How To Let Jd Turn Left Or Right

i notest that jd cant turn.so i start thinking whits i mostly do.
what do you think off this 3d part.you can mount something in front and back,(rgb-sonar.)
let him turn left or right,and he gets a little taler.i notest whit the exsperiment,
that jf or another robot have a problem whit the hiel comming together.
so maybe we can solve this by letting jd take little steps,2 to make a kwart off a circle.

what do you think.thank for reading.

JD can turn, he is just a little slow and/ir wide (need to have one leg step further than the other). I have seen him do it with my own wyes at the DC tech show I met DJ and company at.

That being said, with the right ez-bits, something like your idea, or just a servo as a swiveling hip joint could give him more mobility.

hi good to hear.i try it whit bioloid parts and still have a problem whit the hiel.
and bioloid servo's are smaller .jd bracket is 6 cm.

JD turns. But it's a little slow. You can add more servos to his legs:) I'll let you expirement with new ways:D

That's the fun of ezbits!

yes i find it very interesting why things are build as they are.
for excample the diff when a horn is down or upwarts.
i found out when putting the horn down,you get more space between the hiels.




love to see a video off jd when he turns,

thank you dj

I don't have a video handy, but this is an option to make him walk more "life like" with the ability to turn easier... you can get creative and try a few different ways:)

Since we are talking about turning....

Will the DC-ss503v still be the recommended compass?
#9  
Its here as one of the controls of the ARC software.
I noticed it wail working with the ezb v3. and was wondering if it is still the recommended hardware for the ezb 4 as i would like to add one to Hexi and JD.

That compass will always be supported, but we have been looking into a few others and have not made a decision yet.

Many addons are being developed which will be released before Christmas:)

GPS. Compass. Localized positioning system. Ez smart servos. Accelerometer. Gyro. And a few adapter boards to support/dominate other products.

I think a gyro would be better than a compass for precise turning... Unless you need to turn to a precise heading, in which case a GPS would be better...

@DJ... Hmmm, can't wait for your Localized positioning system and the Ez smart servos sound very intriguing...
#13  
Dj, your team and your self should make like an Ez-Neural Network for artificial intelligence. I think that would be awesome

Actually gps can't tell what direction you are facing unless you are moving at least 1km/hr. That is why most modern Gps and smartphones have electronic compasses. Many will auto calibrate the compass when you are moving, so if they lose calibration from magnetic interference they will get it back automagically.

Thanks Alan... forgot about that... I should have remember being that I have a couple of handheld GPS units that I use....

Not to mention GPS doesn't work too well indoors:)
#17  
@Rich... I have a Garmin Montana 600, which appears to have a supper sensitive receiver as it can grab signals and maintain a fix even in my basement...
#18  
My Smartphones that use aGPS also have no trouble getting a fix indoors, although at best, an aGPS receiver has about 1 meter accuracy. Need DGPS and long sample times to do better than that. A GPS without cell tower assistance will be 2-3 meters under optimum conditions.

There are some designs for "indoor GPS" that we might start seeing in large buildings like malls and convention centers. Will probably use a combination of WiFi and/or Bluetooth triangulation and require smartphone software or new receivers to work. Standards are a long way off, but some pioneers may start deploying their own solutions before any standards are published.

Earlier designs used transmitters that spoofed or re-transmitted the GPS signals indoors, but at least in the USA they ran afoul of the FCC and DOD so those ideas are essentially dead.
