met with Dr. D today. we are to get him the final list of parts we need. we were talking about specification for the R/C Car in order to make this project repeatable. it really comes down to 3 specs (see bellow). we were talking about different size vehicles. i have noticed in researching different R/C Models that there are different types of D/C motors that are equipped to the R/C Cars. they are either brushed or brushless. Our test car has a brushed motor. brushed motors have 2 wires; a positive (+) and a ground (-) wire only. to control the direction clockwise or counter clockwise, a h-bridge can switch the polarity on the motor. however, with the more expensive R/C Cars they come with a brushless motor. a brushless motor has 3 wires that need to be connected to a ESC-Electronic stability control. then can be controlled.
NOTE: Test Car, removed cover over DC motor and got the part number: Dynamite ECX1071, when to manufactures website and determined it was Brushed.
3 specification for the R/C Car:
1. RTR: Ready to Run
2. DC motor
3. Steering Servo
Question/Idea:
these RC Cars come with a speed controller AKA ESC with both brushed or brushless motors. I want to run a specific test on the TEST R/C car. there is a cable coming out of the Speed controller that is originally connected to the receiver waiting on instructions from the remote controller. instead of hooking it into the receiver i want to hook it into the Arduino and see if I can write a little program to control the speed and direction forward and reverse. if this test work good on a brushed motor it will work the same on a brushless because they need a ESC to run. this would eliminate the need for a H bridge with the brushed motor and also take care of the brushless motors.
Parts list still need. Picking the R/C Car is still a question size, how big of a vehicle do we want. 1/10, 1/8, 1/5.
A good website that has a large verity of R/C Cars and documents components of its vehicles is
