DFRobot 2WD Platform Wheels
Maus 2012-01-19 20:50:51 8084 Views7 Replies Hi all,
I found this forum from the LetsMakeRobots.com site and thought the folks here might be able to help me.
We bought one of the Arduino 2WD platforms and after struggling with the wheel encoders for a while we finally got them installed. We were excited. Then we tried to put on the wheels that came with the kit, but they would not slide onto the wheel mount. The opening on the wheels seem to be too small for the white tab part.
What do people do in that situation? Do you just sand down the white part of the motor or open up the wheel slot more? Buy new wheels?
Thank you for any help.

2012-01-20 22:20:21 Thanks for the additional info on the wheels. I'll try to sand down the bulging parts of the wheel slot in the near future. We just want to play with the thing right now! It's assembled and we've checked that the motors, Ping, and sensor mount servo all work. We just need to test the encoders and try to get the wiring under control. It's a mess.

That's great news, but I really encourage you to sand down the wheel, it will help in case you need to remove the wheel. otherwise it will be very difficult to remove later on...Don't worry, we know those wheels are difficult to work with, if you damage them in the course of trying to sand them down, we will happily send you replacements. But, we know there is a solution that will help us avoid the cost and get a working robot in your hands that much quicker.
Happy hacking! Hector

We have used the edge of scissors before and had success sanding down a bit of the wheel opening. you will notice that one side is completely flat and the other has a bit of a bulge, just sand that piece down a bit, try inserting it, until it fits snuggly. it should not have to be forced too much. If you force it too much you might brake the motor's access. Hector

I put the wheel on the counter and pressed down on the motor and the frame at the same time. It took some effort and the frame was bending a little, but the wheels are on.

I'll try applying more force first and see if I can't get the wheels on that way first. I am nervous about breaking something since this is our first build and I'm not sure how much abuse these things can take.
If that doesn't work, I'll hit the wheel openings with some sandpaper and see if I can't get things going that way.
Either way, I'll post my success or failure here after tonight's build time.

Maus 2012-01-19 23:15:02 Hi Maus,
I think it would be better to sand down the wheel opening rather than the motor shaft. If you sand down the motor shaft it could possibly weaken the shaft and cause it to break when more pressure is applied.

Yep. We figured out that few wheels have such problems. And we did some tests with successfully installed the wheels just by applying more pressure on the wheels.
If it not works, use any tools you can find to grind the motor shaft a little bit, a scissor will be enough to finish the job.
