Stanford researchers at the Salisbury Lab have prototyped a wearable, articulated robotic device that can be attached to a person at the hip or other location to augment human task productivity. This mechanical "third arm" has many uses such as assisting abled users (e.g.
This compact, low-cost, high resolution angular position sensor is designed to improve the movement of rotary joints. The capacitive sensor, which includes two flat discs patterned with conductive material can be packaged in tight spaces.
