Ant Weight Circuit Help

Congratulations! Now you just need a shell for all of that to go in!

Cheers Guys yeah I’ll get cracking on that this week! Got a load of HDPE to cut! :/ no doubt I’ll have an fail video for you guys to see of me cutting my fingers off or worst.... Hahaha

So a bit of an update, had a new DasMikro through the post so I decided to wire that up instead of the old one with the broken pads on it. Ive got to this point...

However, I use to get a solid Red light on my lemon when I added my power. But now i get a slight flicker when I first push it in then nothing. Seen at about 58 seconds into that video.

At the start im just kinda showing that with the lemon not plugged in and the power supply plugged in first it does move the motors and they seem to be okay? So Im just wondering what im doing wrong? Have I messed up with the power supply wires? or the JR plugs? Or Something else? I think im getting closer to having something Ant Like anyway

I would advise against plugging things in while your system is energised. Your dasmikro seems correctly connected.

As to no led illuminated on your lemon , try rebinding it and see if it works. If you have a spare servo you could plug that in with just a battery and see if.

[Bad Wolf]

Okay I’ll give that a go! Was going to also ask do you need the bind plug that came with the lemon or will any do?

Bad Wolf

[Scottie]

Any will do. It's just there to short the bind pin to ground and put the receiver into bind state

So sorted a few things out and got to this stage

its going back when I want to go forward, what’s the quickest fix there? Do I swap wires around ? Also the back wheels are going a lot faster than the front, they are the bigger size wheel does that make any difference? :/ the front ones are turning but its going a lot slower than the back two! Any ideas?

Yeah, swapping the wires around at the motor end is the simplest way to resolve the back and forwards issue. The bigger wheel size will be impacting here. As for the motors turning at different speeds... I guess they are all the same gearbox ratio motors (so 30:1 or something like that)?

[Scottie]

Good job so far bro! The quickest way to make it go forward is to change it in the remote settings. Go to mixer. Find the channel used to go forward and select it. Go to src (the thing used to select which knob does what) and press enter on it. It should have an ! (Example !AIL) Next to it to show that it is inverted. The graph on the screen will also be inverted.

And do you mean that motors spin faster or do you mean that they cover more distance? You should expect the latter as their circumference is larger Hense they will cover more ground.

My lack of experience with a Devo 7e. :P I really should get one.

[Scottie]

Sorry Ocracoke! I just posted that on my phone and didn't realize you already posted. I wasn't trying to be mean or anything. I can appreciate that i sounded that way.

[Ocracoke]

I didn't take it to be mean at all, don't worry! I had completely forgotten that it was a Devo 7e being used here (despite it being in the video... -1 to perception) so flipping the direction is a good shout.

Ive managed to sort that in the settings! Thanks for that! I have a servo working as well on there now, so I’m going to now swap the wheels for 4 bigger sized ones and see if that helps the bounce on it! Thanks guys! I’ve also glue gunned the wires in place so hopefully that stops the Pads snapping off again!

So I’ve swapped the wheels, but it’s made it even more bouncy!

the motors don’t seem to be moving at the same speed, not sure why that would be :/

So then I lifted the front and it runs lovely, but I don’t want a 2 wheeled bot

Options anyone? Have some pointless wheels at the front that have no motor? Change the front motors incase they are at a different ratio? Totally change my design to just have 2 and YOLO it up? Lol

It's a bit hacky, but could you not pair the faster motors with the smaller wheels? Obviously I've no idea if the ratios are even close, but I'm just kind of thinking out loud.
