I recently tried to assemble the Rover, and my motors are not working when i power up the robot. I have the basic V1 model, and i had trouble with the motors awhile back as feel, because i didn’t solder the wires, but i tried to crimp the improperly. anyways i just tried to solder the wires to the motor leads, and the motors are not working, i have the battery connected, i uploaded the code, and assembled the robot completely, but the motors won’t work when i turn it on.
Did i possibly burn the motor leads when i soldered, if thats possible, or is it something else. Since i wasn’t sure how to solder wires to motors, i looked it up, and it said to tin the wire, tin the motor leads, and then put the wires on the leads, and apply the heat, which i did, and i added a little extrta solder as well. I’m not sure what i did wrong, any help would be great.
P.S. since i initially screwed up with the motors, i assembled the robot before i solder the wires to the motor, i don’t know if that changes anything. also I’m new at this so i may have screwed up something easy.
ill work on posting pictures soon, but i previously tested the motors prior to soldering by using a 9v battery and a battery strap, and both motors turned, it may be the board that isn’t working, but what do you mean additional wiring, i had to use copper 18 gauge wire, because i completely ruined the black 22 gauge wire.
I’ll try to have the pictures posted within the next day or two, and i’ll take another look at rover, and see what I can figure out.
Can you provide an image of the motors and another which focuses on the leads? If you did burn the motors, 4.5V motor and 6V motor replacements are fortunately very inexpensive. You may need additional wiring. The easy way to check to see if the motors work is to connect one directly to the battery; unplug the battery holder from the board, and remove the DC motor from the gearbox. Add 4x AA batteries to the battery box, and plug in the wires from the motor directly inside the white JST connected of the battery holder. If the motor does not turn, it’s gone, and you’ll need replacements. If it does turn, then put the motor back inside the gearbox and try again. If this works, then the board may have an issue. We await your reply here.
Exactly - given that we provide enough wiring for the four motor leads and a bit more, if you are planning to purchase additional motors, you’d need the wiring again. Note that 18 gauge is a bit thick for such small motors; you should use 22 or 24 gauge.
