Just buy a cheap R/C car and use the wires going to the motors for your purposes.
[...] Is this a good option? They seem to be the cheapest transmitter and receivers on the market
I`m in a low budget
(I know more expensive systems would be much better).
I suppose I can connect the two Hitec 311 servos and the Hitec 72MHz Rx battery box directly to the receiver and then everything will work right away without having to configure anything or use any adaptors, right?
I would just buy it all and test it but then if it didn`t work I wouldn`t have enough money to buy another transmitter/receiver.
This is what you should do:Buy an R/C car Disconnect the wires from the motors. You should have 4 wires in total.Now connect your motors to the wires. Two wires per motor.Now you have R/C. For differential drive you would just have the left side of the remote control motor 1 and the right side control motor 2.
I haven't really looked for R/C cars, but from the ones I have experience with, they generally come with one motor for driving, one for steering. The non-tiny ones anyways. And this makes sense. Realistic scale models of cars would look silly having four wheels and differential drive on just the back two.But I could be wrong.
--> Is this some sort of hardware? I dont remember reading any of this in the $50 bot. Are you talking about Teleoperation? If so, it says in the RC page that its optional... If not, then what are you talking about?
In step two of the $50 bot, he said: "Since I had some basic RC equipment around, I made my robot temporarily remote controlled just for fun.[...] I attached a battery to the velcro, and put the receiver inside the bottle. Both servos were attached to the receiver."So when I read this, I thought it was just plug and play. I thought I wouldnt have to configure anything, just plug the servos and the batteries into the receiver, and use compatible crystals in the transmitter and receiver.
I tried attaching the two DC motors to two cardboard wheels (with Scotch tape). I also made a castor (bottle). Well, it doesnt move because I think the motor is not powerful enough (but it worked with 4 wheels in the original car, and they spin when I hold the chassis in the air). So I was wondering, if I use two plastic wheels (I cant use the ones that came with the car because theyre attached to an axle, but i'd buy new wheels) and an omniwheel as a castor (less friction), should it work?
If not, would any of these motors work?---> "Small Johnson" motor (http://www.robotmarketplace.com/marketplace_motorsmisc.html)Speed-380 Motor (http://www.robotmarketplace.com/marketplace_motorsmisc.html)I'm not sure what to look for because some motors say "brushed weapon" or "brushless weapon" (too expensive) or "We recommend using the Sprite-25 speed controller for this motor, or the AUX channel of your Ant 150 controller". . . . what is a "gear box" and how do I know if a DC motors comes with it?
Also, can I attach wheels to the DC motors through cardboard instead of aluminium? (I dont have a drill and I cant attach plastic wheels with scotch tape)
