Hello Ezrobot Community, All,
I'm wanting to test InMoov Robot using EzRobot but very unsure of what parts I need to get in the shop, are you able to assist please?
Do I get the whole EZ-B development kit? or just the wifi robot controller is enough? but then I already have a 6V output battery pack, will this be sufficient to power up the EZ-B robot controller and the 5V servos (which I currently use..)? or I need to get the battery in the shop?
Do I need the inline 5V regulator? (my servos runs at 5 volts)
If I can use my 6V output battery pack, do I need to get the alternate power adapter? (from the shop)
I just want to do basic test in controlling my servos with EZ-B.., testing min and max turning angles of the motors,
Thank you for your assist,
Kind Regards, Roger
Hi Roger,
A bus, or bus bar, is a strip of metal that allows you to connect and main power lead( larger gauge positive wire) to one end of the strip and then connect small power leads (from your servo) to the terminals on the strip. You would use one for negative too. The purpose of this is to supply maximum amount of amperage to your servo. Bus bar example
Question 1, yes, no break out boards. Just run the signal straight to the EZb.
3 and 4. I use a corded 6 volt power supply. It's possible your 6v battery has issues and that is why the EZb won't turn on. It is possible that your servo has built in voltage protection and it didn't like the 12 v you supplied to EZb. You do not need a voltage regulator for each servo. You will be doing a lot of testing of servos and such so do yourself a favour and buy a corded (one you can plug in a walll) 6 volt DC power supply . Search power supply on this forum, there are some good links. I'll look later but on the road now.
Have fun! Tony - not sure where bob came from
This type of power supply would work Power supply
Hello All,
Thank you for all your kind help and links, I will test it with your advises.
Hello Tony, (sorry called you wrong name earlier on),
I done some research on your mentioning of the busbar and visited the site at https://www.performance-world.com/Electrical-Bus-Bar-p/321322.htm
Sorry but I'm a bit still confused, this bus bar provides a 12 point distribution of power, so does that mean each point on the bus-bar provides power to 1 servo motor only? so a total of 12 servo motors...., and sorry I haven't used one before,
and for the grounds (negatives connections) from the main battery to the servo motors, it requires a second bus bar, is that correct? just confirming what you mentioned.
(I have attached a picture for this query)..,
Thank you very much for your help and very detailed explanations,
Kind Regards,
Roger
Hi Perry S,
I went back to your threads on converting Arduino to EZB4 and I also saw the photo of your conversion, it seems like you have both systems (MRL and EZB4) running on your InMoov robot,
In your photo, you have the main nervoboard mounted on the Arduino Mega and you printed an enclosure for it and you also have wires sticking out of it and connected to the EZB4,
are those wires just signal wires ? and not power..., (positives and negatives)
and how did you connect the Mega to the EZB4 while having the nervoboard mounted on top? and what did you use? I read that you used jumpers but I'm not sure what it is, sorry I'm scratching my head...,
Thank you for your help!
Kind Regards, Roger
@dory, Your life will be alot easier if you get rid of the Arduino's and breakout boards. You don't need them. Connect your servo signal wires directly to the V4 and power your servos from a 6 volt bus, as described earlier in this thread. I would also replace that 5V servo with a 6V one, that will also make your power supply issues easier. It probably won't last long anyway.
Dory, I tried using the Nervo boards as long as I could because I had already sunk money into them. Bob is right. Let them go and things will be easier. That pic you are referring was something I tried and abandoned.
Thank you @bhouston and @Perry_S, now I understand more behind the picture,
Hi @bhouston,
Sounds good, so if I get this one: https://www.performance-world.com/Electrical-Bus-Bar-p/321322.htm (bus bar) , will this work with my 6Volt 12Ah SLA battery? (attached earlier on.)
I tried searching on ebay as well and it gives me only the 12Volts 6ways Bus bar results.... ( https://www.ebay.com.au/itm/Bus-Bar-12V-6-Way-Electrical-Terminal-Dual-Junction-Box-M4-Stud-Kits-6P/153069557604?hash=item23a3a81764%3Ag%3AgUIAAOSwmGZbKvuZ&_sacat=0&_nkw=6V+bus+bar&_from=R40&rt=nc&LH_TitleDesc=0%7C0 )
Thank you for your help,
Kind Regards Roger
