Introduction
The AL5 series robotic arm is a four or five axis jointed arm-type robot driven by four to five servo motors. It uses a serial servo controller to control all motion.

End Effector
The end effector is a device or tool connected to the end of a robot arm. The Lynxmotion possesses a gripper.

Work Envelope
The work envelope is spherical, just like the Scorbot and all other jointed arm type robots.
Servos
The servos are electromechanical devices that use feedback to provide precise movement of the robot’s joints.

Servos: Wiring
The red and black wires provide power. The yellow wire sends a pulse from the controller to indicate which direction to turn and how far to go. http://www.lynxmotion.com/images
Servos: Operation
• The SSC-32 sends a pulse to the servo motor on the yellow wire. A pulse of 1.5msec moves the servo to its center position.
• A pulse of 1msec moves the servo 360° counterclockwise, and a 2 msec pulse moves the servo 360° clockwise.
• These values are approximate.
Servos: Operation
• The SSC-32 controller moves the servos. • The ArmControl software is the interface
that makes complex moves easier to perform.
SSC-32 Interface
The SSC-32 is a serial servo controller that provides the interface between the robot and the computer. It can be used to control up to 32 servos.
Outputs: Servos
Pins 0-7 are reserved for the robot’s servos.
Outputs
Pins 8-15 are reserved for outputs and can be used to send information to other equipment.
Inputs
Pins A-D are reserved for inputs and can be used to monitor switches and sensors.
Servo ConnectionsAlways check polarity when connections are made to the SSC-32 and never make connections while powered on.– Black servo wire goes to Ground– Red servo wire goes to VS1 pin– Yellow servo wire goes to PULSE pin
Startup Procedure
1. Plug USB Converter into computer’s USB port.
2. Reboot your computer.
3. Turn on the switch to the SSC-32.
4. Open ArmControl.
5. Once connection is established, turn on servos.
Shutdown Procedure
1. Turn off Power to the servos
2. Turn off power to the SSC-32
3. Close ArmControl
4. Unplug USB converter from computer
