Overview � Robo. Arm is a machine which allows the user to capture items (stuffed toys, balls ) that are placed in a round. � The player wears a special glove and moves his hand left – right, forward - backward and closes his fist in order to control wirelessly the moving arm that ends with a gripper.

Overview � Our project can be used to control a group of components coordinated together to complete a specific tasks. � Quarantine Environments (e. g. Chemical laboratories)

Mechanical part

Mechanical part � Material � Design � Motors

Material of structure � We used PVC � It’s very light � can be easily clipped

Design � 4 -degree-of-freedom robotic arm

Motors q Two types of motors used � DC motor � Servo motor

Motors DC used for rotating the structure

Motors Servo motors It’s an angular position controlled

Motors � Servo motors

Sensors q q Player hand act as a main controller of all mechanical part components. Two type of sensors are used: ØFlex Sensor. ØAccelerometer Sensor.

Sensors � Accelerometer Sensor

Sensors � Accelerometer Sensor

Sensors � Flex Sensor

Communication � Wireless XBee

Communication q � � � Wireless XBee Send results of sensors (located on the glove ) to microcontroller that control the mechanical part. Frequency 2. 4 GHz ( 16 channel) Data rate 250 Kbps Range 30 meters in door, and can reach up to 90 m outdoor. Point-to-point, point-to-multipoint and peer-to-peer topologies supported.

Conclusion � We are able to simulate user hand movement by sending sensors data to the microcontroller that controls arm robot.

Future Work � Provide an additional degree of freedom by add more axes. � Using another module for wireless connection, so that the cost be cheap � Finally we can design five-fingers hand instead of a gripper.
