4 Turning the Device On/Off In order to turn the device ON/OFF, there is a toggle switch on the bottom of the metal battery mount towards the bottom of the stander. See Figure 2 below. Figure 2 ON/OFF Switch Charging the Battery To charge the battery, disconnect the black and red connector from the stander and plug the battery connectors into the corresponding plugs on the charger. Plug the charger into the wall. When the charger is plugged in, the power light will turn green. While the battery is charging the Charging light on the charger will turn red until it is fully charged. Once the battery is fully charged, the Ready light will illuminate. It takes approximately 4 hours for the battery to fully charge, but leaving the battery on the charger for longer will not hurt it. 3

5 Adjusting the Height of the Tray The height of the tray can be easily adjusted. First, make sure that any objects are not in the way of the channel system that runs up and down the middle of the stander. To loosen the tray assembly, loosen the two knobs on each side of the tray assembly for a total of four knobs. This will allow the tray assembly slide up and down on the main channel system of the stander. Slide the tray to the desired height and then tighten the four knobs so that the tray is secure. See Figure 3 below. Figure 3 4

6 Adjusting the Horizontal Position of the Tray To adjust the horizontal position of the tray, there are three knobs on the underside of the tray that need to be loosened. Two of the knobs are located in front of the main channel of the stander and the third knob is located on the other side of the tray on the underside. First, loosen all three of these knobs slightly and slide the tray to the desired position. Once the tray is in the desired position, retighten the three knobs to secure the tray. See Figure 4 below. Figure 4 5

7 Driving the Stander Driving Modes The stander has 2 modes, Toggle Mode and Press-and-Hold Mode. Toggle Mode-Toggle mode allows the stander to be driven without having to hold down the buttons to move. When a button is pressed and released, the stander will move in that direction until either the same button is pressed again or the stop button is pressed in which the stander will stop. Switch the mode toggle switch to TOGGLE to operate the stander in this mode. Press-and-Hold Mode- Press-and-Hold mode allows the stander to be driven only while a button is pressed. Once a button is released, the stander stops moving. Switch the mode toggle switch to HOLD to operate the stander in this mode. Changing Modes - To change modes, there is a toggle switch on the side of the board housing underneath the tray of the stander. See Figure 5 below Stander Mode Switch Figure 5 6

When the bumper is depressed, the only motion allowed by the stander is backwards, backwards + left, and backwards + right. Adjusting the Speed The speed of the stander is adjustable to accommodate different users. The knob is located underneath the tray on the board housing. Turn the knob clockwise to increase the speed, or counterclockwise to decrease it. The knob can also be switched to an off position by turning it counterclockwise until a click is heard. This feature disables the stander from moving regardless of button presses on the stander or remote. This allows the buttons to be moved, or a child to enter the stander safely without having to turn it off completely. See Figure 6 below. 8

11 Using the Remote Control The remote control can be activated by plugging the attached USB cable into the port found on the housing underneath the stander tray (See Figure 6 above). To turn on the remote control, flip the ON/OFF toggle switch to the ON position. There is also a toggle switch on the remote for Full Control/Assistive Mode. See Figure 7 below. Override Mode The Override Mode allows the trainer to have full override control of the stander. This would be useful for getting the user used to the feel of moving in the stander. To use Override Mode, first switch the remote control ON and make sure that the smaller toggle switch is switched to Override. The remote control can now be used to fully control the movement of the stander. Assistive Mode The Assistive Mode allows for the trainer to have corrective control over the stander. This mode does not allow the trainer full control using the remote control, but allows for the trainer to stop the stander or change directions if they realize that the user is running off course. To use Assistive Mode, first switch the remote control ON and make sure that the smaller toggle switch is switched to Assist. The remote control can now be used to assist the user in the stander in learning how to control and steer it. Notes ON/OFF Switch Mode Switch When the stander is in toggle mode, the remote control will not function in assistive mode. This is a safety feature which ensures the stander behaves as expected for all inputs. In override mode, the remote control will function as press and hold, regardless of the state of the toggle switch located on the stander. Figure 7 10

12 Editing and Modifying the Stander Board Program System Requirements Windows 7 or higher operating system Code Composer, which is a free program through TI but a trial version can be downloaded at ti.com USB Port USB A-male to USB-Mini B Male cable Modifying the code and flashing the program to the board. Users are not recommended to modify the code. For reference, the code is contained on EDGE and can be accessed via our SVN repository url: Modification of code requires Code Composer Studio V5.3, and StellarisWare for the LM4F232, both available fromwww.ti.com. Additionally, the user must install Subversion, available at Installation instructions are available online at both of these websites. Loading the application to the board requires the LM Flash Programmer. Download this utility from and open it. Under the configuration tab, look for the section named "Quick Set." Open the drop down and select LM4F232 Evaluation Board. Then select the "Program" tab. Under the heading "Select a.bin file", click browse and select the.bin file which was either built by you or downloaded from EDGE. Ensure "Erase Entire Flash" is selected and click the program button. The board is now programmed and will run the original application on startup. Obtaining the software source Code for the stander software can be obtained in its original from the SVN address above. Additionally, it can be obtained in PDF format at The software is separated into two subfolders, one for the stander board and one for the remote control board. 11

13 The bulk of the software is contained in main.c with some initialization and specialized functions contained in other files. System Requirements for Development Software From our testing, the LM Flash Program works on both windows 7 and windows 8. Windows XP is untested. Otherwise, the only requirement is a USB Port and a USB A-Male to USB-Mini B Male cable. 12
