Our most significant risk is generating enough torque to lift the stand. We are currently managing this risk by purchasing a new motor that has almost 7 times the amount of torque than the one we have now. Furthermore, we have developed some ways of lightening the top of the stand. If this does not work, we will buy a motor with higher torque by the end of next week. We can also start the stand at a higher position that the motor is able to lift.
We did not make any significant changes to the design of the system other than purchasing a new motor. We also decided to include a shelf to hold the linear actuators, although this change will not incur major costs or threaten our existing schedule. This was necessary so that the laptop will start at a lower angle.
