KURSI RODA ELEKTRIK DENGAN DUA MODE: KONTROLER JOYSTICK DENGAN INDIKATOR SAFETY
Abstract
Movement aids for persons with motor systems especially in foot defects are very important because people with disabilities also want to move freely to a place without burdening their family or friends. Therefore, this electric wheelchair research was made with the aim of facilitating the movement of people with disabilities to move towards a place or do something. The design of an electric wheelchair to help move with a joystick control is connected with the Arduino Minimum System. If the joystick lever is directed forward, back, left, and right, the joystick command will be processed by the Arduino Minimum System, thus providing voltage to the motor driver and the electric wheelchair can move forward, backward, turn left, and turn right. The use of ultrasound is the safety distance between the wheelchair and the object behind it, safety distance is used 1 meter. The results of testing the joystick command which is done 25 times get 88% forward accuracy, back 100%, turn left 100%, and turn right 100%. The test results for the average speed of an electric wheelchair with a patient weight of 50kg-60kg are 2.3 Km / hour. The automatic braking test results is 100%. The test results of battery capacity during using the electric wheelchair were obtained for 4 hours with a patient weight of 55kg and testing the terrain of a wheelchair capable of climbing terrain with an angle of 6̊ high 6 cm and 56 cm long and unable to climb more than that.
