Dynamic hand gesture recognition using a stretchable multi-layer capacitive array, proximity sensing, and a SVM classifier

IROS 2021poster

Hand Gesture Recognition (HGR) has application in Human Machine Interfaces (HMIs), to control robots, games, and machines. Here we demonstrate a soft-matter multi-layer printed electronic circuit, that can be used to detect the human gesture without the need for physical contact, except for unlockin…

Water Based Magnification of Capacitive Proximity Sensors: Water Containers as Passive Human Detectors

IROS 2020poster

Sensors that detect human presence received an increasing attention due to the recent advances in smart homes, collaborative fabrication cells, and human robot interaction. These sensors can be used in collaborative robot cells and mobile robots, in order to increase the robot awareness about the pr…

Soft-matter sensor for proximity, tactile and pressure detection

IROS 2017poster

Efforts in soft-matter sensing with liquid metal (LM) have largely focused on pressure, strain, and bend sensing by measuring changes in capacitance or resistance of LM circuits embedded in a soft elastomer. Here, we show that LM electronics can be used to combine pressure sensing with proximity det…

State estimation and path following on curved and flat vertical surfaces with Omniclimber robots: Kinematics and control

IROS 2015poster

Omnidirectional wheels used on Omniclimber inspection robot and in other robots enable a holonomic drive and a good maneuverability. On the other hand, they have a poor wheel traction and suffer from vertical and horizontal vibration, decreasing the trajectory following accuracy of the robot. In thi…
