Robotic drivers are used in vehicle performance tests such as fuel consumption. The test vehicle is driven on the dynamometer for driving test cycles with defined time and speed. To compare fuel consumption of various vehicles appropriately, better control performance is necessary to maintain the target vehicle speed. However, it is difficult to realize better control performance because a vehicle...
Vehicle performance tests are conducted to evaluate factors of vehicle performance such as fuel consumption and durability. Robotic drivers are often used in these tests to ensure that performance evaluate is reproducible, and various types of vehicles have been tested. Manual transmission (MT) vehicles are widely used and represent about 50% of vehicles in the world. When the driver selects the gear...
We previously proposed a motion support robot and conducted experiments in which a C5-level cervical cord injury patient used the system. This paper proposes to offer motion support to a C4-level spinal cord injury patient who suffers from paralysis of the limbs. Electromyogram (EMG) signals are used to determine the user's intentions. The proposed motion assist robot can then support flexion and...
Cervical Cord Injury(CCI) causes a form of upper limb dysfunction. In an individual with C5-level CCI, which is the most frequent of all eight types of CCI, force can be applied in the direction of flexion by the biceps brachii, while extension force cannot be applied by the triceps brachii. Without the ability of the triceps brachii to exert this force, individuals with a C5-level CCI cannot propel...
Thousands of individuals of all ages are living with a spinal cord injury as a consequence of a traffic, or sports accident or other calamity, and many of these individuals incurred a C5-level spinal cord injury, with a loss of the ability to use their legs and exert extension force from the elbow joints. Many of the motions that are necessary in daily life are difficult or impossible to perform with...
In this paper, we propose a robotic system for assisting patients who have upper limb dysfunction in performing reaching movements through flexion. Since upper limb motion is more strongly needed than lower limb mobility for near work, a patient's level of recovery of upper limb function influences daily life. Recently, with the widespread application of robotic technology in rehabilitation medicine,...
Cervical Cord Injury (CCI) is a dysfunction of the upper limb. In an individual with C5-level CCI, which is the most frequent of all eight levels, force can be applied in the direction of flexion by the biceps brachii, but extension force cannot be applied because of the triceps brachii paralysis. Persons with C5-level CCI therefore cannot operate a wheelchair up an incline and over carpet. In this...
For finish processing of limited-production diversified products of complex shapes, the use of a bilaterally controlled robot is in some sense inevitable. However, a bilateral control system is very difficult to operate because a worker must be in constant contact with the slave tool. So, in this paper, we propose a method to show the shape of the workpiece from the estimated curvatures of its parts...
