Sorry for all the updates today, but here is a video of the weapons drive mechanism. I just added the beams to simulate the arms, they will be much beefier than that Also, The video quality does not seem good at all. I took the video on my iPhone 5s but it doesnt seem good, what do you guys think?

It looks really good, I must say the yellow and green combo looks good together like that You said about wanting to slow down your bot, I am going to guess that you mean the drive.... I might have a suggestion. I am going to send a you PM, if you are ok with what I send you, we can put it on here.

oh, sure you could control 2 functions with a worm gear, but I do not advice it. Using a worm gear is normally used to change direct of an axle and increase torque

You would need a gearbox to accomplish what you want. One motor and as many functions as you want. But, you would need another motor to change the gear since the contest is all remote control. Hope that helps.

now you have me confused, what do you mean

Ok good, I will not be needed them, at least for this build. Thanks BlakBird

UPDATE: I did some more building last night after I posted this topic. I mounted the tracks, powered them, and added some armor. I wish I took pictures during the build, but I did not sorry. The picture above is the front, but it does not really matter which way is front and which is considered the back. And here is a picture of the drive. Using Sariel's gear calculator I found that the gear ratio is 1:4.5 Things to come: Add 2 more battery boxes in the back Add Sbricks once they come in the mail Figure out where wires can go to get out of the way of the moving parts. Then figure out a strong spinner for the top. That will be last though. Hope you guys like the progress. Tell me, would you rather progress pictures more often or like one big post once a week?

A motor would get connected to the bottom axle. Then the motor would be connected to the receiver.

Thanks for answering all my questions, and I got all the answers I wanted to hear! Sounds like what I want to do will work. What's the difference between an Sbrick and Sbrick plus?

Do you mean connect the L motors to the switch and the switch to the S brick? With the switch in the always on position? Or do you mean switch connected to battery box and a motor connected to s brick to control switch?

battery box -> receiver (channel 1) -> blue -> drive red -> steering battery box -> receiver (channel 1) -> blue -> drive red-> This is what I was talking about. Having both receiver set to the same channel allows you to have more battery boxes and still only control with one remote. I hope that clears things up. The only down side to this is that you can not really use the other "red" port because that would only move when you are steering. As for the mA for battery boxes and motor, I am not sure and I do not want to tell you incorrect information

I was worried about the drive too, so I tested it last night. I loaded the bot up with all the battery boxes I had (10) and it drove around, it did not like turning, but it did it. Also, My bot will not weigh that much. I am hoping 4 battery boxes is enough.

I am calling them fails because they did not work for what I wanted. And yes all of the the fails in the TC11 folder are from this contest. I orginally was going to use the smoother wheels, but I would not get a good "mesh" between them. The wheels I am using not only mesh well but also give me a good output speed from the 8 L motors with a high amount of torque. 1. I tested all 8 on one battery box, didn't work. But 4 motors per battery box did work. 2. That's a good question. I am hoping balance is key and I won't have to mess with it too much

The link should work, it works for me when I am signed out of my bricksafe account. If you are still having trouble, please tell me My bot now has 10 L motors on it with 2 battery boxes. I am hoping to still add 2 more battery boxes, for more power divided and weight. Are 8 motors too many?

Hey guys, I have 2 Sbricks coming in the mail and they should be here some time this week. I have tried learning about the Sbrick and I can not seem to find the answers I am looking for. I have a couple quick questions; Using my phone as the controller, can I use both Sbricks at once? For a total of 8 channels running on my phone How many motors can I put on each channel? If I can only have lets say 2 motors per channel, can I control multiple channels with the same slider on my phone? Thanks in advance.

Hey guys, I am finally reporting some progress on my TC11 bot build. I have been following the contest very closely since it was announced. I started building the day it started and I finally have a solid start to a bot. I have rebuild and taken apart 5 bots so far, they all had something I did not like about them, a lot of the problems were probably because I was rushing into the build. Anyway, lets talk about the bot I wanted to get an idea of some bot ideas, so I decided to watch a bunch of YouTube videos of all kinds of battle bots, I found a lot of really cool and interesting concepts used. When I think of battle bot, I think of the bots that flip opponents and spinners. They both have their pros and cons, but I decided to go with a spinning bot and hopefully not one that self destructs. I decided to lightly base my bot off of the "Son of Whyachi" battle bot. I thought it looked interesting. after doing some research on the bot, I found out that the bot had an interesting drive system known as walking or shuffling, I might try this after the bot is done, but I do not want to run out of time trying to big this concept. For my bot I had some main focuses: durable effective weapon (focusing on one bigger one instead of multiple little ones) Easy to control (Sbrick coming in the mail, the IR receivers were not responsive enough) Compact As I said, I have built 5 other bots so far, I know what works for this and what does not. And like I said, I am not going for a prefect replica of the "son of whyachi" bot, just the concept of the top spinner. So here is a picture of what I have so far, it is not much as of right now, but I wanted to start a topic for motivation to keep building. The main weapon is powered by 8 L motors with the central gearing using tires. Originally I was using gears, but not having a clutch gear was not a good idea and adding the clutch gear did not give enough of a "punch", everything just kind of stopped. With using tires, I am able to have that "punch". You might be saying 8 L motors might be overkill, sure it might be, but it works very effectively. For the drive on my bot, I am going to be using tracks. I was going to use wheels but I had some trouble using them on my other bots, so when I tried tracks, they seemed to work out a lot better. Also building the battery box inside of the tracks helps free up some space on my bot. Just to give you an idea of how compact what I have is, here is a picture. It is a 15 x 15 square. I had the tracks on, and that will come out to a 30 x 30 square. So I have 15L to still mess around with. The link to my bricksafe is below if you want to check out my failed attempted bots. http://bricksafe.com/pages/Aminnich/tc11# As always, comments and questions are always welcomed. More progress to come soon, hopefully. Name to come later

How I divide my motors between battery boxes; 1 battery box has 1 receiver, but receivers are set to the same channel, have your drive motors on the same color and your servo on one of the receivers on the opposite color make sense?

Sometimes people use the m motor instead of a servo motor because they do not have a servo motor. If you can get a servo, go with that, it's a much better steering motor. 2 L motors should do what you want with one battery box. If you add another battery box for more power to divide amongst the motors, you are only adding weight. Stick to 2 L motors and 1 battery box. If for whatever reason the L motors are not enough, you can always hear them down for more torque. I hope that helps

How much weight can the bucket flip? It looks a bit flimsy

Well that's something I haven't seen before, technic being used to make bricks, very cool. I like the marble look to it as well, its something different. As for the bot aspect of things, using tracks is probably the better way to go, You still have a lot of room inside for a main weapon function too. You could move the L motors closer to the side direct to the drive sprocket that way you don't have the L motor in the way. Just my advice. Overall nice body for your bot, I look forward to progress!

Here I am thinking you had to take apart the old one to build the new one..... what was I thinking

Sorry about that, I was replying on my phone and auto correct always likes to correct me, I did not mean boy, I meant BOT

Do you guys want me to get my engineering professor in on the discussion? you guys are really gettin deep into this contest, you only have to build a bot, not do calculation on the angular velocity and acceleration of the spinning object at t=5 secs (only my engineering friends will understand that one ) anyway, I have a question about SBricks in general; how many motors can I have on one channel? Lets say it's 4, can I have a total of 16 motors per SBrick than? Or would the 4 motors only be for one channel? Im debating on getting an SBrick or 2, because I can slowly speed up my motors instead of a sudden ON or OFF

Ok so with that being said, I would guess that not many bots are going to be 45L tall. So we can have our bot fold upward, right? Does the bot need to fold down remotely? or can it enter the "arena" with whatever it is already folded down? I hope that makes sense.

it can be done, but if the size constraint is increased, i am sure we will see much better bots.
