  1. Tommy Sanchez - EE400D Custom Commands: Arxterra Control Panel & Android Application Creating A Custom Command Command Control Panel Interface Implementation Example

  2. Custom Command Menu:Arxterra App Custom commands will allow you to expand the capabilities of your robot. In order to reach the custom menu, please press “Custom”. If you don’t know how to connect to the app or don’t have the app, see the Getting Started tutorial.http://arxterra.com/get-up-and-running-with-the-arxterra-control-panel-android-applications/

  3. Custom Command Menu:Arxterra App Press and hold the yellow icon on any page for contextual help As this is your first time accessing the Custom command Definitions window, you will not have any active commands. To add a new command press the plus (+) button. Note: Pressing “Done” on this page will take you out of the command menu

  4. Custom Command Menu:Arxterra App • The following command types will appear after pressing the plus (+) button: • Boolean • Select • Byte • Unsigned Byte • Short • Unsigned Short • Heading/Separator

  5. Custom Command Menu:Arxterra App Move Up or Down Pressing on any command type will add them to the window space. Selecting an added command in the windows space will allow you to: delete, move up or down, or edit the command properties. Each command’s properties window has a “Command ID” button. This will be explored first before moving on to the command types. Delete Edit

  6. Custom Command Menu:Arxterra App Command ID is used to assign a Hex value to the command. This value is used in your Arduino IDE sketch so the microcontroller can identify what instruction it’s receiving. Pressing the “Command ID:” button on any command type properties window will give you the option to choose from 32 custom command IDs. The range is from 0x40(64) to 0x5F(95). Command types also have 1 or 2 value bytes associated with the command. This will be addressed on the next slides as each command type is covered. (Slide 33-37 explores the byte arrays received from commands)

  7. Brief Overview Of Commands:

  8. Custom Command Menu:Arxterra App To get started with a Boolean command choose Boolean. Once the command is added to the window space, select it and press the edit button.

  9. Custom Command Menu:Arxterra App • Properties for Boolean Command: • Give the command an ID (In HEX) • Give the command a Label (Name) • Include a hover over Tip for the control panel if desired • Choose a Default Value for the selector switch (On or Off) • The command’s associated value (1 byte) comes from the selector switch position. On being [0x01] and Off being [0x00].

  10. Command Control Panel Interface The Interface for Boolean command on the Control Panel Label: Boolean Tip: On or Off

  11. Custom Command Menu:Arxterra App To get started with a select command choose Select. To the left you will see the new command, and to the right the “Options for Select Command”. Pressing the (+) on the right adds more options (choices). Choose an option and press the edit button.

  31. Implementation Examples:Overview Byte Arrays Robot Types Covered Spiderbot/Hexapod Example illustrates: Robot’s sleep mode, walking motion(Gait), stance modes like arched, variable leg motion for defensive leg jabbing, and leg servo speed for quick adjustment to outrun another robot. Rover Example illustrates: Robot’s motor status, special trick movements like weaving, and variable speed for quick adjustment to motors. Biped Example illustrates: Robot’s leg status, walking mode speed, and leg balance options Byte array examples will cover how byte arrays are sent to the microcontroller based on the custom command used. Also, byte array information going from the microcontroller back to the Android phone will be explored.

  32. Implementation Example:A Spiderbot/Hexapod Here is an example of possible custom commands that can be used with a Spiderbot/Hexapod. It will depend on the programmer to choose what best fits their application. If for example you want a variable value command but don’t need negative values to be sent to the microcontroller, you can choose Unsigned when adding a Byte or Short command.

  33. Implementation Example:A Rover Here is an example of possible custom commands that can be used with a Rover It will depend on the programmer to choose what best fits their application.

  34. Implementation Example:A Biped Here is an example of possible custom commands that can be used with a Biped It will depend on the programmer to choose what best fits their application.

  35. Byte Array Explored: Using the Spider/Hexapod example. Each command type’s byte array will be covered. Sleep Mode: This is a Boolean command.It has a Command ID byte and an associated value (1 byte). On and Off provides the associated byte and is represented by 0x01 and 0x00 respectively. Arbitrarily choose the Boolean Command ID to be 0x40. The byte array sent to the microcontroller would be [0x40 0x00] or [0x40 0x01]

  36. Byte Array Explored: Gait/Stance: These are Select commands.A Select command has a Command ID byte and an associated value (1 byte). The options from the list menu or radio buttons provide the associated byte. Using Stance as the example: Arbitrarily choose the Select Command ID to be 0x41 and the Arched, Level, and Recon Option ID’s to be 0x42,0x43,0x44 respectively. if Recon is selected then the byte array sent to the microcontroller would be [0x41 0x44].

  37. Byte Array Explored: Variable Leg Motion/Leg Servo Speed: These can be Short, Unsigned Short, Byte, or Unsigned Byte commands.A Byte and Unsigned Byte command have a Command ID byte and an associated value (1 byte).A Short and Unsigned Short command have a Command ID and an associated value (2 bytes). The value from the slider or stepper provide the associated byte(s). Continue on for example

  38. Byte Array Explored: Using Variable Leg Motion as the example: Byte command: Arbitrarily choose Command ID to be 0x45 and the maximum and minimum for the slider to be 127 and -128 respectively. If you were to move the slider to a value of 30 or 0x1E in HEX, then the byte array sent to the microcontroller would be [0x45 0x1E]. Note: It works the same for Unsigned Byte. Remember that Unsigned Byte differs in that it cannot produce negatives.

  39. Byte Array Explored: Using Variable Leg Motion as the example: Short command: Arbitrarily choose Command ID to be 0x46 and the maximum and minimum for the slider to be 32767 and -32768 respectively. If you were to move the slider to a value of 1000 or 0x03E8 in HEX, then the byte array sent to the microcontroller would be [0x46 0x03 0xE8]. Note: It works the same for Unsigned Short. Remember that Unsigned Short differs in that it cannot produce negatives.

  40. Byte Array Explored:From Microcontroller to Android Byte arrays can be sent back to the Android phone. The reason is to properly display the robot’s present state on the Control Panel widgets. Using the Spiderbot/Hexapod example: If in Recon mode(a mode in which the robot cannot move) an instruction is sent for the robot to move, the Control Panel should reflect a change in its stance by showing Level (a move capable mode). Since as it moves it’s in Level mode. The Android phone would need to receive a byte array of [0x41 0x43] to make the change. (Stance and Option IDs from previous example)
