Week 8

To design the sensor/potentiometer holder, I have discuss with my family relative to assist me in designing AutoCAD  2012 for sensor holder. All the dimensions were measured to make sure it is accurately measure the angle of ROM.
Using same material with mechanical, I decided to pick same thickness and material due to it's availability and sturdiness. These are pictures of sensor holder from AutoCAD software, showing the dimension, position and placement.

For motor driver, the L293D IC was tested to check the strength of motor torque to move the mechanical structure. But there are some minor problem, which is the prediction of current allowed in the motor driver when the DC motor on load. This prediction was based on L293D specification
