Hi all, I'm new to this forum and new to building robots.
Got some inspiration from DJ Sures 1980's Omnibot build.
I've got myself a EZ-B v3 control board and an old omnibot but was wondering if there is a way to purchase the rest of the kit or at least the wifi camera for v3?
If not any advice on the best servos to use would be appreciated. I have been looking at AS-17 servos and HXT 900s.
Thanks for taking the time to read my post and hope to hear from anyone soon
Ken.
So I've seen this battery and the charger under £40.00 for the two. Here's the links to them, any opinions please? http://www.tjshobbies.co.uk/product_info.php?cPath=22_32_67&products_id=83 http://www.tjshobbies.co.uk/product_info.php?products_id=644
Looks fine to me, just be aware that LiPo chargers often come without the power supply which may be extra (and if high current quite a bit extra).
Well thought I better start stripping him down whilst I have the time. Then it's a visit to the robot spa
The bit that's the most fun
Tip: Don't put the dome in the dish washer, mine scratched Melvin's visor. Cool and gentle wash, not the thorough one, you don't want to melt it
That's if you are putting it in the dish washer.
Cheers, took your advice and left the dome out
Didnt bother with dishwasher tabs.
I have another omnibot not comunicating with the remote which is in need of a transplant. Its shell is in nice condition, it's not lost it's colour so I will be fitting this board inside it and keeping it original
So I've got all my bits ordered to make the transister swiching circuits thanks to Rich
and I've ordered a motor driver 1A duel TB6612FNG to control the original omnibot motor.
I've got IR sensors QRD1114 and HC-SR04 sensor on the way aswell as various resisters and cables and servos.
Do I need to order a voltage regulator or can most things connect straight to the ez-b?
Also I may just stick with my 6v 4.5 Amp omnibot battery for now and see how it goes.
Is it a V3 or V4 EZ-B?
If V4 you will need to regulate the HC-SR04 to 5V. If V3 it's already regulated.
Not 100% sure on the TB6612FNG, mine is wired from the V3 so +5v but the V4 doesn't regulate so will be battery voltage. I'll check the datasheet when I get home.
Servos you will need to check. If they are the EZ-Robot ones they will be fine on anything up to 7.4v otherwise you may need to regulate to 5V or 6V.
It's the V3 EZ-B thanks.
So will I be ok to wire the TB6612FNG straight from the V3 EZ-B board to the motor?
My MG-995 Digital servos use 4.8v to 7.2v so they should be okay I presume and my HXT900 servos for his grippers use 3v-6v. I also have a AS17 for his head.
Thanks again, your help is very much appreciated... I've got so many ideas for my bot just need to not try and do too much at once lol.
