![]() Encoder Target: When using Run to Position Mode, this value sets the target position for which to rotate the motor and hold position. Controller Daisy Chain Position The position in the daisy chain that corresponds to the motor controller box that you wish to communicate to on the bus. Select Channel: Target motor channel to control (Motor1 or Motor2). It will do this by using a maximum rotation rate as set by the value wired to the power terminal. Run to Position Uses built in firmware PID which results in the target motor channel to run the motor to make the current encoder value to become equal to the target encoder value. The rotation speed and direction is set by the value wired to the power terminal of the VI. The speed of the motor will compensate for changing loads in order to maintain a constant motor speed. Constant Speed Uses built in firmware PID which results in the target motor channel to run at a constant speed by using encoder feedback. Control Mode: o o o Power Only Sets the target motor channel to run in open loop mode at the power level and direction value wired to the power terminal. This function is primarily intended to harmonize the forward and reverse directions for motors on opposite sides of a skid-steer chassis for example. Error in Error data in Error out Error data out Reverse? : True or False Selecting true will reverse the direction of the target DC motor output channel and encoder input. Move a TETRIX DC motor with Power/Direction, Constant Speed, or Run to position mode command. ![]() Motor Channel Target motor channel to control (1 or 2). 3Ĥ Stops DC motors with a brake or coast characteristic. A maximum of four controllers can be daisy chained together. This will provide battery power to the myrio controller. Plug the DC barrel jack into the myrio power input port. To connect power, wire a RED jumper wire between the positive terminals on the motor controller battery terminal strip and the DC barrel jack adapter, then wire a BLACK jumper wire between the negative terminals on the motor controller and DC barrel jack adapter. A DC barrel connector to terminal adapter is included in each TETRIX myrio bundled set. Power to the myrio is fed from the open battery position terminals on the last controller box in the daisy chain. The I2C connection cables are the LEGO NXT style cables, which are included with each HiTechnic controller. A maximum of four controllers can be connected in a single daisy chain to each myrio MXP port. Subsequent controllers will be set to Positions 2, 3, and 4. The motor controllers are connected in a daisy chain hookup with the first controller in the chain being designated as Position 1. ![]() 2ģ The HiTechnic controllers connect via the Pitsco adapter to the I2C bus of the myrio controller. An adapter interface board developed by Pitsco and included in each WRO TETRIX myrio bundled kit must be used to ensure proper connection and I2C communication between the TETRIX HiTechnic motor controllers and the myrio controller. 1Ģ Each of these VI tools can be used to construct a LabVIEW program for controlling a TETRIX robot equipped with a HiTechnic motor and servo controllers and myrio. After the installation is finished, the installed TETRIX myrio programming VIs can be located on the LabVIEW programming palette. Follow the prompts on the screen to complete the installation. First robotics labview xbox software#After the VI Package manager software is installed, double click the VI Package file once more to start the installation of the tools. Simply follow the prompts on the screen to guide you through the process. If you have not already installed the VI Package manager software, you will be prompted to do so. Installing the programming tools To begin installation, double click the VI package file. There will be a version number at the end of the filename however, that can change as new releases become available. Open the folder and find the VI Package file pitsco_education_lib_tetrix_myrio_tools_ht. First robotics labview xbox download#After that has been done, download and unzip the file TETRIX_HT WRO VI s to a folder on your computer. Please reference the instructions and resources included with myrio for help on completing these items. You must first have installed LabVIEW and configured your myrio. 1 TETRIX myrio Programming Tools for LabVIEW Overview This document provides guidance on installation of the TETRIX myrio programming tools for LabVIEW, and a brief overview of each VI.
