The head must traverse its maximum vertical travel in 20 see or less and stop within 0.5 in of a desired location. Limit switches must automatically shut off the motor at each end of the head's vertical travel. Design a device to transfer a 100-kg paraplegic patient safely from bed to wheelchair and vice versa. The patient has good upper body strength but no control of th lower extremities. Your design should be operable by the patient with minimal assistance.
Safety is of aramount concern.
Design an indoor bicycle exerciser similar in concept to the wheelchair exerciser shown. The concept is to provide twin rollers to support the rear wheel and a single roller for the front wheel. Design all parts with suitable geometries and materials for infinite life. Telescopic robotic hand for Laparoscopic Surgery Laparoscopic surgery is performed through small holes with video cameras for observation and long surgical instruments. A telscopic hand is needed so that the surgeon will operate his fingers and their motion will be duplicated inside the body by the arm.
