Tools Required - Lynxmotion AL5D-PLTW Manual

Note: We include a variety of additional parts which you will not use in the construction of the
arm. This is because the AL5D-PLTW is nevertheless part of a modular building system, and
parts / kits which make up the arm are also used in other kits.

Tools Required

Several standard tools are needed for the assembly of the arm, most notably:
● 3-30 Hex wrench suitable for the 4-40 screws (included)
● Phillips head screwdriver
● Small pan head screwdriver (for SSC-32U screw terminals)
● Wrench (for 2-56 nuts)
● 400 grit sandpaper (optional)
● Silicon based oil (optional)
Mechanics
The aluminum robotic arm is made using the Lynxmotion Servo Erector Set components for the
ultimate in flexibility and expandability. The kit consists of aluminum brackets, aluminum tubing,
custom injection molded components, and precision laser-cut Lexan components.
Dimensions
● Shoulder to elbow: 5.75"
● Elbow to wrist: 7.375"
● Wrist to tip of gripper: 3.375"
● Height (arm packed): approx. 7.25"
● Height (reaching up): approx. 19.00"
● Median forward reach: approx. 10.25"
● Gripper opening: 1.25"
● Weight: 31oz
● Range of motion per axis: 180 degrees
● Medium duty wrist rotate ads 1"
Load Capacity
The load capacity of the arm is based on multiple factors:
● Operating voltage: RC servos can accept between 4.8V to 6V
● Distance from the base: This factor is critical since the farther the object is from the
base, the more energy will be required to hold it against gravity
● Length of time the object is held: The longer the object is held against gravity, the more
the servos will heat up.
At median reach (elbow at 90 degrees), the arm can support up to 10 oz. As the arm is
extended, it will support a bit less, and as it is retracted, it can support a bit more.
