Final Project

1
Final Project

• Maura Curran and Emily Delisle

2
Project Ideas

• A robot that will type its name.
• Too complicated- too many keys in different
  places
• A robot that will type a math problem
• Subtraction is easiest
• stays in the same line and there is less chance
  of hitting keys in another row

3
What worked - and didnt

• Two arms each with two fingers moving in opposite
  directions
• didnt work - in order to make the fingers go
  in different directions, they had to be attached
  in a way that gave them no power
• One arm with one finger to hit each key while
  the robot moves back and forth
• this worked but still had some problems

4
Problems

• Giving the finger enough power to hit the key
• solution - add weight to the robot - coins and
  rocks
• The robot was too heavy to move
• solution - give it more power, and remove some of
  the weight

Our robot after the extra weight was added. (Her
name is Zoe.)
5
More Problems

• The finger stayed on the key too long, creating
  strings of numbers
• solution - use a small axle for the finger so it
  makes a full rotation, tapping the key as it
  swings

Us - before we ran into all these problems
6
Even More Problems

• The robots movements were inconsistent. It hit
  different keys each time we ran the same program.
• Solution
• changing the pulleys into gears
• changing from a rack and pinion to wheels

Zoe with added gears, but still using a rack and
pinion.

Victory at Last!!!

• Zoe was able to move smoothly in a straight line,
  and hit keys more consistently
• She was able to type 7-70 except when she
  was being taped

Zoe, finally working!!
