Open the green VS1 terminal blocks by

371

loosening each of the screws at the top. Connect the larger battery

372

wires to the VS terminals, ensuring there are no stray wires which may

373

create a short circuit. Leave the VL=VS jumper in place, as well as the

VS1=VS2 jumpers.

Connect the two servos to pins on the

388

SSC-32, with

389

the black wire being on the outside of the board. Clean up the wires

390

using wire ties, electrical tape or other means. The Lynxmotion 6V,

391

2800mAh battery is intended to fit snugly between the SES carrier and

392

the BotBoarduino. Connect the servo on the left side for pin 0 and the

393

servo on the right side to pin 1 on the SSC-32.

Step 16a. (SSC-32).

The SSC-32 can accept commands either via the

447

serial port, or via the Tx / Rx pins.

448

If you are using the SES complete kit, connect the Bluetooth Bee module

449

to the Bluetooth / RS232 adapter board. Connect

450

the + and - terminals fron underneath the board to the + and -

451

terminals on the SSC-32 (next ot letters A and B). For use with

452

FlowBotics Studio, connect the left motor to digital pin 1, and the

453

right motor to digital pin 0.

454

The VL=VS jumper must be removed as in the schematic below. A 9V

455

battery as well as the 6V battery need to be connected. Not every motor

456

is identical, so there may be a slight offset (for example 1550 rather

457

than 1500; 92 degrees instead of 90).

Step 16c (SSC-32U).

The SSC-32U

can accept commands either via the USB port, via the Tx / Rx pins or a

480

XBee type wireless module. If you are using the SES complete kit,

481

connect the Bluetooth Bee module

482

to the Xbee headers as shown below. For

483

use with FlowBotics Studio, connect the left motor to digital pin 1,

484

and the right motor to digital pin 0. Within FlowBotics, press the

485

Bluetooth button to change the default baud rate to match that of the

Bluetooth module.

Step 16b. (BotBoarduino).

502

Continuous rotation servos can be driven

503

using the servo library which comes with the Arduino software

504

(www.arduino.cc). A pulse of 1500us (90 degrees) stops the motors. Not

505

every motor is identical, so there may be a slight offset (for example

506

1550 rather than 1500; 92 degrees instead of 90).

17. (Optional PS2 for BotBoarduino)

525

IDownload and install the Arduino IDE from <a href="https://www.lynxmotion.com/images/html/www.arduino.cc">www.arduino.cc</a>.

526

In order to control the Rover wirelessly using a PS2 controller, you

527

will need to purchase RC-01 V2 as well as the EC-03 PS2 Receiver

528

Carrier and install them on the robot as shown in figure 17. Once you

529

have done this, connect the PS2 receiver to the BotBoarduino as shown

530

in figure 17. Sample code for controlling the rover using an optional Lynxmotion PS2 remote control can be found on <a href="https://github.com/Lynxmotion/Rovers/tree/master/Rover_2WD_PS2" target="_blank">Lynxmotion's Github</a>. The left servo is connected to digital pin 3 and the right servo is connected to digital pin 4.

531

532

533

Note: The 9V battery is OPTIONAL; the BotBoarduino's onboard regulator

534

needs a minimum of 5.1V to operate, so if you are using a 6V battery,

535

you can use it to power both VL and VS. However, if you are using a

536

battery below 5V, you will also need a 9V battery to power VL.

Download and install the Arduino IDE from <a href="https://www.lynxmotion.com/images/html/www.arduino.cc">www.arduino.cc</a>. The left servo is connected to digital pin 3 and the right servo is connected to digital pin 4.

565

In order to control the Rover from the Arduino IDE, you need to send

566

normal servo commands to digital pins 3 and 4. More information about

567

the servo library can be found on the Arduino website.
