Technical Highlights

Proactive Collision Prevention
SafeSkin employs Dobot’s proprietary pre-collision sensing technology, which detects obstacles within 10–20 cm and halts the robot before contact occurs.

Faster Speed Without Sacrificing Safety
While conventional cobots must reduce speeds to around 0.25 m/s in shared workspaces, SafeSkin allows collaborative operations at speeds of up to 1 m/s. This optimization increases efficiency by up to four times while maintaining worker safety.

Sensitive Detection of Diverse Conductive Materials|
SafeSkin is sensitive to various conductive materials, including human bodies, metals, water, etc. It is highly responsive to trigger safety protocols to prevent potential hazards.
