Hi to all!
I’m designing a mobile robot which will have to draw some lines (straight and/or curly) on the floor while it moves.
The floor will always be flat with almost no obstacles.
The robot will have four wheels and its speed won’t exceed 0.8 m/s.
I would like to receive some suggestions about the wheels: is it better to use omni or mecanum wheels in this case?
I know that both wheels have advantages and disadvantages (i.e., mecanum wheels require more torque when you move sideways), but which one is suitable for this project?
Thank you!
Hey.
This is the coolest drawing wheeled robot that I found:
Looks like he’s using stepper motors with his omni wheels.
Not a specialist in these types of robots but it’s definitely one of the best that I’ve seen.
Hope this helps
thank you for your suggestion! That robot is very cool and interesting!
This is not exactly what I need to do, but it gives me lot of ideas!
What is the advatange to use a X-shape vs a normal 4-wheels configuration?
By X-shape you mean 3 wheels?
With the mecanum wheels you can perform all kind of movement with only 3 wheels.
This mean you will save on a motor and a wheel.
