Corrections to assembly video:
Step 12: Uses 4x 3/8” long Pan Head screws
Step 17: Uses 3/8” Clamping hub instead of set screw hub
Step 20: Uses ” long 5-40 Pan Head screws
Please note that many arm configurations are possible. Before starting the assembly, lay out all
the parts to ensure nothing is missing. Follow the assembly video to make the default
configuration.
Alternative designs can be obtained by changing the configuration of the joints. The image
below shows two elbow joint configurations by three elbow to shoulder connection
configurations. The kit also comes with an alternative tube length which can be used to
configure the shoulder to elbow to the shoulder (leaving three other tube lengths available for
the elbow to wrist joint). There are over 100 different configurations are possible with this kit.
Because of the multiple configurations, we suggest using the set screw collars and hub spacers
as spacers in order to prevent the frame from interfering with the servos. You are welcome to
devise your own assembly based on the configuration you desire and several spare parts have
been included in the kit.
