RoboArm By Alaa Dwikat Mohammad tami Supervised by Dr. Samer Arandi Overview Mechanical part Sensors Communication Controller part Conclusion Content RoboArm 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) Overview Overview Mechanical part Sensors Communication Controller part Conclusion Content Mechanical part Material Design Motors Mechanical part We used PVC It’s very light can be easily clipped Material of structure Design 4-degree-of-freedom robotic arm 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 Generate pwm to control the angel/position 12 Motors Servo motors Overview Mechanical part Sensors Communication Controller part Conclusion Content Player hand act as a main controller of all mechanical part components. Two type of sensors are used: Flex Sensor. Accelerometer Sensor. Sensors 15 Accelerometer Sensor Sensors Accelerometer is a device that measure acceleration in one, two, or three orthogonal axes [8]. The ADXL345 is a low-power, 3-axis accelerometer modules with both I2C and SPI interfaces 16 Sensors Accelerometer Sensor Small and thin component. low power. Complete 3-axis 17 Flex Sensor Sensors It’s simply a variable resister that changes value depending on its bend 18 Overview Mechanical part Sensors Communication Controller part Conclusion Content Wireless XBee Communication 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. Communication Overview Mechanical part Sensors Communication Controller part Conclusion Content Sender Circuit Receiver circuit Controller part Controller part Overview Mechanical part Sensors Communication Controller part Conclusion Content We are able to simulate user hand movement by sending sensors data to the microcontroller that controls arm robot. Conclusion 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.
