I ordered the B-Robot EVO 2 end of last week, received it here in south of France on monday this week.

I needed approximately one hour to build it and I immediately realized that the wheels were badly printed. The center was plain circular instead of D shaped. For that reason the robot could not stand.

I thus ordered a set of wheels from Pololu with the adapters on tuesday night, received today by Fedex, installed in 5 minutes and it worked like a charm immediately.

I cannot send a video because I played like a kid and my nimh batteries are recharging now ... I will tomorrow.
I realized that the arm servo is a bit weak and that it cannot lift the bot on the ground, but it does on my desk with a glassy surface...
I'll check for a stronger servo, if it is not possible to feed this one with 6 V ?

Kudos to JJrobots team ! That's an impressive and fast robot.

Thanks for the comment Dan!
Could you please send us a photo of the hubs? We test the wheels + hubs prior sending them and the motor shaft should fit properly inside (the hub is D-shaped)
Check the photo below. Sometimes is not easy to notice where the "D" is pointing to, but if you place the shaft properly the wheel will work as intended. Do you want us to send you a replacement?

So, your B.robot navigates with your custom wheels nicely? ;-)
Send a video!
