Abstract

      The lifestyle of the elderly or patients with leg muscles weakness must use a wheelchair to transporting between the bed and toilet. Found problem was the transition between a wheelchair and bed or flush toilet, the elderly or patients must stand up and rotate the body to sit on a bed or flush toilet, and vice versa, they may be able to fall, resulting in other disadvantages followed. The purpose of this research was intended to design and construction of a movement support device for transporting the elderly or patients with leg muscles weakness between a wheelchair, bed, and toilet for home use. The device can be transporting the elderly or patients with leg muscles weakness between a wheelchair, bed, and toilet, without standing up and rotate the body to sit on a bed, wheelchair or flush toilet which was the prevention of falls. This device composed of electronic systems and mechanics part. The electronics system was used to control the operation of a device. It consists of a microcontroller, h-bridge drivers, alarm with buzzer, limit switch, lithium-ion battery with charger and C language program. The mechanics part was designed and constructed by using the steel, DC motor with gearbox, electric linear actuator, two polyurethane wheels and two rubber wheels. The results of transporting up and down of seat base, the current, power, time and energy used in the electric linear actuator, will increase according to the load (10 kg - 100 kg), while electric linear actuator has to transport up or down. But the average speed reduced due to the electric linear actuator has increase weight, resulting in the time of transportation of the seat base of the device increase. The results of transporting forward of the device with two-speed levels, the current, power, time and energy will increase according to the load while the device has to transport forward with high speed and low speed. The average speeds were reduced due to the device has increase weights. On the other hand, resulting in the time of transportation increases. And the result of the sound level while the device was transporting forward and backward, it has sound to 55.3 dB which was in the standard (not more than 60 dB). Also, the device had weighed 15.3 kilograms.
