Im new here as you probably guessed from the title, but, since im doing quite a unorthodox project, i need an rc car with individual control for a main motor and not one but three servos, what hardware would i need for that? At some point il want too add a camera and a way to be controlled from my computer.
From all the missing information I can only take a SWAG. First determine what the motors require to drive them in volts and current. Do the same for the three servos. Now what else is there, there is a receiver, controller, lights, ... When you have this figured out draw a simple block diagram and label the electrical requirements. For the motor drivers use MOSFET drivers, the bipolar ones drop almost 3 volts when set up for reversing. Now that you have that figured out you need to size the battery, for this you will need to know the run time and average and peak currents. As for a controller you have many options, such as the ESP devices which have an RF transceiver on or maybe a Nano or many others. At this point determine your weight and check if the motor can drive it the way you want.
Well, the motor needs to be somewhere around 12V/100W , that's the most common voltage i found for these kind of motors, as for servos i need 2 high torque with limited traverse and one continuous 360 one with mediocre torque, with them being probably all 5V. So with this information, how many mosfets and boards do i need? Also need to mention that this project is very still in prototype stage, with the whole thing assembled I'm quite sure it will go over 2-3kg in mass, and will need quite a bit of torque since it will be 8x8.
Perhaps you should explain to us what that actually means. A picture or drawing, perhaps. How do you intend to apply the one motor torque to the drive wheel/wheels?
Keep at it, and measure the current draw of the various components as the project develops.
The power and torque required depends on the vehicle design, vehicle mass, speed of travel and terrain to be navigated.
As far as MOSFETs that probably is the best solution but not necessarily so. You need to define the motors much better and if they run in one or two directions. For MOSFETs you need to know the current, voltage, thermal boundaries just to get started deciding which ones you want. Next question how will you control them?
An rc car with 8 wheels, 4 on each side, all powered.
I want to do a Type 16 replica 1/10 size, search it on google.
Can you show us the mechanism you are using to power all the wheels? Will they all turn at the same speed?
Could you provide the forum with a link to what you are actually planning to do ?
I suspect most forum members know how to use Google, but how could they know how if the search results were correct for your project ?
Of course dear stranger, Type 16 maneuver combat vehicle - Wikipedia
Looking at the photo you probably understand for what i deed the 3 servos and a motor, the motor for propulsion , one servo for steering, one for turret traverse and one for gun elevation and depresion
at the moment iv been very busy with work and i didn't yet have the time to make a scheme, but as a general idea there will be the motor to which there will be connected 4 differentials in line to a driveshaft obviously, i think you will get what im saying if you visit the link i posted above.
Also need to say, thank you to everybody who is replying and helping me with this project, i greatly appreciate it. Im sure since i dont know pretty much anything about the whole domain im quite a pain in the ass to help, so, thank you:)
So, you don;t really have a plan or drawing, so good by and good luck.
I have a vision and i have a plan but didn't really have the time to draw a sketch, i just got home from a 14 hour shift and i made a really, really bad sketch of the drivetrain.
