DIMENSIONAL SYNTHESIS OF PLANAR SIX-BAR LINKAGES BY MECHANICALLY CONSTRAIN A PRR SERIAL CHAIN

ABSTRACT In this paper, we consider the problem of designing planar six-bar linkages which can be driven by prismatic joints at its base. We explore various ways on how two RR chains can be used to constraint a PRR planar serial chain such that the system yields one-degree of freedom yet passes through a set of five specified task positions. We formulate and solve the design equations as well as analyze the resulting planar six-bar linkage. We demonstrate the synthesis process with the design of the seat of a wheelchair such that it is able to transform itself to be used as a rehabilitation guide during rehabilitation

Run Chicken Run: Physical metaphor augmented wearable movement-based interaction

ABSTRACT This paper presents our prototype Run Chicken Run which is a game platform where user can interact with a hacked electric toy "E-chicken" through physically metaphorical movement. By wearing input devices on elbows and then flapping arms, user can control the pace of movement of the E-chicken. In this way, the user interacts physically with the toy and socially with other players as well. To enable this, the game platform employs low-cost, readily available sensors, wireless modules, and microcontrollers
