Exclamation B-robot EVO. OFF ROAD version
It has been easy to modify the original B-robot EVO adding new Off-road wheels (regular 83 mm diameter RC buggy wheels, quite easy to get and inexpensive).
   
More info at: http://jjrobots.com/the-b-robot-evo-goes-off-road/

Enjoy it!

Nice upgrade! How do you attach/fasten wheel to motor shaft? Any photos?

We have modelled a simple NUT for the motorĀ“s axis
You only have to press it as a top after placing the wheel on the axis.

RE: B-robot EVO. OFF ROAD version
I've fitted some buggy tires onto the Brobot EVO 2.
Here they are, they work well.
https://www.amainhobbies.com/aka-chain-l...%2fp450505

Used a wheel mount from a Tetrix kit with a 3d printed adapter.

But as far as the code goes, it seems to work better with the original code as opposed to the "offroad code" linked to above. Any ideas? On the new code I could rarely get it to stand up without stalling the motors.

RE: B-robot EVO. OFF ROAD version
The behaviour will depend (a lot) on the Wheels diameter and the new centre of gravity.
We are about to upload a new code for the B-robot EVO 2 (now it is easier to stand up).
Can you let us know the wheel diameter and if you are using the regular 6xAA battery holder or any other power source (LiPO...)

Neat, I look forward to trying it. subscribed.
These AKA wheels from the link above measure as:
83.4mm (3.28 in) hub diameter
112.4mm (4.42 in) tire diameter

I'm using the six AA holder that came with the robot and I use NIMH.
Only changes are a GoPro mount (no GoPro while testing), USB cable (easier to program) and some tiewraps.

Testing the new code! (potato quality video attached)
The Offroad version was tested after the race and adjusting the control PID parameters...
