00:58 — Custom design service for a 4-axis.
What we offer — end-to-end 4-axis robotic arm design
We provide complete engineering services for a 4-axis robotic arm design. From initial concept and CAD robot arm design to final assembly, we deliver:
Concept & feasibility: robot arm designs, movement analysis and payload sizing
CAD deliverables: 3D CAD models (STEP/IGES), 2D schematics (DWG/PDF), BOM and manufacturing notes
Control & electronics: robotic arm control design and wiring diagrams
End-effector integration: gripper selection and mounting, including robotic gripper options
Prototyping: robotic arm prototype, testing and iterative improvements
Full technical documentation: assembly drawings, test procedures, certificates
Deliverables you can expect
Every project includes a clear package of deliverables: printable 2D schematics, CAM-ready 3D design files, a mechanical drawing set, wiring schematics, and if required, source CAD files for CATIA / AutoCAD / SolidWorks / GrabCAD. We can prepare a custom folder of the design including STEP files for manufacturing partners.
Typical workflow
Requirements & payload analysis (designing robotic arm for payload, motion study)
Preliminary concept & CAD 3D modeling (robot arm 3D design)
Detail design & simulations (robotic arm detail design)
Prototyping & validation (robotic arm prototype)
Delivery of 2D schematics, 3D CAD models and full technical documentation
Design specifics & technical considerations
We cover engineering aspects across mechanical, electrical and controls domains: joint selection for a 4 dof robotic arm design, motor sizing for required torque, bearing/encoder specs, cable routing, and safety interlocks. We document all robot arm design parameters and provide simulation results for actuator selection and motion profiles.
Examples of design parameters
Degrees of freedom: 4 (3 revolute joints + wrist or prismatic option) — we have designed a robotic arm with 3 revolute joints and additional wrist stages.
Payload and reach calculations (we include detailed load & moment calculations)
Repeatability & tolerance stack-up analysis
Materials & finish — aluminum, steel or composite options
CAD platforms & file types
We deliver CAD files in common formats for manufacturing and collaboration: CATIA, SolidWorks, AutoCAD, GrabCAD exports and neutral STEP/IGES. If you require a native format (e.g., CAD design robot arm in CATIA or robot arm design AutoCAD), specify it during the requirements phase.
Pricing & how to buy
If you'd like to buy or order a custom design, send us your brief and required deliverables. Typical design cost ranges depend on complexity — small concept designs start from the low thousands, while full electromechanical detail design with prototypes ranges higher. We provide transparent quotes and milestone billing.

FAQs & design notes
Can you design a robot hand / gripper?
Yes — we design end-effectors and custom gripper integration for 4-Axis robotic arm systems. We adapt standard or custom grippers depending on payload and tooling.
Which CAD systems do you use?
We use CATIA, SolidWorks, AutoCAD and provide STEP/IGES exports for manufacturing partners. For 4-Axis robotic arm projects, we can also prepare ready files for GrabCAD repositories and collaborate via cloud platforms.
Do you produce control firmware?
Yes — our team handles 4-Axis robotic arm control design and integration with PLCs, real-time controllers and ROS when required.
Can you create an off-the-shelf kit to buy?
We provide both bespoke 4-Axis robotic arm designs and productized modules. Contact our sales team to discuss feasibility and delivery.
