hi i cant upload the with the ide....
can you help me please...

Absolutely, although I’m not sure I understand what the issue your having is, is it that you can’t upload the sketch to the Arduino board?

Followed all of your instructions and I have it completely built and the Mrk2 code installed, but all he is doing is turning right. I installed an ultrasonic sensor, I don't have a joystick or anything else. I was wondering if I have to delete the joystick part of code for him to work properly or what I might be doing wrong.. Thanks

If I’m thinking about it correctly, there are a couple things that may act as potential solutions. Try moving the method that controls forward movement to the main part of the loop and remove the code that checks for joystick movement. If at that point, it still continues to turn without doing anything else, try and make sure you have the sensor connected up correctly (this has caused me many hours of trouble shooting). If then the issue of turning continues and you aren’t worried about object collision avoidance you could remove the code that makes it turn when it sees an object, or even change it from running the turn method to instead running the walk forward method to see if you have everything hooked up correctly. I do hope this convoluted explanation is helpful. Please feel free, if you have more questions, to ask.

I am in the middle of printing all of the parts and have all the components on the way. I there a chance we can get the files in STEP format for Fusion 360. I would love to contribute but I don't want to have to rebuild all the work you have done from scratch. TIA

If I had those I would upload them but I’m not actually the original creator of the parts. I simply assembled it and made some code that got it walking which is why mine is just a remix. I would recommend reaching out to the original creator. If there is anything else I can do for you please don’t hesitate to ask!

Hey thanks for posting this! Could you provide the instructions on how to wire up the rest of the build? The battery picture on the original mix makes accuracy a bit harder than I would like for a first go. Again thanks for this remix, very helpful for the servo pinout!

Absolutely! I didn’t know if people would be interested in something like that but I’ll get on it. It will take me about a week or so to get it to where it would need to be, but keep a look out as I’ll try to post it ASAP. Thanks for the suggestion!

Hey man, no worries thanks for the reply, just bought some battery holders I will tear apart for the battery holders for this. Lol. Couldn't find the guts only on Amazon. Free same day is awesome and dangerous. Thanks again.

My recommendation, check the original because those batteries work well, and then use some tin foil to make tabs you can solder wire on to. That way it works well with the case in the download.

Gotcha, using 18650 batteries, didn't think of tinfoil. Amazon will be here soon and I know they will work. But if that falls tinfoil for the win

do you have instructions to build it

Try the "Instruction Read Me" inside of the download but if you have additional questions feel free to ask.
