Motor selection: Our motor needs to generate 9Nm of torque and needs to be inexpensive to purchase.  Exceed 36V motors are available but those motors are over our budget so it is not reliable. Other types DC motors, such as brushless and stepper motor, require microcontroller to run them under control.

Changing in direction of motor can be controlled by H­Bridge system. this H­Bridge system has wide range of voltage input and if we have a range of required power, our EE team can make one for our motor.  This H­bridge requires: 

­ 4 of transistors( for control electical signals) ­ 4 of resistors ( regulate the current flows)  ­ 4 of diode( for control direction) ­ 2 switches( for control voltage flow).
