A political system

We really engineered our drivebase… This took about 1.5 hours to do! Having an awesome programming backend and solid robot base ROCKS!

(Works in 2.x and 3.x, using Tkinter to display)

Enjoy!

Upcoming preview of a game I’m making: TranCyst.

I finished!

Marshmallow gun control system is coming along!

The basic maths behind my arm. It uses this to plot points in its “A-Z” plane rather than some arbitary arcs. To produce lines, it iterates through a number of points along a vector, simulating a line (Though you can’t tell the difference, as each point is 1/6" apart.).

So I kinda just… threw this together in a few hours.

Its gonna be a pretty awesome fair project when I’m all finished.

Ill post up a diagram/thing with all the maths behind this… because there is really a lot more than meets the eye here.

nettlesnettlesnettlesnettles:

In a strafing kilough drivetrain, for omni wheels are arranged in a pattern similar to this, with 90 degrees between each wheel. With 90 degrees between each wheel, all wheels lie perpendicular to the “turning circle” of the robot. It seems that the same principal would apply with standard FRC robot wheels, to a lesser extent. A very small alignment change may be detrimental to the forward-backwards motion of the robot, but would aid in turning.

This would be very detrimental. Especially to low speed movement.

Fancy Pancy Driverstation

So, on MetalCow we made a fancy pancy driverstation. I uploaded a pic, and the electrical skematic of the light.

NOTE: Our light was soldered backwards after some issues and we didn’t feel like physically fixing it, so thats why the code is different than you might expect.

Here’s the code once everything is setup:

#include <Servo.h>

Servo lights;

const int sensorPin = A0;

void setup(){

  Serial.begin(9600);

  lights.attach(13);

}

int i;

bool up;

int prog;

void loop(){

  if(analogRead(sensorPin)<256){

  if(i<=-50)

    up=true;

  else if(i>=90)

    up=false;

  if(up)

    i++;

  else

    i–;

  lights.write(i);

  delay(6);

  }else if(analogRead(sensorPin)<512){

    if(i<=-50)

    up=true;

  else if(i>=90)

    up=false;

  if(up)

    i++;

  else

    i–;

  lights.write(i);

  delay(2);

  }else if(analogRead(sensorPin)<750){

    lights.write(90);

    delay(5);

    lights.write(0);

    delay(5);

  }else{

    lights.write(70);

  }

}
