@bdaouas No specfic reason, Only that I use to work with brushed. :) But sure I give the brushless motors and test. I was looking at the recommended motor and saw that you recommended a motor with KV(RPM/V): 880. That´s quite low?
Thanks @Rickhendrix.

Update on the build:
So First Part For The Robot Is Printed! I use PrimaSelect PETG @240C.

Part 4 has completed 3D printing and the 5 part is printing now.
When The 5 part is ready I will have a good overview how to bottom chassis will look like.

I also going to change from the robot drive system, I was first thinking off using DC Brushed Planetary Geared Motor but instead I will go for 6355 Sensored Brushless (BLDC) motors 190kv running on VESC and belt drive.
Some first sketches on the new drive system:

I have decided to change motors to brushless with belt drive running on on VESC. This is the first sketch of the system

Cables fit nicely in the support beam. I can use 6/8 slots to run cables cross body (I hate messy cables) :)

The design is coming together quite nicely. Planning for any color highlights / accents?

Might want a highlight color. Reminds me of a black and white BMW.

Shafts are now ready. Splitting the shaft from 500mm to two 240mm. Grind top and bottom and bearings fits like a glove.

Test assembly with 3D printed motor brackets and wheel hub. Everything fits perfect! I will add some extra mountings for the the vertical support beam. Other then that I think they are ready for CNC milling.
