I'm currently running 4 Argos motors at 16.8v with an electronize 30a on each side. My question is what am gaining by running 4 instead of 2? Surely I'm just splitting what the speedo can deliver in terms of power? Forget about traction etc
Thanks

in terms of your speedo it will be doing more work if you like and nearer it limits running 4 motors rather than 2
all the advantages of 4 wheels come in traction grip pushing power etc
Ok, cool. I'm currently building a 4wd flipper and got a little worried about weight!
Also, if Im using a 16.8v battery, how to I get it down to 12v for a solenoid valve or can I just run it at that voltage? Same goes for a battle relay?
i believe both should be in that voltage range
not sure though check with someone else
A 12v solenoid can be run @ 24v as long as it's only for a few 10's of seconds.
The pushing ability is limited by the mass ( weight ) of your robot on the wheels and the co-efficient of friction of the tyres.
The BEST you could possibly achieve is a pushing force in kg's equal to that of your robot.... 0.9 times the bots weight in kg's is probably closer to the max you could achieve
and 4 driven wheels gives this possibility... all other configurations have a percentage of the bots mass sitting on castors or skids thus it's not available to be used for grip.
