# Part Organisation > Sort your Asimov 1 kit by module and keep track of the parts and hardware you have checked. - Page: https://docs.menlo.ai/asimov/1/build/assembly-preparations - Section: Asimov › Asimov 1 › Assemble Asimov 1 › Preparation When your kit arrives, check that all the parts are there before you start building. Work through each module checklist below to confirm you have everything you need to assemble your Asimov. As you go, inspect each part for any damage from shipping. If anything is missing or damaged, contact us as soon as possible, within the warranty period, and we'll send you a replacement. ## Sort parts by module Every manufactured part number starts with its module number. Sort the parts into one group per module, from 100 to 700, as shown below: | Number | Module | | - | - | | 100 | Torso | | 200 | Pelvis | | 300 | Right arm | | 400 | Left arm | | 500 | Right leg | | 600 | Left leg | | 700 | Head | ![Wrapped parts sorted into labelled module groups: 100 Torso, 200 Pelvis, 300 Right Arm, 400 Left Arm, 500 Right Leg, 600 Left Leg and 700 Head, with the actuators, cables and hardware set aside](https://docs.menlo.ai/manual/v1/images/part-organisation/parts-sorted-by-module.webp) > [!NOTE] > > **Matching parts may share a bag** > > Parts of the same type and design for different modules are sometimes packed in the same bag. For example, `ASV1_600_37C` (left foot) and `ASV1_500_37C` (right foot) come together. Take only the part for the module you are counting, and set the other aside with the module it belongs to, to count when you get there. > [!NOTE] > > **Some parts arrive bolted together** > > To protect them in transit and save packing space, some parts, such as the head and body covers, may already be bolted onto other parts. Unscrew them so you can count each part separately, and keep the bolts with that module's hardware: they are counted in the checklist and used again during assembly. > > ![Torso and head parts shipped in bubble wrap with covers already bolted on](https://docs.menlo.ai/manual/v1/images/part-organisation/parts-shipped-bolted-together.webp) ## Cable naming Cable names list the length first, followed by the connector type and purpose where needed, for example 1000 mm XT30-Male to XT30-Female power cable or 200 mm double-ended XT30 (2+2) cable. Single-ended cables have a connector at one end; double-ended cables have connectors at both ends. ![A double-ended cable with a connector at each end (top) and a single-ended cable with bare wire ends (bottom)](https://docs.menlo.ai/manual/v1/images/part-organisation/single-and-double-ended-cables.webp) Actuator cables use XT30 (2+2) connectors, distinct from XT30 power-only connectors. ![An XT30 (2+2) connector with 2 power barrels and 2 signal pins (left) next to power-only XT30 connectors with 2 power contacts and no signal pins (right)](https://docs.menlo.ai/manual/v1/images/part-organisation/xt30-vs-xt30-2plus2.webp) ## Actuator Type Asimov uses 5 types of actuator. Use the previews below to tell them apart; drag a model to rotate it. We recommend you to sort out actuator by type first as shown below, so it is easier to find them later on. > [!WARNING] > > **Do this now: label each actuator with its ID** > > While you sort out the actuator below, stick a piece of masking tape on each actuator and write its ID on it. This makes it much easier to match each actuator to its ID when you [assign actuator IDs](https://docs.menlo.ai/asimov/1/build/assembly-preparations/assign-actuator-ids.md). There should be a total of 25 actuators. When you sort them by type, remember to use a masking tape and write the ID on the actuator according to the ID list we given below in the 3D visualization. Each actuator should only carry one ID and vice versa, don't assign more than one actuator with the same ID. ![The five actuator types side by side, from left to right: EC-A5013-H17-100, EC-A3814-H14-107, EC-A4315-P2-36, EC-A4310-P2-36 and EC-A6416-P2-25](https://docs.menlo.ai/manual/v1/images/part-organisation/actuator-types.webp) ![Actuators laid out with their IDs handwritten on masking tape stuck to the back of each one](https://docs.menlo.ai/manual/v1/images/part-organisation/actuator-id-labels.webp) From left to right: **EC-A5013-H17-100**, **EC-A3814-H14-107**, **EC-A4315-P2-36**, **EC-A4310-P2-36** and **EC-A6416-P2-25**. The 3D previews below follow the same order. | Actuator model | Count | IDs and joints | | - | -: | - | | EC-A5013-H17-100 | 4 | ID 2: Left Hip Roll; ID 8: Right Hip Roll; ID 13: Left Shoulder Pitch; ID 18: Right Shoulder Pitch | | EC-A3814-H14-107 | 4 | ID 3: Left Hip Yaw; ID 9: Right Hip Yaw; ID 15: Left Shoulder Yaw; ID 20: Right Shoulder Yaw | | EC-A4315-P2-36 | 4 | ID 4: Left Knee; ID 10: Right Knee; ID 14: Left Shoulder Roll; ID 19: Right Shoulder Roll | | EC-A4310-P2-36 | 10 | ID 5: Left Ankle A; ID 6: Left Ankle B; ID 11: Right Ankle A; ID 12: Right Ankle B; ID 16: Left Elbow; ID 17: Left Wrist; ID 21: Right Elbow; ID 22: Right Wrist; ID 24: Neck Yaw; ID 25: Neck Pitch | | EC-A6416-P2-25 | 3 | ID 1: Left Hip Pitch; ID 7: Right Hip Pitch; ID 23: Waist Yaw | Module checklists, in order: 1.
