LUKE Arm System Batteries and Holster There are two battery types used to power the arm. Which battery type is used depends on your arm type and how your prosthetist configured the power to the arm. The two batteries are:...
Chapter 1: LUKE Arm System External Battery This battery, see Figure 3, is normally worn on a belt or in a pocket and is used in one of two ways: • In SC and HC arms, with an internal battery, it may be used to supplement power to the arm.
LUKE Arm System Figure 4. External Battery Holster Battery Holster with ON/OFF button Battery Holster without ON/OFF button Battery Chargers and Charging Dock There are three components used for charging the batteries: a charging pad, an AC Adapter, and a charging dock. The AC Adapter is used with the charging dock to charge the external battery.
Chapter 1: LUKE Arm System Charging Pad A wireless charging pad is provided in order to charge the IMU battery. Figure 5 shows the charging pad. Figure 5. Charging Pad for IMU Battery Charging Pad AC Adapter The AC Adapter is used with the external battery charging dock and to directly charge the internal battery within the arm.
LUKE Arm System Charging Dock The charging dock is used to charge the external battery. The charging dock has two slots allowing you to charge two batteries at once and is powered by the AC Adapter. When charging the battery you should remove the battery from its holster and place it in the charging dock.
Chapter 1: LUKE Arm System ACI (Arm Control Interface) Module The ACI Module, see Figure 8, receives signals from user inputs (e.g., surface EMG electrodes and pressure transducers) and sends them to the MAC which in turn controls the arm. The ACI Module provides four user inputs and connects to the arm.
LUKE Arm System Input and Output Control Devices The arm uses several input devices and a single output device to control the arm. The following sections describe these devices. IMUs (Inertial Measurement Units) IMUs are placed on top of your shoes and command motion or grip selection by having you tilt your foot.
User Controls and Wrist Display IMU LED Status The IMU LED shows the functions of the IMU. Pressing the display button for less than one second causes the IMU battery to blink showing the charge level. Table 8 describes the functions of the IMU LEDs. Table 8.

The first and foremost task in fitting, setting up, and configuring the arm is to meet with the client and determine their needs as they relate to the LUKE arm. As each client is different, you need to work with them to determine the appropriate arm configuration and system components that best fit them.
Indications For Use The LUKE arm system consists of a prosthetic arm and accessories which are used by a certified prosthetist to create a full upper extremity prosthesis indicated for individuals, age 18 years and older, who have partial or full upper limb amputations or congenital defects.
One LUKE arm system may be used at a time by an individual. For each arm that is to be fit on a client Mobius Bionics offers all the materials, aside from 3rd party supplied input sensors, to configure the arm system. Materials that are typically used to fabricate sockets and fit conventional prosthetics are not supplied by Mobius Bionics.
Chapter 1: Overview Arm Configurations The arm is available in the three configurations listed below and shown in Figure Once you have determined which arm configuration best fits your client’s needs, you need to specify if the arm is for the right or left side and the proper length as well as which battery type will power the arm.

User Inputs/Outputs and the Control Scheme Prior to setting up and configuring the arm you need to determine which types of user inputs the client can and will use to control the arm. To determine this control scheme, you and the client need to decide which types of inputs the client can physically operate in order to manage arm controls.
Chapter 3: User Inputs/Outputs and the Control Scheme User Inputs Listed below are the user inputs used to control the arm. Following the list is a description of each of the inputs, a description of how they are used, and any restrictions when using the inputs.
User Inputs Places Used Inertial Measurement Units (IMUs) are installed on top of client’s shoes using a shoe clip or custom fabricated strap or pocket. For detailed information on installing and setting up the IMUs see Chapter 8, “Installing IMUs”. Arm Controls IMUs are used to control arm motion and certain switching functions other than mode select.
Installing IMUs Once the ACI Modules have been installed and connected you can then install the IMUs. The IMUs can be installed on a client's shoe or lower appendage using either the shoe clips or an alternate means such as custom straps or pockets in the shoe. There are two steps to install the IMUs on a shoe: attaching the shoe clip to the client’s shoe and attaching the IMU to the shoe clip.
