The issue of global warming is very strong in the force in the procession, the damage caused by global warming is very influential in the survival of living beings. The methods performed in this study are experimental methods. The experiments performed were to make a design and to become a unity so that it formed a tool of electric bicycle transportation that can be used well. This thesis author devise and assemble electric bicycle using DC electric motor 24 Volt 250 Watt and 3000 rpm. The power system used is 24 Volt 12 Ampere battery. From the results of the test and analysis of data that has been taken on the electric bicycle obtained data of the average speed obtained by the electric bike with a load of 78 = 4.94 m/s, load 83 = 4.59 m/s, load 88 = 4.25 m/s, power output to drive electric bicycle with load 78 = 266.679 Watt, load 83 = 263.810 Watt, load 88 = 258.984 Watt. Isu pemanasan global sangat kuat di gencar disuarakan, kerusakan yang disebabkan pemanasan global sangat berpengaruh pada kelangsungan hidup makluk hidup. Metode yang dilakukan dalam penelitian ini adalah metode eksperimen. Eksperimen yang dilakukan adalah membuat sebuah rancangan dan merakitnya menjadi suatu kesatuan sehingga terbentuk sebuah alat transportasi sepeda listrikyang dapat digunakan dengan baik. Skripsi ini penulis merancang dan merakit sepeda listrik dengan menggunakan motor listrik DC 24 Volt 250 Watt dan 3000 rpm. Sistem daya yang digunakan adalah baterai 24 Volt 12 Ampere. Dari hasil pengujian dan analisis data yang telah diambil pada sepeda listrik didapatkan data berupa kecepatan rata-rata yang didapatkan sepeda listrik dengan beban 78 = 4,94 m/s, beban 83 = 4,59 m/s, beban 88 = 4,25 m/s, daya output untuk menggerakkan sepeda listrik  dengan beban 78 = 266,679 Watt, beban 83 = 263,810 Watt, beban 88 = 258,984 Watt.

This article illustrates a technique for tracking longitudinal wheel slips in real time using an embedded microcontroller to map current consumption against real-time current consumed by the engine. This system can be used and operated separately of each other on more than one wheel. To detect wheel slippage, a predefined slip curve mapped to a specific DC electric motor is mapped against the current consumed by the same operational motors. This paper also recommends a convenient control algorithm to calculate its slippage of the wheel in real time. This approach is implemented using distinct load and terrain on a planetary exploration robot.

This paper represents the performance of placement control of step motor (Brushless DC electric motor) using LabVIEW. Step motors are Applicable in many industries and factories where accurate control of motor position is necessary. In this work, half step and full step manner of step motor control is implemented. The experiment outcome show that half step manner makes an angle of 0.6 degree per step (300 steps), considering full step makes 1.2 degree per step (150 steps). With LabVIEW the arrangement has friendly communication, better control result and uncomplicated control in both ways.

A human-robot coexisting system requires the essential function such as safety and flexibility which are not common in general industrial robots. To build up such a robot system, an inherently flexible actuator must be effectively used rather than a conventional rigid actuator. A pneumatic actuator seems just available as such a human friendly actuator. In this paper, a property of the flexibility of pneumatic actuator is analyzed compared with a DC electric motor. Also the application of a pneumatic rubber artificial muscle actuator to a rehabilitation robot is discussed. The results show that a pneumatic actuator can well work as one of human friendly actuators with cooperation of a proper control strategy.

To make it easier for farmers in terms of maintenance and transportation of community-owned coconut and palm oil crops, the team tried to make a design for testing the thrust of a 250 Watt DC motor powered by solar heat for boat propulsion, by testing the boat propeller with variations in the diameter of the propeller 17.5 mm, 15 mm, 15.5 mm, 14.8 mm, and 14.5 mm, as well as testing with variations in driving rotation and variations in driving rotation with the number of gear teeth 11, 16, 20, and 22. From the calculation of the torque obtained is 1,090 Nmm so that the diameter is obtained propeller is 5 mm. Thrust force test results obtained vary depending on the diameter and variations of the rotation of the propeller drive so that an adequate diameter is obtained by using a diameter of 14.8 mm with a current of 9.2 A with a thrust of 7.5 kgf. Meanwhile, for an adequate variety of the driving speed, the number of teeth is 20 and the thrust is 7.5 kgf and the current is 10. This value meets the requirements because the current strength does not exceed 10 A. From the test results, it can be concluded that the design and analysis are very fulfilling needs.
