Initial Product.

Step 1:

Gather all materials , for making the sled base.

Step 2:

put all the materials together as shown in the picture.

Step 3:

Sled hitch!
• (1) 9 hole bar
• (1) 5 hole angle bar
• (2) 0.182" plastic spacers
• (2) 8-32 BHCS x 1/2
• (1) 8-32 BHCS x 1/4
• (3) Keps Nuts

Step 4:

Finishing The Sled!!!
• (2) 8-32 BHCS x 1/4
• (2) 2" (5.1 cm) Threaded Beams

Step 5:

We made our robot longer so that the robot could have more torque and we wanted to add a touch of our creativity.

Step 6:

Gear Ratio is 5 to 3 .
Why? Because we wanted our robot to go fast and for our robot not to lose as much torque so it can pull weight.
Input RPM: 105 RPM
Output RPM: 175 RPM
Input Torque:1.67 N•m
Output Torque:2.78 N•m

Step 7:

Wheel Diameter : 12.5 cm
Wheel radius: 6.25 cm
Circumference: 39.27

Step 8:

Vt= 114.5 cm/s
Va = 93.03 cm/s

Step 9:

We wanted to make our robot to pull the most weight in the shortest amount of time.
We changed our gear ratio from 1:1 to 3:5
We added bigger wheels for more torque.
Removed unnecessary weight from robot .
Added more weight up cront of robot to have more torque upfront.

Step 10:

Final Product:
added a 16 hole bar to keep the motors in place .

Step 11:
