The robot assists a person who has lost the use of one leg through paralysis due, for instance, to a stroke or polio. The robot is attached to the leg to help the user walk more securely and naturally.
The Walk Assist Robot is attached to one leg to support rehabilitation for function recovery. After rehabilitation, the robot helps with typical activities in daily life such as walking on level ground, climbing and descending stairs, sitting down and getting up from a chair, climbing hills and descending slopes, using a toilet, using a wheelchair, getting in and out of a car's passenger or back seats. With the support from the robot, a user can become more independent for a full and active life.
Intelligent Multi-Sensor Control (harmonious control)
A position sensor on the thigh and a pressure sensor on the sole of the foot detect the user's thigh position and the weight put on the foot. Based on the user's stride and stride, an actuator at the knee regulates action to achieve the best walking assistance.
By calculating walking speed, the user is able to walk naturally and with confidence at a preferred pace.
Timing Lock Mechanism
A special link mechanism at the knee joint ensures a secure lock (without the knee bending) when the leg swings and plants the weight-bearing foot on the ground, so that the user can walk with confidence.
Lightweight Materials
Ways to lessen the burden on the user through weight reduction such as using CFRP as the material for the body were devised.
Using original architecture and algorithms, TOYOTA seeks to develop a commercially viable Walk Assist Robot that supports freer, more secure and independent mobility in daily life.
