What makes it work
DOBOT CR5AS
5 kg SafeSkin Collaborative Robot with 1096 mm Reach, 5-Level Collision Detection & Drag-to-Teach Interaction Panel — Built for Intelligent Human-Machine Collaboration
Smarter Collaboration Starts Here
The DOBOT CR5AS is a 5 kg payload collaborative robot built for environments where precision, safety, and ease of deployment are equally critical. With a maximum reach of 1096 mm and a working radius of 900 mm, the CR5AS covers a significantly wider workspace than compact-class cobots while retaining a manageable footprint of just 25 kg — making it straightforward to mount, relocate, or integrate onto mobile platforms.
What distinguishes the CR5AS within the CRAS series is its intelligent interaction panel — a dedicated interface that provides instant access to drag-to-teach programming, dramatically lowering the barrier for operators to define new motion paths without specialist coding. Combined with 5 adjustable collision detection sensitivity levels, teams can tune the safety response precisely to match the task and proximity requirements of their specific production cell.
Available in AC Edition (Standard) for fixed-cell installations and DC Edition (Mobile) for cart or AGV-mounted deployment, the CR5AS is engineered to grow with your automation requirements across a wide range of light to medium industrial applications.
At a Glance
Four Pillars of Performance
Performance
2 m/s linear speed with joint speeds up to 223°/s on J3–J6 delivers fast, efficient cycle times across high-throughput production tasks.
Safety
SafeSkin proximity and contact sensing with 5-level adjustable collision detection ensures the robot stops before any harmful contact occurs.
Scalability
AC and DC editions plus a broad I/O interface allow the CR5AS to scale from a single fixed-cell deployment to fleet-wide mobile automation.
Flexibility
Drag-to-teach via the intelligent interaction panel and TCP/IP, Modbus, Wi-Fi connectivity make reprogramming and integration fast and accessible.
Built for the Way You Work
SafeSkin — Sensing Before Contact
The SafeSkin sensor system wraps the CR5AS's distal joints (J4, J5, J6 recommended) in a proximity and contact detection layer that monitors the surrounding space continuously at a 0.01 s sensing cycle. The moment a human body, metallic object, or liquid enters the 5–15 cm detection zone, the robot triggers an emergency stop within 0.1 seconds — before any physical collision. This pre-collision architecture allows operators and robots to share the same workspace genuinely, removing the need for full safety fencing in many deployment scenarios.
SafeSkin Sensor Specs
- Sense Type: Proximity and contact
- Sensing Targets: Human bodies, metals, liquids
- Installation: J4, J5, J6 recommended
- Effective Range: 5 ~ 15 cm
- Sensing Cycle: 0.01 s
- Emergency Stop: 0.1 s
Drag-to-Teach & 5-Level Collision Detection
The CR5AS ships with an intelligent interaction panel that puts drag-to-teach programming at an operator's fingertips. Rather than requiring a programmer to write motion paths from scratch, any trained operator can physically guide the arm through a desired trajectory and have the robot learn it immediately. This capability dramatically compresses changeover time in mixed-product environments. Complementing this, five independently adjustable levels of collision detection sensitivity mean safety behaviour can be precisely calibrated — from high-sensitivity collaborative zones to lower-sensitivity positions where contact forces are intentionally higher during tooling operations.
Ease of Programming
The integrated interaction panel offers direct access to drag-to-teach mode — no laptop or external teach pendant required for basic path programming. Combined with DOBOT's software ecosystem, advanced motion sequences are equally accessible for more complex automation workflows.
Six-Axis Freedom with Industrial-Grade Precision
All six joints of the CR5AS deliver wide angular freedom: J1, J2, J4, J5, and J6 rotate ±360°, while J3 covers ±160° — enabling the arm to navigate complex, articulated paths without repositioning its base. A repeatability of ±0.02 mm holds part placement to sub-millimetre tolerances across millions of repeated cycles. The rated voltage of 48V DC and 150W power consumption keep operating costs low, while the aluminium alloy and ABS plastic construction ensures the 25 kg arm remains robust under continuous-duty industrial use across temperatures from 0°C to 50°C.

Open I/O and Triple-Protocol Connectivity
The CR5AS controller provides 16 DI and 16 DO/DI digital channels, 2 AI/AO analogue channels, and 1 ABZ incremental encoder input — offering substantial headroom for connecting sensors, fixtures, and custom end-of-arm tooling. The end-effector interface supplies 2 DI/DO/AI ports over RS485 for direct peripheral control at the tool. Network communication via TCP/IP, Modbus, and Wi-Fi covers integration with PLCs, SCADA systems, ERP platforms, and vision systems. The DC Mobile Edition further extends this by enabling the entire robot to operate from a battery-fed mobile platform, making truly flexible manufacturing cells a practical reality.

DOBOT CR5AS — SafeSkin Collaborative Robot Series Overview
Frequently Asked Questions
The CR5AS offers five independently adjustable sensitivity levels for collision detection. At higher sensitivity levels, the robot will stop upon detecting very light contact forces — suitable for cells where human operators work in very close proximity. At lower sensitivity settings, higher contact forces are permitted, which is appropriate for tooling operations or tasks where the robot intentionally applies force. Operators can select the level that best matches each application's safety and performance requirements.
Drag-to-teach allows an operator to physically move the robot arm through a desired motion path while the controller records each position. The intelligent interaction panel on the CR5AS provides direct, on-robot access to this mode — no laptop or external programming device is required for basic path definition. Once a path is recorded, it can be saved and replayed, making changeovers and new task setup significantly faster for non-specialist staff.
The AC Edition (Standard) is designed for fixed-cell deployment connected to mains power. The DC Edition (Mobile) is configured to run from a DC power source, making it compatible with autonomous mobile robot platforms and cobot trolleys. Both editions share identical robot arm specifications — the difference is purely in the power input and intended deployment style.
The CR5AS supports a maximum payload of 5 kg and achieves a maximum reach of 1096 mm, with a working radius of 900 mm. This combination suits a broad range of light to medium industrial tasks including assembly, gluing, bin picking, and loading/unloading operations where a longer arm with moderate payload capacity is required.
The CR5AS controller supports TCP/IP, Modbus, and Wi-Fi for network communication, and the end-effector interface communicates via RS485. The controller provides 16 DI, 16 DO/DI, and 2 AI/AO channels, along with 1 ABZ incremental encoder input. The end-effector interface adds 2 DI/DO/AI channels. This I/O complement supports integration with PLCs, vision systems, conveyor controllers, and most standard industrial peripherals.
