Researchers at TU Delft have developed a drone that can perch on branches using tactile sensors rather than relying solely on cameras. [^1]

Researchers at the Netherlands' TU Delft developed a drone equipped with a three-fingered grasping arm and nine touch sensors to enable safe perching on tree branches. [^2]

Once securely attached to a branch, the drone can shut down its motors to reduce noise and conserve battery power. [^3]

The drone uses a three-fingered robotic hand with soft capacitive sensors to detect branches through physical contact and adjust its position before gripping. [^4]

Tests revealed that the tactile approach allows the drone to land successfully even when visual assessments of the branch are incorrect. [^5]

The drone's grasping arm uses nine sensors made of copper electrodes embedded in silicone to detect the position and orientation of branches. [^6]

The system requires all three fingers to make secure contact before the drone fully closes the arm and shuts off its motor. [^7]

The control architecture is organized as a sequence of states including takeoff, searching, touch detection, approach, positioning, rotation, finalization, perching, and abort. [^8]
