Скачать или смотреть Tool position control: Encoder, Vision or RTLS? | Ansomat Tool Positioning Demo

In this video we explore the three major methods for tool-position control in modern assembly — and how each integrates with the Ansomat Operator Guidance System to guarantee precise, error-proof fastening.
🔧 1) Reaction arm with encoders

A mechanical reaction arm attached to the tightening tool uses encoders (rotary or linear) to record the tool’s exact position and orientation. This approach tracks the x, y, z coordinates and angle in real time, ensuring the correct bolt location and tightening sequence — and absorbs reaction torque during fastening. Ideal for fixed stations with repetitive tightening tasks.

📷 2) Machine vision tool position tracking

Using cameras and intelligent vision software, the system visually monitors the tool and assembly area before and during tightening. The tool’s position is validated by the vision system, which ensures the right bolt and orientation before the tool is allowed to actuate. This non-contact method also offers image-based traceability and supports visual quality checks.

📍 3) RTLS (Real-Time Location System) Tracking

RTLS uses tags on tools (or on operators) and reference anchors to continuously track the tool’s 3D position in space, regardless of orientation or operator handedness. This provides full spatial tracking across single or multiple workstations, suitable for flexible, dynamic, or large-area production layouts. Accuracy is within a few millimetres, offering reliable position control even where vision or mechanical arms reach their limits.
