Assembly Steps
This section is split by robot module so builders can follow the assembly flow in smaller chunks.
1. Assembly Order
Use the pages in this order:
2. Assembly Notes and Convention
- Steps that require thread locker are marked with a red thread-locker icon.
- Install each motor in the correct joint. Check the motor ID image here.
- Arm and leg assembly steps show the left side only; repeat them as a mirrored build for the right side.
- Follow the assembly order exactly to avoid fitment issues. Some parts, such as nuts, must be installed before later fasteners.
- Before final assembly, check alignment, part seating, and thread condition. If a screw does not turn smoothly by hand, stop and fix the issue first. Apply thread locker only when specified, and only after test-fitting.
- Review the wiring plan before assembly. Some cables must be routed before connectors, covers, or structural parts are installed.
- Screw callouts show quantity and specification, for example
4 × M4×12 flat head screws. - Motor callouts show motor type and motor ID, for example
EC-A4310-P2-36 (ID: 16/21), where16is the left-side motor ID and21is the mirrored right-side motor ID. - If you already installed the heat-set inserts during pre-assembly, you can skip the insert installation steps. Otherwise, follow the inserts steps to install them.
3. Tips for Assembly
Before mechanical assembly, open the box and sort the parts by module. Group screws, bolts, wires, connectors, motors, batteries, and electronics separately so the build sequence is easier to follow.
Before proceeding, confirm the following:
- all required structural parts are present
- fasteners are present and matched to the expected sizes
- motors are present and grouped by expected installation location
- the required tools are prepared
- the motion control board is ready
- the batteries are set up and charged
- wires and connectors are ready for routing and termination
4. Safety
Treat Asimov 1 as powered electromechanical hardware, not as a toy.
Before working on the robot, make sure you have:
- a stable workspace with room to support or suspend the robot safely
- a plan for power isolation and emergency shutdown
- basic electrical test tools such as a multimeter
- a controlled bring-up process for motors, wiring, and motion tests
During assembly and operation:
- Keep the robot unpowered and disconnect batteries or external power sources during mechanical work.
- Support heavy subassemblies properly while fastening or aligning them.
- Keep an emergency stop within immediate reach when operating the robot.
Do not attempt first power-on, homing, or motion tests casually. Early mistakes in wiring, joint direction, or configuration can damage components or create unsafe motion.
Safety first
Initial bring-up and locomotion tests should only be done in a controlled setup with the robot restrained, supported, or otherwise prevented from falling unexpectedly.
Battery Safety
Use only the specified lithium-ion battery pack and the recommended charger. For full battery specifications, see Battery.
Critical Operating Limits
Do not exceed the following limits:
| Parameter | Limit |
|---|---|
| Maximum charge voltage | 54.6 V |
| Maximum charge current | 15 A |
| Maximum discharge current | 31.5 A |
| Minimum discharge voltage | 35.75 V |
| Charging temperature | 0°C to 45°C |
| Discharging temperature | -20°C to 60°C |
Handling Precautions
Do not reverse polarity, short-circuit the terminals, or expose the battery to water, fire, direct heat, or high-temperature environments.
Do not pierce, crush, strike, disassemble, modify, or directly solder the battery terminals.
Do not store or transport the battery with metal objects that may contact the terminals.
Stop Use Immediately If
Stop using the battery if it shows odor, excessive heat, leakage, smoke, deformation, discoloration, or visible damage.
Storage
Store the battery between 45.5 V and 48.1 V. Recharge periodically during long-term storage to prevent over-discharge.
