Simple Hand Gesture Recognition Based on Fuzzy Logic for Controlling Mobile Robot

Gesture recognition technology can be applied in a variety of plans. In this study, a simple hand gesture recognition has been applied to a mobile robot to make it easier for someone to operate. The mobile robot uses differential drive and it is equipped with a Wi-Fi device. The simple hand gesture sensor used in this study is ZX sensor. The sensor outputs are then processed by fuzzy logic control. The use of fuzzy logic in controlling robots makes changes in wheel speed when turning smooth. The response time of the wheel when turning based on testing is around 2-4 seconds with fuzzy logic control and less than 1 second with on-off control.
