Excessive Robot Tipping

Hey guys! I don’t have anyone to collaborate with so I was hoping I could get some tips online. My robot is not very balanced, it is always tipping from one side to the other. I wanted to know the best way to go about the problem, I don’t want to take apart my robot when I am unsure how effective changes will be. I am debating between bringing the front wheels farther forward to prevent forward tipping and maybe an anti tip in the back(which I don’t know how to build) for back tipping. Also any veteran tips about making a robot with a strong center of gravity would be greatly appreciated!

I would say to move your center of gravity down you should remount the brain so that it is lower and that will reduce a lot of tipping I am pretty sure.


that’s what I was going to say lol. but you should try making your base heavier than the top or bring the front wheels forward

okay yeah I will definitely find a way to do that. I assume having it in the bottom center of the robot would be the best spot?

First of all, I see that your robot most likely fits very well within size constraints at the base, so my first suggestion would be to move your front wheels forward up if possible to make your robot more spread out. On another note, if you notice, you also have a lot of space in the back so maybe extending your drive base back enough so that you can move the back wheels further can work too. It might also give you a new mounting place for your battery and brain


possible to do a short video to show how the robot is actually behaving?
Because it is important to solve the issue at the root, i.e. need to see exactly what is causing the robot to tip, and when it tipped, and how, etc.

of course, in general, lowering the CG will help. but some times it could be due to other reasons as well.


whatever works for you. i would put it somewhere accessible and lower to the ground

I would agree with this, This might not be a simple fix, so It would be nice to see what was going on in motion


I appreciate the help man! I am confused though by what you mean about space in the back. The back wheel is at the very edge of my limit so I can’t see how I could change that at all. Also there is a lot of empty space but that is for the balls to pass through

yes I have a video but it isn’t compatible with vex forum. best way to upload it?

If you don’t have space you can make your base bigger and have your intakes flip out. That if one option.

So the robot seems to fit well within 18 inches horizontally, so what I what I was basically suggesting was making the drive base longer. Rather than using a 25 long channel on the sides, maybe use something longer to compensate for tipping a little bit. It’ll be close to size constraints but if you run out of space you might have to do deployables on the intakes or something. That way you can make the weight distribution a little better.

And can you tell us the dimension of your robot. That would also help on giving us an idea of how much room you have to work with

Hey guys, heres a link to the robot

Well what can help fix this issue easily is by moving the brain and battery to the back of the robot and as low as possible

Instead of making ur chassis longer, I would suggest making antitips. Their less weight and you won’t have to take apart your robot. Also, make it so that you robot decelerates when the joysticks go to zero. Though it’s purpose isn’t this exactly, slew rate is a good way to accomplish that effect


Horizontal its 18inch, vertical its over 18 inch because of the hood (Im working on a way to make it retract). In terms of depth its about 16

I see a lot of teams do this. Doesn’t this make the robot tip easier in the back though?

What an anti tip?

i think he meant putting the brain lower
