cia a tutti, io ho lo stesso problema….. il mio pero’ fa il conto alla rovescia e poi parte per un 10/20 secondi e poi riparte nuovamente il conto alla rovescia…. potete aiutarmi????






somewhere along the line it is looking to return to its base. that is what the countdown indicates. Check all the sensors including the lifted-up sensor.

Everything “is in good contact even the battery is 16v when tested” double check the circuitry

thankyou very much @oldturkey03 your answer really solve my problem. i checked the battery canection by bending it side by side while the rebot is on. then i found out that its just a faulty battery connector. and now my robot is back to life. in addition i had change all the CE capacitor because i thought that was the problem hopefuly it will not cause any damage in the future. Btw thankyou again for the regards mr.Oldturkey30 Godbless you!


@salaguste glad it worked out for you and great that you got it working again!!
