Right now I have a robot with 2 driving wheels and 2 caster wheels that I want to change to use 4 of the driving wheels I have. Reason for upgrading is to avoid the awkward frame I’m using to accommodate the 2 caster wheels (they have different dimensions and mounting that the driving wheels obviously). As well as to avoid the imbalance happening due to the caster wheels.
So the options are to use 2 motors each motor driving two wheels with chains and sprockets or to use 4 motors each for each wheel. That means finding motors that produce half the torque of the current motor, same RPM and hopefully half the power. This has already proven difficult to find, but I’ll keep searching.
That being said, I’m not really sure how to use a single motor to connect 2 wheels together. I found this website that sells rover sets, but then realized they’re actually using 4 motors and not 2 motors. https://www.superdroidrobots.com/Robots/robotic-kits-platforms/wheeled-robots/product=2386 1
Just for reference, these are the components I have currently:
If I go with 2 motors, should I have 3 sprockets (1 motor and 2 wheels) with a single chain? Or should I go with some sort of 2 chains and 4 sprockets? Maybe there’s a sprocket with 2 sets of teeth or something like that.
