Inspired by this website and it's community I have just got hold of an old omnibot for my first attempt at creating an ez robot. As this is my first time I need some help and advice as to what I can and can't do and thought I would put my ideas to you guys and see what comes back.
My first idea is to remove the original drive and replace it with something like the rover 5, has anyone tried or achieved this?
Also I was wondering if there is anyway of controlling a tablet that is built into the omnibot via the ez-b?
I know this one is really out there but any thoughts on wireless charging or anyway of configuring it to charge itself when the battery is low?
Please excuse my ignorance and be kind
The RAD base is very loud. The one I was using for Jarvis was a very bumpy ride too, I wasn't happy with it at all.
What's wrong with using the original Omnibot drive train? Hook the 2 motors up to a H-Bridge and it's a great drive train. It's still a little noisy but not as noisy as the RAD and can be soundproofed with Dynamat to make it quieter. It's fast and powerful too and saves any messing around.
You're quite right Rich, what am I thinking! I need to reign it right back, my imagination is running away with me and I do tend to over complicate things.
Dynamat is a great idea but does it make much of a difference? Any other tips for taming that noisy drive?
Also will the original 6v battery be good enough to power the drive and the ez-b? Maybe I should use two batteries but would the original charge system still work?
I started off using the original 6V SLA battery in Melvin (Hearoid, shares the body of an Omnibot) and it run fine. I upgraded to a 2S LiPo eventually for a few reasons though but the 6v battery will be fine and will run the motors without a regulator and power the EZ-B just fine.
I've not used dynamat on my robot yet but it has been mentioned that it makes a massive difference. If it's anything like when used in a car then it will make huge amounts of difference. Another thing to quieten it down would be to re-grease the gears.
As for the original charge system, I have no idea, none of my Omnibots not my Hearoid come with charger (I guess they go missing a lot). That's a reason why I upgraded to a LiPo (others included higher capacity, smaller size and lighter). If you parallel the batteries then probably yes but you will fill most of the Omnibot with batteries. A 6v SLA is about £7 from Toolstation, a LiPo is about £20-£25 from ebay. The space, ease of use and capacity is worth that extra £13-£18 in my opinion.
