New Quad Project... INPUT VERY WELCOME!

Ha, and Kurt, I know you’re the data/programming expert. Please help.

I don’t know for the .rar, but .zip normaly work i did post in the past.

I guess i will look elsewhere for a printer project… :frowning:

Any updates on your quad… Or printer.? :wink:

Sorry Guys!

I’ve got the files for the 3d printer. Sorry for making you wait so long Dialfonzo, I know you were looking forward to them. I’ll email them to you straight away. If anyone else would like them, just send me a PM with your email.

As for progress with the quad, things are certainly coming along. I’ve been doing more and more programming. I’m working on straightening out the syntax to run things between integer math and floating point, since the prop forces you use floating point for trig relations (at least at my programming level).

I finished the controller board for a mini quad my bro wanted to make. I’m going to make myself another version of it for this quad to try to tidy things up and make cable routing easier. Here are some pics of the final product.



And since this could be finicky software I’m writing, I bought some 3 dollar 9g servos from hobbyking to make a bot to test on. I’d much rather ruin them.

Love the little Quad all you need is tracks LOL :mrgreen: is the 3d printer made from flat sheets that i can laser cut or is there some 3d parts i will have to buy besizes the extruder and electronics.

kind regards
Dean

P.S. we want video :smiley:

A cute 3 printed quad! I love it! Any videos of it walking?

HAha Love it.
very cool.

Thanks Guys!

I’m hoping next week I’ll at least have the thing doing some body translation and rotation. We’ll see. Maybe Video?

And CodeMaster. The majority of the printer is 1/8th inch G10, and there are quite a few printed parts.

Ok, not translation and rotation but it’s moving!

The video is still a little rough, I need to scale the motor throttles in turns so the tracks don’t skip and I want to try rescaling the turning radius inputs so that they’re not as sensitive at the edges of the joystick throw. Also, as you can see, it can definitely turn right, but for some reason turning left makes the servos very jittery. I’m a little stuck on this because the code is nearly identical for both directions. I’ll work on it. Also, I’ll try to get a vid up with fresh batteries so it zips around a bit faster.

:slight_smile:

Really looking forward to seeing additional videos.

awesome its coming along nicely looking forward to see it walk

It walks!

The video is just it walking, running through the gait engine loop, no remote control. The weight shift is sinusoidal and only sways 4cm in the video, I had it up to 10cm at one point but it didn’t make too much of a difference. The step length is 6cm, the step height is 5cm and the gait speed is somewhat low. It’s still a little rough and rocky, I need to really zero in on the true servo centers. But, I’m just happy that it’s finally walking. I’ll work on body rotation and translation next. Then I’ll work on the transition to tank mode.

Looking sweet! :mrgreen:

Another video. Got the rotation and translation working. I also found a math error in my code and things are quite a bit more accurate now. At the end of the video there’s a short clip of a long step gait. I set the step length to 14cm and also changed up the gait sequence a little. Looks much better than my first video.

haha cool that’s awesome alittle more tweeking and its ready for world domination :mrgreen: or at least living room domination anyway LOL :laughing: :laughing:

Kind Regards,
Codemaster

That’s the type of robot most people imaging stays only in the virtual realm of video games… very well done!
