This suggests that a capillary tube may be used for metering the refrigerant mass flow rate in variable capacity carbon dioxide refrigerating systems, even knowing that at low speeds the evaporator heat exchanges will be negatively impacted by the high evaporation pressures.

There was the option for a traditional phone line on my property, but that is, of course, limited to 56kbps speeds at best (way too far away from DSL being an option).

SwerveInverseKinematicsDerivation 94%

Swerve Inverse Kinematics    Inverse Kinematics  The goal of inverse kinematics is to determine the appropriate inputs to a system (in our case,  commands to the turning and driving motors) in order to produce a desired output (a velocity  vector and a rotational speed and direction for the robot). For swerve, we don’t need to  determine what to send the motors directly, since we’re using control loops for that, but we do  need to tell those control loops what direction and speed we want for the wheels.    Determining the outputs  The outputs we want are determined by user input. I decided to keep it simple and set the x  component of the desired velocity vector based on the x­input of the left joystick, the y  component of the velocity vector based on the y­input of the left joystick, and the desired  rotation based on the x­input of the right joystick. I’m considering joystick inputs to be on a  range from ­1 to 1.    Some definitions:  V​  ­­ The maximum speed one of our wheel pods can move  max​ V​  ­­ The desired velocity vector of the frame (componentized into V​  and V​ )  f​ f, x​ f, y​ ⍵​  ­­ The desired rotation of the frame; I’m defining counterclockwise as positive  f​ L ­­ The vertical length of the robot (measured between contact points of wheels)  W ­­ The width of the robot (measured between contact points of wheels)  √ 2 R =​   L 4 2 + W4  ​  ­­ The robot’s radius of turning    Target settings based on my control scheme:  V​  = V​  * leftJoystickX  f, x​ max​ V​  = V​  * leftJoystickY  f, y​ max​ ⍵​  = V​  * rightJoystickX / R  f​ max​   Wheel motion  If there’s no rotation, each of the wheels clearly moves with the same velocity as the frame; they  should all face the same direction and move the same speed. This is identical to crab drive.  Applying rotation changes the target velocity of the wheel. Recall V = ⍵R from physics. Thus, on  the upper­left pod, the target velocity is componentized as follows. (Note to self: add diagram).  ­1​ ɸ ​  = tan​ (L / W) ­­ The angle between the frame and the first wheel pod  1​ V​  = V​  ­ ⍵​  * sin(ɸ ​ ) * R = V​  ­ ½ * ⍵​  * L  1, x​ f, x​ f​ 1​ f, x​ f​ V​  = V​  ­ ⍵​  * cos(ɸ ​ ) * R = V​  ­ ½ * ⍵​  * W  1, y​ f, y​ f​ 1​ f, y​ f​   The following is a table, by physical position on the frame, of the componentized wheel  velocities:  V​  = V​  ­ ½ * ⍵​  * L  1, x​ f, x​ f​ V​  = V​  ­ ½ * ⍵​  * W  1, y​ f, y​ f​ V​  = V​  ­ ½ * ⍵​  * L  2, x​ f, x​ f​ V​  = V​  + ½ * ⍵​  * W  2, y​ f, y​ f​ V​  = V​  + ½ * ⍵​  * L  1, x​ f, x​ f​ V​  = V​  ­ ½ * ⍵​  * W  1, y​ f, y​ f​ V​  = V​  + ½ * ⍵​  * L  1, x​ f, x​ f​ V​  = V​  + ½ * ⍵​  * W  1, y​ f, y​ f​   Note that they are very similar, except for the sign on the rotational influence term. Each pod  inherits the target velocity of the frame, and its velocity components are either added to or  subtracted from by the rotational influence term, depending on where they are.   Determining the wheel pod settings  Now that we know the target velocity for each wheel pod, deriving the target angle and speed  for each wheel is simple.   Θ​  = atan2(V​ , V​  ) ­­ The target angle for wheel pod n  n​ n,  y  ​ n, x​ |V​ | =  n​ √ ­­ The target speed for wheel pod n  (V n, x)2 + (V n, y)2  ​   Finally, because the target speeds may not be in the same range as your motor settings, if any  of the target speeds is greater than 1, divide all target speeds by the greatest target speed.  Room for improvement  Note that this technique does NOT account for the fact that wheels can turn backwards. In order  to reverse direction, it is more efficient to hold the wheel pods at the same angle and reverse  their wheels. However, this technique, when applied on its own, will instead turn the wheel pods  180° at full forward drive power.
