	The Self-Balancing Robot control system consist two boards, Terasic DE10-Nano FPGA board and Motor Driver board (BAL board) as shown in Figure  2 -6. The FPGA on the DE10-Nano is responsible for all the functions of the balance and control system. The motor driver board receives the control signal from the de10-nano to control the motor rotation. There are also some sensors and communication devices on the motor driver board. These devices can provide the status data of the robot and external communication interface to FPGA.

	The Self-Balancing Robot equips a Cyclone SoC FPGA, which means that the ARM processor is embedded in the FPGA. Therefore, there are two processor options available to control the Robot. One is to use the ARM processor and the other is implement a NIOS II processor in the FPGA. The kit provides the factory code for both processor. To switch between these two processor modes, user need to select via the mode select switch(MSEL[4:0]).

DE10-Nano Kit and Motor Driver Board

The Self-Balancing Robot control system consist two boards, Terasic DE10-Nano FPGA board and Motor Driver board (BAL board) as shown in Figure 2 -6. The FPGA on the DE10-Nano is responsible for all the functions of the balance and control system. The motor driver board receives the control signal from the de10-nano to control the motor rotation. There are also some sensors and communication devices on the motor driver board. These devices can provide the status data of the robot and external communication interface to FPGA. For detailed hardware information, please refer to 03_Hardware_Manual.pdf which can be found in the CD package.

= Setup Elements =

This chapter will introduce the switches and buttons that can be set on the Self-Balancing Robot. It explains the meaning and function of the setting. == Configuration Mode Switches ==

The Self-Balancing Robot equips a Cyclone SoC FPGA, which means that the ARM processor is embedded in the FPGA. Therefore, there are two processor options available to control the Robot. One is to use the ARM processor and the other is implement a NIOS II processor in the FPGA. The kit provides the factory code for both processor. To switch between these two processor modes, user need to select via the mode select switch(MSEL[4:0]).

If user want to select ARM to control the robot, the MSEL[4:0] needs to switch to "01010" , as shown in Figure 3 -7. Thus, when the robot is power on, the FPGA will boot from the Micro SD card and run the Linux by ARM processor to control the robot.

When MSEL[4:0] is set to "10010", as shown in Figure 3 -8.The FPGA will boot from the configuration device(EPCS). Then, after FPGA is configured, the NIOS II processor will control the robot. For users who is beginners to learn FPGA, using NIOS II processor will be easier than deal with the ARM processor.

== Operation Mode Switches ==

Figure 3 -9shows the SW0 and SW1 on the DE10-Nano board, Table 3 -1describes the corresponding modes and functions when SW0 and SW1 are set to different positions.

SW[1:0] Setting	Robot mode and function	Description
00	Default mode (Bluetooth and IR mode)	The robot can be controlled by smartphone APP and IR remote control
10	Default mode and Obstacle Avoidance	The robot can be controlled by a smartphone’s APP and IR remote control, it implements the obstacle avoidance function
01	Object following and obstacle avoidance	The robot implements the object following and obstacle avoidance (In this mode, the robot will not be controlled by smartphone APP and IR remote control)
11	Debug mode	Only supports ARM version robot, the control program will stop running, users need to reboot the robot or run the program again to control the robot. Normally it is used to debug the robot.

LED name	Description
LED1	Indicates the power supply status to motor driver board
LED2	Indicates the motor driver board provides 5V power to the DE10-Nano board

LEDs on DE10-Nano Board

Figure 3 -11shows the 3.3V power LED, CONF_D LED and other LEDS on the DE10-Nano board, Table 3 -3describes the LEDs functions.

LED name	LED status	Description
3.3V power LED	Light On	Power the DE10-Nano board with 3.3V from the GPIO interface
CONF_D	Light On	DE10-Nano board Configuration done
LED7	Light On	Robot is keeping balanced status
LED6~5	0--Light On 1--Light off	00--robot is in default mode (Bluetooth & IR control) 01--robot is in default mode and implements obstacle avoidance function 10--robot implements object following function
LED4	Light On	Battery power supply voltage is lower than 10V
LED3	Light On	Robot is turning right
LED2	Light On	Robot is turning left
LED1	Light On	Robot is moving backward
LED0	Light On	Robot is moving forward

Note: When LED3~0 are all lit indicates the robot is in DEMO mode.= Basic Operations =

This chapter illustrates the basic operations on how to start the robot when users receive it. == Connect Power Port ==

Remove the red protective cap from the output plug of the battery power, as shown in Figure 4 -12.

Insert the output plug of battery power into the input port of the motor driver board, as shown in Figure 4 -13.

== Power on the Robot ==

Place the robot on the plane, keep it in a horizontal state, then set the power switch of the motor driver board to ON position, as shown in Figure 4 -14.

Keep a Balanced State

When the LED7 on the DE10-Nano board is lit, please release the robot, it will keep balance automatically, as shown in Figure 4 -15.

== Attitude Control ==

The robot can perform posture recognition in real time through the acceleration sensor and the gyroscope and achieve balance by controlling the motors and adjusting the posture. For example, pick up the robot, it will detect that its current state is not in a horizontal state, when the robot is placed on a horizontal plane, the robot will access its current balance status and adjust accordingly and keeping it in balanced state without any external help. If an external force causes the robot to tilt forward, the motors will quickly produce the forward motion torque to compensate for the angle of the tilt and maintain the balance of the robot. If an irregular object is placed on the robot, the robot body will maintain balance.= Advanced Features Demonstration =

Based on the DE10-Nano SoC FPGA platform, Terasic’s Self-Balancing Robot can implement attitude algorithm, perform motion control, and execute movements autonomously, such as moving forward, turning right & left, power monitoring, object following and obstacle avoidance. Line following and obstacle avoidance are described below. == Obstacle avoidance demonstrate ==

Once the ultrasonic module is assembled on the robot, object following and obstacle avoidance can be implemented with the module.

When the robot is in default mode and obstacle avoidance is on (SW[1:0] is on “10” position, as shown in Table 3 -1), if the ultrasonic sensor detects the obstacle is in front of the robot and the distance is within 10 cm, the robot will stop automatically, which will implement the obstacle avoidance function, as shown in Figure 5 -16.

When the robot is in object following and obstacle avoidance mode (SW[10] is on “01” position, as shown in Table 3 -1), and if the ultrasonic sensor detects the object is in front of the robot and the distance is within 10 cm, the robot will automatically move backward to avoiding object. When an object is in front of the ultrasonic module and moves slowly and the distance is within 10 cm~20 cm, the robot will continue to move along with the object, which will implement the object following function, as shown in Figure 5 -17.

Charging the battery

The robot is powered by a three-section of lithium battery (the specific parameters of the battery can be seen outside the battery package). When the power is less than 10V, the LED4 on DE10-Nano board will light up, indicating that the battery needs to be charged in time; and the APP will also show the battery power level. If the lithium battery starts charging after it is completely drained and is completely unable to supply power to the robot, it will take up to 2 hours the battery to be fully charged. The battery charging steps are as follows:

Power off the robot, pull out the power cable, and take the battery out of the robot’s onboard battery storage space, as shown in Figure 6 -33.

As shown in Figure 6 -34, connect the charger to battery connector.

As shown in Figure 6 -35, plug the charger into the AC 220V or 110V power outlets, after the power is fully charged, the LED on the charger will light up green, then unplug the charger.
