Tamiya Twin Motor Gearbox with Wireless Remote Control Help!

Hi

There is this question that i have been searching the net for the past few days but without any results

Is there anyway we can connect the twin motor gearbox from tamiya to a wireless remote control directly without any usage of programming and servos needed?

Please help

 

Thanks a million

Can you be a bit more

Can you be a bit more specific about what you’re trying to do? Are you just trying to build an RC car? Also, what kind of remote control are you using? Is it a TV remote control, RC transmitter? Do you have a receiver (the thing that you put on the car/robot to receive the remote’s signals)?

Although programming might seem scary and complicated, it might actually make your project much simpler. It sounds like whatever you’re trying to do is fairly basic, so you might be able to get a $3-$5 Picaxe microcontroller to get the job done, and many people here could help you figure out what code you need (it wouldn’t be much). That’s something that other people here can tell you more about than me, though, and they, too, will need to have a better idea of what you’re trying to do in order to help you out.

Hi Thanks Mr CleanI would

Hi

Thanks Mr Clean

I would try to be more specific this time. First of all, I’m a Design and Technology teacher

My objective is to create a simple plastic car which the students (age 12) can make by themselves.

However, I would like them to use a Tamiya 4 speed twin motor as I would like to spice things up for them

Thus for those students who are interested in taking part in a competition end of next year,

I would try if possible to connect a receiver or something to the 4 speed twin motor directly (the current transmitter i have is a RC transmitter that ESKY use to fly their helicopter lama V3.

I’m thinking if i can make a simple receiver that can be used onto the motor so that they can move the car they make wirelessly.

However, due to budget constraints and i do not want the students to spend too much money, the receiver must be able to take out easily from one car to another without much hassle so that 2 cars can compete at one time and 2 cars can be assembled for the receiver at the same time then they switch the 1st 2 receiver onto another 2 cars later for upcoming fixtures

 

Hope that its clearer now

 

Thanks a lot

Yes in short

Make a simple RC car

Thanks but with parts easily available at my side (like making use of Tamiya Motor)

RC receivers only do short signals

Generally, RC receivers only do one thing : generate 1 to 2 millisecond pulses every 20 milliseconds to signal the servos or additional electronics what to do. Additionally, the electrical charecteristics of a receiver are such that they would not have enough current to supply the Tamiya motors directly and could burn out trying to do so.

I don’t know about the ESky receivers, as documentation seems scant. It appears they can speed control 2 motors through FETs on an board, but not reversing the motors. I can’t find if these receivers are even available seperately from a heli.

Possible cheap solutions

Hi

Have you also sent me a question thru youtube ?

I would like to know if you have knowledge in electronics ? If so, I know a very cheap solution without using a microprocessor.

You can try the PT2262/PT2273 encoder/decoder pair IC with a ASK RF module. In my region one set is sold at about $3. It can send four bit code by pushing buttons. On the receiver side, you just need to connect the signal pin to a transistor or whatever motor driver circuit like L293D.

Unfortunately I can’t find these kits selling in US. But I saw some discussions in electronics forums. Thus it is possible to get the chips, I guess.

Or, you can try using infrared, a TV remote to control the cars. It should not be difficult to buy the IR receiver kits and connect to a motor.

HiYa. I sent a question thru

Hi

Ya. I sent a question thru Youtube to you.

Thanks anyway

I have got myself a toy that is powered by 6 1.5V batteries (which is also 9V then). That toy is attached to the receiver and 2 motors.

Now I’m wondering if I could change the 2 motors from the toy to fix onto the 2 Tamiya 3V motor that I meant to have.

And may I know what is a 5W resistor? Does that solve the problem of having different motors from the Tamiya?

 

Please advise

Thanks

(Just wanted the kids to enjoy the lesson that’s why I have to put in some effort on my own)

HiI believe most of the toy

Hi

I believe most of the toy motors are small and quite likely they are 3V motor. I suggest you measure the voltage of your toy receiver output to see if it is acceptable (say below 4.5V).

Otherwise, a resistor can help to reduce the voltage. Since you are new to electronics, I suggest you check out the toy’s receiver voltage first. Very likely you don’t need to put a resistor there. By the way, can your toy car’s motor move in two directions, or just one direction ?

the toy tank that I have got

the toy tank that I have got can move front, back , left and right using the remote control

it is controlled by the 2 motors attached to the rear wheels
