Integrated Controller
Integrated Controller
The controller is integrated into the robot body — no separate external control box needed — minimizing installation footprint and simplifying system setup. Without an external control panel, wiring is cleaner and installation/maintenance is easier.
Works Well With
Can be used together with the ROHand robot hand.
RM Series vs ECO Series
| RM Series | ECO Series | |
|---|---|---|
| Positioning | Premium cobot | Economical cobot |
| Main Target | AI robots, service robots, R&D, industrial automation | Manufacturing automation, education, research |
| Weight | ~7.2kg | ~7.8kg |
| Character | Ultra-lightweight, ideal for mobile AI platforms | Cost-effective, high safety, ideal for production lines |
| Brake | J1-3 hard / J4-6 soft | All joints hard brake |
RM Series
- •Ultra-lightweight design (~7.2kg)
- •Extensibility-focused for AI, vision, service robots
- •Ideal for mobile robot (AMR) and humanoid platforms
- •Soft brakes on some joints reduce weight and improve agility
- •Internal wiring support — routes end-effector cables (vision cameras, grippers) inside the arm
ECO Series
- •Cost-effective economical cobot
- •Mechanical (hard) brakes on all joints
- •Holds posture reliably during power loss or emergency stop
- •Optimized for production automation and industrial sites
- •Economical composite design — combines aluminum and engineering plastic
See the ECO 62/63/65 page for ECO series details.
