This Car No.03 uses similar system as Car No.02, but different chassis Crawler CR-01 is applied, which has optional 2 servos system and that makes crab-driving (4 wheels same direction) or short turning radius driving (front and rear wheels different direction) available. It makes great fun for driving!

Step 1: Procurement

Awesome projects you have made.. what's the best way to map the steering wheel and have the arduino control it? I currently have Uno R3 and Micro..
I don&rsquo;t know what you intend to make. But Arduino Servo library or Software Servo library is good enough to control R/C car. <br>If you need more accurate control, you should use Servo Shield. <br>http://www.renbotics.com/servoshield.php <br>Servo Shield can control 16 servos. <br>You can also make the servo controller with IC chip 4017N using Servo Shield library. (Refer to Eagle Design Files of Servo Shield) <br>
u should put the cam. in the cockpit/driver seat so it looks like ur driving
Thank you for your comment. I will reflect to my further project.
