Abstract

Communication protocol on OSI Layer standardization, divided into several layers among them is data link layer. This layer divided into sub layers, one of which is MAC (Medium Access Control) used to transmit signals owned by nodes connected to the network without any conflict. Zigbee is one of the standardized communication protocols on the MAC sub layer that are known to be reliable and low power. With zigbee, the researcher has the idea of ​​analyzing the power consumption level when this protocols are communicates. The communication system between the nodes was tested using xbee s-1 with arduino uno as microcontroller, and because xbee s-1 low power researchers gave solar cells as resources. Solar cells are used because they have self charging capabilities. System testing includes, changes in environmental conditions when nodes communicate. The last step in this research is to analyze the result data from the test to conclude the result of the research. The result of this research is zigbee communication using solar cell resources can be used in areas where the air temperature is stable and there are heat sources. The power of calor can provide arduino microcontroller power and xbee s-1 module to be used in communicating. Changes in working environment in the form of distance, delivery of packets, temperature, and time intervals applied by researchers can affect the level of power consumption. Researchers recommend environmental conditions that are used so that the system can be run optimally. The use of the zigbee protocol would be optimal if used at a distance of 60-70 m, data transmission by 60 - 80 bytes, temperatures at <30 and> 20 ° celcius, and time intervals 25-35 seconds.

Abstract

The method of conventional robotic arm motion is by forward kinematic, which moves by determining the time of deviation of each joint to reach a point. Unlike the forward kinematic, inverse kinematics move by determining the angle required to perform a motion. Forward kinematics is considered as method that utilizes trial and error, this method become less effective because it takes a long time. Meanwhile, inverse kinematic offers more practical solution with more complex computing calculations. With the development of microcontroller complexity on calculation inverse kinematic can be done more quickly by using parallel computing that can take advantage of all the existing cores on the microcontroller. openMP is a C ++ program directory that describes the use of application program interfaces to perform parallel computations in multiple memory environments. openMP becomes one of the programs that can be utilized to perform parallel computing. The result is, openMP able to divide the program so that the Squential program imposes its process on core 1 (30.74%). But in the parallel program the process load fairly even distributed, although it looks more burdensome to core 2 (30,7%) and 3 (20,38%). Accuracy calculation results from both methods are same, both have same nois and error that is equal to 0.4 cm from x axis, 1.5 cm from y axis and 1.06 cm from z axis. In addition, the error also occurs at the servo angle, where the average error in 1st servo is 1o, at the 2nd servo is 1.24o, and at the 3rd servo is 4.1o. When compared to speed, the parallel method performs all tasks faster than squential by 20 seconds (36.4% of the sequential time) for 4 servos and 10 seconds (22.2% of the squared time) for 3 servos.
