DC Motor Connector Angle

#27

Correct PWM = 255 . 2 different sets of AA Battery. The motor will not turn on spot. I too purchased from RadioShack.

765361255974 Order Number?

Hi @Jachred,

What I mean here is you could buy 2 motors on our website and tell me that order number.

Thanks!

#29

Your order ID is #23826.

Oh. Well that is very nice of you.

hi i wasnt sure where to post my 25mm dc motor problem because i purchased a ultimate robot kit from radio shack with cash.
my connector angle is also incorrect and the motors seem to not be able to handle the work load of the entire tank.
the robot arm works great.
is there a way to use the bigger motors as drive motors?
i would really like that…

thank you.

#31

my roommate and i also are having this problem with our starter kits. i love the quality of everything except the motors. i thought something was wrong with the coding but started searching for a solution online and found this. i would also like to know if we can get replacement motors and im curious on what exactly when wrong with the production.

thanks ahead

Johnny,

I purchased my robot kit from Radio Shack yesterday. I have assembled the bluetooth robot kit and it will not turn on carpet and I even bought brand new batteries. Please let me know if I can order the replacement motors. Also, the connectors were mounted sideways on mine too. The rest of the kit was pretty nice. The white rivet things come loose, so my bracket sits loose on the frame. Is there a better way to mount the bracket to the frame? Thank you for your help.

Mailed in my info, and recieved my replacement motors. What a difference! Zoom zoom.

Thanks Makeblock. More awesomer product, now watch out for your vendors.

I just bought two of the makeblock starter robot kits and I am having the same issues. My motors are soldered with the bracket straight up. They are way underpowered. I even swapped to a 12v battery pack with no improvement. I have one IR version and one Bluetooth. Both have the same issue. Any way I can get my 4 motors replaced also? Besides the motor issues, the robots are great. Wish they had more parts at Radioshack.

#36

I have the same problems. Not enough torque and connectors soldered wrong.https://youtu.be/jcyFzR7A6pQ

Shane that it’s June and still the same issues as four months ago.

#37

@shaiss: ask Makeblock for replacement motors. I got mine and they work much better (in addition, I got 12V accu kit)

#38

BTW, the replacement motors have the same connector angle problem (it is rotated by 90 degrees) and therefore the connectors are facing downwards in the tricycle model.

#39

I’ve been asking, in many emails, twitter, g+, forum posts, no luck. I keep getting the “we still need to prove it’s faulty.”. Even after photos and videos. Just frustrating. I have 3 kits and 6 defined motors and 2 disappointed kids watching their robot as a paperweight.

Maybe one day pioneer will decide to replace my motors.

Did you get the new bracket design with the socket screws? I believe that’s the “new” version.

#41

No, they sent only the motor. I didn’t know they changed the bracket.

#42

This is the new one:

The old one:

Note that in the new one you also get socket screws and not Philips.

#43

Glad I’m not the only one with this issue. Spent hours building it then had it nt work right. Was very frustrating, and thought I did something wrong. I emailed my info to the address listed, is there anything else I need to do to get a replacement or facilitate the process?

#44

It looks like many of us have the old manual. The new manual @ https://onedrive.live.com/redir?resid=5AB8C37D5C75CE9C!12647&authkey=!ABo2IxueJK9fB3A&ithint=file%2Cpdf has the updated diagram that shows the connectors pointing vertical rather than horizontal. I believe this is a workaround as it’s really the bracket or motor that needs to be redesigned as horizontal is optimal. For 1, in the up vertical position the front connector is blocked by the board, so you have to point that one down. When you do that, anything the robot runs over, ie clothes in my case, get caught on the connector.

MakeBlock isn’t offering a connector/bracket replacement at this time. They are replacing the motors, which I have a feeling will have the same mounting issues.

If you need the motors replaced, that will take several emails to MakeBlock support. see http://forum.makeblock.cc/t/notification-replacement-of-25mm-defective-motor/917/26 for more details

Hi @shaiss, you are right. I have the new bracket but I was referring to the older manual. The new connector angle makes sense with the new tricycle design (but it didn’t work with my printed manual).

This is one of those small design flaws we were talking about in the other thread. It could be easily fixed with a link to the updated manual and it is frustrating that nobody from Makeblock commented on the connector angle issue. I feel that the tech support here doesn’t have a good knowledge about the product. Makeblock engineers mush have been aware about the connector angle change and the subsequent tricycle design change.

Johnny.
I just bought a starter kit and the motors are very weak. Are you still offering replacements for free?
