15. Design of the Prototype Bionic arm The mathematical
modelling and the range of joint variables are used to design a
prototype arm model. A solid model is rendered from the Creo
Parametric developed by PTC. A control mechanism is developed using
a microcontroller circuit. A light weight, prototype physical arm
model is made to test the control mechanism. Potentiometers are
used as sensors (input). The servo motors are used to move the
joints of the arm(output).
