Yaskawa Motoman
SIA20D
A slim, single 7-axis arm rated for 20 kg payload that can reorient its elbow without affecting hand position, taking up only one square foot of floorspace when straightened — suited to injection molding, machine tending and assembly in tight spaces.
Full specifications
Performance
How much it lifts, how far it reaches, how precisely it repeats.
- Payload
Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.
- 20 kg 44th pct in class
- Reach
Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.
- 1,498 mm 41th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.1 mm 4th pct in class
- Axes (DOF)
Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.
- 7
- Wrist torque
Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.
- 58.8 N·m 46th pct in class
- Wrist inertia
Allowable moment of inertia at the wrist — how much rotating mass it can swing without overload. Higher is more capable.
- 4 kg·m² 54th pct in class
Physical
Size, mass and how it mounts.
- Robot weight
Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.
- 120 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, wall, ceiling
Power & controller
Electrical supply and the control cabinet that drives it.
- Power rating
Rated supply capacity the installation must provide.
- 2.2 kVA
- Controller
The control cabinet / unit that runs the robot.
- DX100
Safety
Standards met and collaborative-operation capability.
- Collaborative
Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).
- No
Control & software
Programming, languages and ecosystem.
- Languages
Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).
- INFORM III
