DOBOT CRAS Series Robotic Arm (SafeSkin)
| A-000000-08078
Price upon request
The DOBOT CRAS series includes 6-axis cobots designed to automate industrial tasks while improving safety in shared workspaces thanks to SafeSkin, a non-contact pre-detection technology that anticipates an obstacle approaching and triggers avoidance or a stop.

An “industrial” cobot series with SafeSkin: faster collaboration, safer shared spaces
- Collision pre-detection: SafeSkin detects obstacles before contact (detection range 5 to 15 cm depending on the installation area).
- High responsiveness: detection cycle 0.01 s and emergency stop execution time 0.1 s.
- More efficient collaboration: in shared spaces, SafeSkin enables collaborative operation up to 1 m/s (vs ~0.25 m/s typically), with efficiency gains up to x4.
- Conductive material detection: sensitive to various conductive materials (e.g., human body, metals, water/liquids).
- Recommended installation: on the front area of the arm, with recommended installation on J4, J5, J6.
- Wide & robust coverage: wearable silicone cover, protecting the front of the arm and able to “sense” 360° around the covered area.
- Fewer stops, better continuity: active avoidance when possible, otherwise fast stopping (aim: reduce collisions and unnecessary stops).
The DOBOT CRAS series is designed for automation in shared workspaces: thanks to SafeSkin (non-contact pre-detection), the cobot anticipates intrusions and reduces stops to make tasks safer and smoother.
Choosing the right model: CR3AS, CR5AS or CR10AS
The choice depends on payload (tool + part), reach, and available space.
- For compact workstations: CR3AS.
- For versatile use: CR5AS.
- For a larger working area: CR10AS.
| Model | CR3AS | CR5AS | CR10AS |
| Max payload | 3 kg | 5 kg | 10 kg |
| Reach | 620 mm | 900 mm | 1,300 mm |
| Repeatability | ±0.02 mm | ±0.02 mm | ±0.03 mm |
| Weight | 16.5 kg | 25 kg | 40 kg |
| Max linear speed | 2 m/s | 2 m/s | 2 m/s |
| Typical power | 120 W | 150 W | 350 W |
CRAS vs CRA: the difference is SafeSkin (non-contact pre-collision)
The CRAS series is based on the CRA cobots and adds SafeSkin to detect obstacles before contact, trigger avoidance maneuvers and/or a fast stop. The goal is to maintain good productivity in shared environments without excessive slowdowns or stops.
Applications and project types (shared environments, flexible production)
The CRAS series is relevant whenever a robot must work close to operators, in areas where interactions and intrusions are frequent: loading/unloading, assembly, bin picking, gluing, insertion, polishing, quality inspection, screwdriving, and transport.
Typical industries: consumer electronics/3C, automotive, semiconductors, healthcare, chemicals, retail (mixed human-machine environments).
Software ecosystem and integration
CRAS robots integrate into industrial cells through the Dobot ecosystem (graphical programming, guided teaching depending on the model, accessories and process integration). SafeSkin is designed to work without a vision sensor and relies on proximity/contact detection to activate safety strategies.
What information should you prepare for a quotation request?
Please specify: your budget (even if it’s an estimate), your project timeline (short term, awaiting funding, early study phase before the project, etc.), your address, and one sentence describing your project.

FAQ – DOBOT CRAS series
Is CRAS a different robot or an option?
CRAS refers to cobots equipped with SafeSkin for pre-collision detection (detection before contact), with very short reaction times.
What detection distance can be expected?
Effective range of 5 to 15 cm depending on the installation location.
Does SafeSkin replace a risk assessment?
No. It adds an extra safety layer (pre-collision), but speed, zones and operating scenarios must remain consistent with your risk assessment and environment.
Which model should you choose: CR3AS / CR5AS / CR10AS?
CR3AS for compact workstations and light parts, CR5AS for versatile use, CR10AS for a large working area.
The DOBOT CRAS series includes 6-axis cobots designed to automate industrial tasks while improving safety in shared workspaces thanks to SafeSkin, a non-contact pre-detection technology that anticipates an obstacle approaching and triggers avoidance or a stop.
