Congratulations on your purchase of the SR-RH8D Hand. This hand is the result of years' experience in hand design and use, and it aims at incorporating everything a robot builder needs: reliability^3, ease of use and compatibility with existing robot platforms in both hardware and software.

When unpacking, please check your package contents.

• 1x SR-RH8D Hand

• 2x SR-RH8D Hands

Note: The Bluetooth interface and Capacitive Pads, if ordered, are installed inside the unit. They will not be visible from the outside.

• 1x Power Supply 12V
• 1x USB to Serial converter cable. \\Typically, this will be a special 2-in-1 cable with miniaturized circuitry built inside the USB connector.
• 1x Power and Data Hub board
• 1x or 2x Long connection cable (depending on whether you ordered one unit or a pair or units)
• 2x Short connection cables

The Long and Short connection cables are similar and can be interchanged if the user needs. The Long cable is usually used to connect to the main unit but this is not mandatory; any of the cables can be used.

The hand is assembled by means of 8 screws located on the back (“wrist”) position. These screws are designed with common spacing in mind, being compatible with assembly on Robotis Dynamixel Pro Series (such as used in Thor-Mang).

Assembly screws are already pre-assembled (in green). Remove them, including the washers. Pay attention to NOT remove the screws in red or any other screws as they are structural to the hand assembly.

The wrist rotation has slightly over 180º of range. Therefore, for correct assembly, rotate central hub so that triangle in center part aligns with top triangle in outer shell. This corresponds to neutral angle. Wrist will rotate 90 degrees left and right from this position.

Use supplied M2.5x16mm screws to mount unit. Take care to notice that screws must enter the unit between 12mm and 16mm. This means supplied screws can be used with mounts up to 4mm thick. If thicker mount is to be used, please use longer screw accordingly.

After this step and without applying power, manually rotate unit to confirm assembly was performed correctly. Unit should turn around 180º total.

IMPORTANT:

When tightening screws do not push them in. Screws should be tightened by rotation only.

BEST PRACTICE: we suggest applying thread lock glue to the screws holding the hand. Use of the washers is recommended but not necessary, depending on the mount material

Complete the assembly by connecting a Dynamixel cable from the hand to the nearest interface (servo or PC adapter).
