to sound rude, but focus on your bot and I will focus on mine. I can focus on whatever part of the bot I want. If I want it to be fast enough to just run away from the enemy bot, I would have done that. Instead I am concentrating on the weapon, which in my opinion is the most important part of this contest. As it has been discussed a number of times, these bots are not fighting either other. We are only to show case our bot and the voters are to vote for the bot they think would preform the best. If you are voting for the bot that can maneuver around the arena better, than that is fine, but I do not think that is right. Also, looking at the real bots on the TV show, SoW had its flaws, but so did most all of the other bots. During the TV episodes, each on had their own strengthens and weaknesses. I only said I was basing mine slightly off of SoW. Keep in mind, we are building these out of LEGO, not titanium steel alloy that is bullet proof with car batteries inside for a source of power. These bots are not going to be meant for the main arena.

It is very unbalanced in that video because I am just testing everything. The final bot will be balanced. As for speed, why does my bot need to be fast? Is it in the rules? it doesn't matter how fast your bot is, it is all about how effective your main weapon is. That is what I am focusing on. The problem I have with my drive system is not the speed, but the amount of space it takes up, so I might be changing it soon anyway.

I am not posting this to self promote, but to have you guys make sure what I did is a legal move. I did not want to post the same thing on 2 different topics. It is a way around the size constraint, but still staying inside the 45x45x45 box

Update for today is interesting, I was working on how to strengthen the "clutch", instead I decided to test it with a battery box. In the video I test 2 different things, the battery box is the second of the 2 and the less interesting one. I think I am satisfied with the result as it is now. It knocked over a full battery box no problem and kept spinning like nothing was there. In the video I use 2 battery boxes, again no problem. Now for the interesting idea. Looking at my bot, I realized I was getting very close to the size restriction, not good. I had an idea to fold up the arms of the bot and use no motors or actuators or anything. Instead the arms would fold done strictly from the centripetal force of the spinning motion. I am not sure how lite the arms would have to be for this to work, but I still wanted to try it out. Here is a short video of what I have. I am still learning video editting, but I think I am getting better, I hope..... As always, comments and questions encouraged.

It is hear to tell how much force I am applying to stop the arm slipping around. It is not a lot, but it is more than I expected. I am not done reinforcing the "clutch" so many doing that will keep the wheels closer together and make it a stronger "clutch". If that does not work, I will go there my wheels and find a tighter fit. At the base of all my arms, I plan to have a battery box or 2, so imagine at the speed it was moving, having a battery box hit you in the face. Have a nice day
