Battery Problem

Hi. I had been working through some calibration troubleshooting and fixed some errors (I had been trying to calibrate in Safari which failed but worked fine in Chrome. Also I had failed to hook the little holes over the black pin for the 4 silver motors).

Now when I try to re-calibrate I find that the battery level is low and there is a "squealing" noise. I have plugged it in to my laptop to re-charge but the squealing continues and the blue charging light does not come on. Previously this had worked, although seemed to run out of charge very quickly (as in a few minutes of fiddling with the calibration =/- buttons).

How long should the battery last, how long should it take to fully charge and why might the blue light not come on?

Many thanks Catherine

Hi Robotical,

I have battery problem too when I connect Rick with Raspberry Pi 3. Problem of battery power not enough was also mentioned on this site.

The solution is to buy more powerful battery. However, I am currently living in Japan and I cannot find the desired battery with suitable adapter to connect with Rick. Even I spent all day to search at Akihabara or Amazon Japan.

I can find battery and adapter on other online stores in USA, for example, but they do not ship battery to Japan.

I am newbie of electronic field. Any advice to supply power for both Rick and Raspberry Pi? I could install ROS on Raspberry Pi but now I cannot do anything with it.

Thanks, Phuong

Hi Catherine,

The charging light should come on unless the battery is fully charged - could you check to see if it works now it's had a bit of charge?

Otherwise please send an e-mail over to support@robotical.io and we'll look at getting a replacement part out to you

I've just tried with an iPhone plug and the blue light flickers on and immediately goes off. I can't tell if it's the battery or the connections. Nothing feels loose

Thanks Catherine

Hi again,

Yes, any USB plug should be safe to use - an iPad or iPhone one should do the trick - could you give one of those a go?

Thanks,

Sandy

Experimenting a bit more, the blue light comes on when I plug into laptop. Then charges for a minute or 2 before the blue light goes off again. I'll try the mains when I know if our plugs our safe to use

Thanks Sandy. Please could I just check - is it safe to use any plug with USB adapter? I have iPhone or iPad ones? Are they ok?

I have just plugged into my laptop again and the blue charging light is now coming on again. So it seems to be an intermittent problem. As far as I'm aware I've done nothing different! But I'll see if it fully charges this time

Thanks Catherine

Hi Catherine,

Sounds like Marty might not be getting charged up properly - the battery should last for an hour at least when charged up, and often a lot longer. It will normally take 2-3 hours to charge up fully.

Could you try plugging in to charge when Marty is turned off, and seeing if the blue charging light comes on? If it doesn't could you try charging from a wall socket USB adaptor?

Thanks,

Sandy
