01 / What We Fabricate
The Mechanical Structure Behind Robotics Performance
Robot frames and chassis locate payloads, drive modules, batteries, sensors, covers and service panels. We fabricate the structural sheet metal and weldment package around the OEM's released design, keeping functional interfaces measurable and repeatable.
Chassis Decks and Covers
Formed decks, base plates, removable covers and electronics bay panels with controlled fit and finish.
Sensor and Payload Brackets
LiDAR, camera, safety scanner, drive and payload brackets inspected from functional datums.
Production Subassemblies
Hardware-ready frame and panel kits packed by platform, revision and assembly sequence.
Our scope: the fabricated robotics frame, chassis and mechanical kit
The robotics OEM owns drives, motors, controls, batteries, software, sensors, safety validation and final robot compliance. DRAmetal manufactures the released sheet metal frames, covers, brackets and specified mechanical subassemblies.
02 / Robotics Fabrication Scope
Frames and Chassis for Automation Platforms
Use this page for a robot platform's primary welded or formed structure across automation cells, AMRs, service robots and equipment frames. For a mobile base-specific chassis, use Robot & AGV Chassis; for mixed brackets, covers and local housings, use Robotics Sheet Metal Parts.

04 / Manufacturing Process
From Prototype Frame Review to Repeat Production
01
Platform Review
Confirm robot type, payload, sensor interfaces, drive clearances, battery bay and service access.
02
DFM and Fixture Plan
Review bends, weld access, tolerances and fixture strategy around functional datums.
03
Prototype Build
Fabricate representative frames, brackets and covers and capture required design or process changes.
04
Welding and Forming Control
Use sequence, locators and inspections to protect critical mounting relationships.
05
Finish and Hardware
Apply coating or anodizing, install hardware and recheck interfaces affected by finish thickness.
06
Production Packout
Release controlled kits by robot platform, revision and assembly sequence.
05 / Why It Matters
Why Robotics Frames Need More Than Generic Fabrication
Robotics frames carry moving loads and locate sensors. Small changes in angle, stiffness or hole position can create navigation, vibration or assembly problems.
Sensor Alignment
LiDAR, camera and safety scanner mounts need formed-state geometry and stiff local support.
Weld Distortion
Frame welding can shift payload, drive and service interfaces unless fixtures and sequence are planned.
Weight and Stiffness
Material and rib strategy must balance payload capacity, vibration and platform mass.
Production Repeatability
Prototype hand fitting must be converted into measured datums, fixtures and inspection records.

09 / FAQ
Robotics Frame Fabrication FAQ
How is this different from the AGV chassis page?
The AGV chassis page focuses on mobile robot base structures. This page covers broader robotics frame fabrication, including welded equipment frames, sensor brackets, chassis decks, covers and production kits.
Can you control sensor mounting datums?
Yes, when the drawing defines measurable datums and tolerances. We can use fixtures, templates or formed-state inspection to protect sensor-facing surfaces and hole patterns.
Do you install motors, drives or sensors?
Normally the OEM or integrator installs drives, motors, batteries, sensors and controls. We manufacture the sheet metal structure with the correct mounting provisions and hardware.
Can you support prototype to pilot production?
Yes. We can fabricate prototypes, document changes, create first article checks and support pilot batches once the design is released.
