How do I write code so that when I push the joystick up and left at about 45 degrees, the robot turns left forward? Push the joystick up and right at about 45 degrees, the robot turns right forward. Push the joystick down and right at about 45 degrees, the robot turns right backward. Push the joystick down and left at about 45 degrees, the robot turns left backward.

Code:

if (joystick is up and joystick is left at about 45 degrees)
{
  robot turns left forward
}
if (joystick is up and joystick is right at about 45 degrees)
{
  robot turns right forward
}
if (joystick is down and joystick is left at about 45 degrees)
{
  robot turns left backward
}
if (joystick is down and joystick is right at about 45 degrees)
{
  robot turns right backward
}

I'm trying to write code that lets me use Esplora board to control a robot. When I start the code, it is supposed to set up the servos to center position but nothing happens until I press the joystick button. How can I fix the problem?

Code:

#include <Esplora.h>
int walkflag;
void setup()
{
  Serial1.begin(115200);
  if (Serial1.available())
  {
    robotstand01; < nothing happens here
    delay(500);
  }  
}
void loop()
{
  if(Esplora.readJoystickButton()==LOW)
  {
    walkflag = 0;
    robotstand01(); < it works.
  }  
  if(Esplora.readButton(JOYSTICK_UP)==LOW)
  {
    walkflag = 1;
    robotwalk01();
    robotwalk02();
    robotwalk03();
    robotwalk04();
    robotwalk05();
    robotwalk06();

How do I have robotstandtowalk01() subroutine/function execute once? Is it possible to use the code in BlinkWithoutDelay sketch instead of Delay(1000)?

I connected Arduino Esplora to SSC-32 board made by Lynxmotion. I can use the thumbstick to move my robot. I think that there's a problem with the Arduino code. If I comment out the else parts of the code, the robot walks correctly. If I don't comment out the else parts of the code, there is a slight pause in the walking movement. How can I fix the problem?

Code:

#include <Esplora.h>

  }

Does the machine have E-Stop button that requires you to turn the button to reset the machine? If so, I think that Arduino and relay will not work. Why not get another E-Stop button?

I tried to build a prototype of a robot but I ran out of parts and I didn't make plans for the robot.

What size of garden hose did you use in the low-cost robot hand?

David82, I think that you should STOP trying to do something that may cause injury or death, and may cause damage to property. You CAN'T try to run 120VAC current through Cat5 cables. If you don't believe me, connect two thin wires to a powerful battery (battery pack for R/C cars). Touch the wires together and watch the insulation melt.

I want to create a mechanically correct model and simulate it to make sure that it works before building it. I don't have a lot of money for software.

stevekap25, Does the go-cart have pedals for throttle and brakes? If so, you can add a "joystick" connected to the pedals. The linkages between the "joystick" and pedals would be made so that when the client pushes the "joystick" forward, the linkage would push the throttle pedal forward, making the go-cart run. When the client pulls the "joystick" backward, the linkage would push the brake pedal forward, stopping the go-cart. The linkage would have sliding joints so that one pedal is pushed forward at a time.

stevekap25, Does the go-cart have automotive-type steering? If so, can your client use the steering wheel and use the joystick for throttle and brakes?

I am trying to create a functional model before building the robot.

What about 3D modeling programs such as 3D Studio MAX and 3D game engines such as Unity 3D, CryEngine, and UDK? I tried to use Microsoft Robot Studio and V-Rep Pro (http://coppeliarobotics.com/) but I don't know how to use them.

Are there programs for creating 3D models of robots before building them?

How do I use the accelerometer in Arduino Esplora to control computer games as if the Arduino Esplora is a tablet? I controlled a game on a tablet by tilting the tablet.
