How to use the Sabertooth Kangaroo robot skillMovement panel for the Kangaroo and Sabertooth from Dimension Engineering. This allows a robot with wheel encoders to be used, which enables the kangaroo's speed control and various other features.
1. Software Serial Option Checkbox
This uses any EZB digital I/O port to send an emulated serial signal to control the Sabertooth. This section includes a drop-down for the serial communication speed (baud rate) and a Button to change I/O ports. *note: Software serial should only be used if the ezb does not have hardware UART.
2. Hardware UART Option Checkbox
This uses an EZB UART port to send a serial signal to control the Sabertooth. This section includes a drop-down for the serial communication speed (baud rate) and another drop-down to select the hardware UART number.
*Note: Use the ezb hardware UART if available over software serial.
3. PC COM Option Checkbox
This uses a PC COM port (commonly a USB-to-Serial device) to send a serial signal to the Sabertooth to control it. This section includes a drop-down for the serial communication speed (baud rate) and another drop-down to select the COM port number. This option has the unique feature that allows you to connect the Sabertooth motor controller directly to a computer.
Configure the max speed values for each direction of each channel (Left & Right)
Kangaroo Dip Switches
The kangaroo will need to be configured for Digital input, Quadrature feedback, velocity control, and independent mode.
Use the Auto Tune feature to tune the kangaroo for the robot encoders. Because Auto Tune is a little unreliable at times, use the DEScribe software to verify the settings. If both wheels use the same encoder style, then it's probably a good idea to copy the settings from one encoder to the other, so they're the same.
