STWW Project - Sharioto

Sharioto

Our wheelchair Sharioto is equipped with different types of distance sensors (ultrasonic sensors, infrared sensors based on triangulation and a ‘Lidar’ infrared scanner) and with a gyroscope for heading correction. A laptop processes the sensor information and deals with the intelligent control of the wheelchair: joystick signals are read from the wheelchair CAN-bus by means of a DX-key (a hardware interface to the original DX-CANbus system on the wheelchair). These signals are modified by the algorithms on the laptop, and the modified signals are sent back to the wheelchair motors. To make the wheelchair comfortable for our test persons, we equipped it with a head support and an adaptable sitting module.
