Maker manipulates a robotic arm with pressure-based hand gestures on the Sensel Morph. 


Ray Kampmeier recently finished a project that enabled him to manipulate a robotic arm using force-sensitive, five-finger hand gestures. To accomplish this, the self-proclaimed hobbyist employed a MeArm, an Arduino Uno (ATmega328), four servo motors, and a servo shield to control the mechanism.

Sensel’s soon-to-be-released touch interface — theMorph — is used to command the robotic arm in four different ways: force down, rotation, pinch and forward/backward. For example, placing five contact points down and twisting the wrist will rotate the base, applying pressure on four fingertips will raise and lower the arm, while moving along its XY axes will extend and retract it. What’s more, Kampmeier reveals that pinching all five fingertips together on the center of the touchpad will cause its attached claw to close.
