Roboard and Lipo batteries

Thanks both for your feedback. I've spent some time trying to figure out what was happenning. The lipo batteries were placed in the feet of the robot and the robot was moving quite rapidly. I noticed that the aluminium box in which the batteries were placed was a little bigger than a battery and so while the robot was moving the battery was swinging, and may be the swinging of the battery caused it to get hot and the rest you know it . . .

So what I did was that I added some velcro tape to the battery and on the inside of the battery box so that the battery won't move, and this seems to have worked.

Hi, JavaRN,

It is not easy to damage RoBoard's on-board power connector in contrast with other components. So your problem is possibly caused by the connection cable that connects your RoBoard and battery, which may has already loose contact. You may check your connection cable to see whether it still works robustly.

hallo,

i used a rb110 just a few weeks ago. my robot is also bioloid .

i guest that the battery wires to connect the power of roboard is bad connection.

i hope that it is helpful to you

I've been working with lipo batteries for a couple of months. Lately a curious thing was happening - whenever the robot falls, roboard reboots or switches off. So I disassembled the robot, got roboard out and tested it with the battery. Whenever I twist or move the battery (to simulate a robot fall), roboard goes off in the worst case the wires melted!

I thought that this is something that has to do with the battery, so I connected the same battery to a CM-5 and to my surprised it worked, even when I twisted/moved the battery around.

Can roboard's molex connector be faulty? if so from where can I buy a molex connector similar to roboards ready crimpled?
