If the motors are small enough, wouldn't it be possible to use 2 motors in parallel on the esc's and use differential drive?
Also saves the trouble of making a steering mechanism.
they won't spin the same speed, even with the exact same voltage.
Anybody that think of parts of the robot construction as "trouble" should probably choose another hobby
Ok, so now i understand that it is possible to have several motors to 1 ESC.But i am really new to this hobby and i dont know the difference between having things in parallel or series.If someone could give me an understandable definition of parellel and series that would be great.sorry if i sound stupid by the way
But if the wheels are on the ground, they will have the same speed as long as there is no slip. If one has more resistance, it will draw more current, right (please forgive me if I'm wrong, my electronics is quite rusty)?
Anyhow, just thinking out loud here.. I come here to learn too .
I'm just saying that creating your own steering mechanism is more difficult than mounting 4 motors at each corner. For a first time builder, that might be important. Me, I chose an R/C car as a base for my robot, I was not that keen on building everything from scratch yet, because I don't have the space to create a workshop to machine all the parts I would need creating my own base. I have the knowledge and the expertise, but not the equipment. Also, I might be a bit lazy .
This will probably sound like a stupid question to you all but why will one motor be loaded higher than the other motors?
If there's no slip, yes, then one motor will be loaded harder than the other. This leads to faster wear down, so it have to work even harder and the difference will be amplified and you're in a steadily increasing black spiral.
Learn or question established knowledge?
Also, you need to realize that "trouble" is a negative word, while "challenge" is positive..."The steering is nothing but trouble" and "The steering is a real challenge" actually means the same, but the former is said by "glass half empty" guy and robot building is really for those with a "glass half full", if you catch my drift.
