  • First....What is torque?: Torque is a twisting force- (it doesn't do any 'work' itself- it is simple an application of energy). Work (or 'stuff') happens, when torque is applied and movement occurs.

    this shows that the robots will be better at pushing if that have alot of torque
  •  
    shows a great example of an inclined plane

  • This motor shaft will make 3 rotations, in the same time the output shaft makes 5 Gears used: 20 tooth on motor, 12 tooth on output Gear Ratio: 3:5 Power: 3/5x motor Speed: 5/3x motor (faster)
  • This motor shaft will make 1 rotations, in the same time the output shaft makes 3 Gears used: 24 tooth on motor, 8 tooth on output Gear Ratio: 1:3 Power: 1/3x motor Speed: 3x motor (faster)

    great ideas for gear ratios

    very helpful gear ratio chart
  •  
    the bottom two charts are good. It does make it go considerably faster
  •  
    It looks like a smart idea for designing the wheels maybe it would be possible to adjust it and make it stronger
  •  
    This is probably the best for speed and power(torque). The robot would be front wheel drive based on that if the nxt is on the back with the wheels the robot would flip or slide down due to the weight on the downhill side of the robot not the uphill side(assuming the track is at 22.5 degress

    I agree wit Josh this is what we need for the project
  •  
    this has some good ideas

      useful for different configurations, good to know
  •  
    This shows us the torque of the motor. Yes we have 9 volt batterys, the bottom of the page next to a picture are some gear ratios.
  •  
    it shows how we can adjust the gear ratios to give the robot more or less power while driving
