Justin and Chris’s Space Drill

For our project, we decided to create a handheld device that can screw/unscrew a nut and transfer it from one bolt to another. The main idea behind our project was to use motors and tires so that the spinning wheel with the grip of the rubber could screw/unscrew the nut. At first, we started off with two motors but it turned out that it made our device heavier and it was unnecessary so we modified our device to adapt to one motor.

 

Also, we added a claw on the opposite sides of the motors to transfer the nut after unscrewing it. At the tips of the claw we attached small rubber pieces from our Lego set to ease the task of gripping onto the metal nut. We found that this complicated the overall objective, especially when wearing a space glove and only using one hand. Therefore, we discovered a better alternative, a magnetic pen. We attached a magnetic pen in the spot where our second motor was originally placed. This magnetic pen makes it easier to twist off the nut and transfer it over in the correct placement to start screwing the bolt in.

 

Finally, our motor is programmed to respond to a touch sensor on the bottom of our brick. By holding down the button, the tires spins in one direction. When the button is released, the motor is programmed to spin in opposite direction the next time the sensor is pressed.


Overall, our original power tool has been significantly modified in order to create the most convenient and effective space tool.
