Integrated Encoders

This is the standard setup that uses built in motor encoders.

left_motor_ports a vector of left motor ports, negative reverses the port. first motor is used for sensing right_motor_ports a vector of right motor ports, negative reverses the port. first motor is used for sensing imu_port the port an imu is in wheel_diameter diameter of your drive wheel ticks cartridge rpm ratio external ratio of your drive. should be wheel gear / motor gear

Prototype

ez::Drive chassis (
  // Left Chassis Ports (negative port will reverse it!)
  //   the first port is the sensored port (when trackers are not used!)
  {1, -2, 3}

  // Right Chassis Ports (negative port will reverse it!)
  //   the first port is the sensored port (when trackers are not used!)
  ,{-4, 5, -6}

  // IMU Port
  ,7

  // Wheel Diameter (Remember, 4" wheels are actually 4.125!)
  ,4.125

  // Cartridge RPM
  ,600

  // External Gear Ratio (MUST BE DECIMAL)
  // eg. if your drive is 84:36 where the 36t is powered, your RATIO would be 2.333.
  // eg. if your drive is 36:60 where the 60t is powered, your RATIO would be 0.6.
  ,2.333

Example

Drive(std::vector<int> left_motor_ports, std::vector<int> right_motor_ports, int imu_port, 
double wheel_diameter, double ticks, double ratio);
