We brainstormed ideas for the sleds based on what we have used in previous seasons and what we have seen other teams use. | ||

pros: [ | ||
- *Stability:* Triangular sleds may offer increased stability due to their three-point contact | ||
- *Optimization:* Due to the triangular shape, it is easy to cut and change | ||
- *Airtime:* When they contact the middle barrier, the triangle becomes tangent to the middle bar, guaranteeing airtime | ||
], | ||
cons: [ | ||
- *Safety:* The shape has sharp edges that are prone to poking something | ||

pros: [ | ||
- *Friction:* Depending on the design, a circular shape might reduce friction as the sled moves, contributing to smoother and more efficient sliding | ||

cons: [ | ||
- *Optimization:* Due to the circular shape, the shape for these sleds need to be cut extra precise | ||
- *Steepness Limitations:* This type of sleds cannot be steep at all | ||

image-width: 50%, | ||
pros: [ | ||
- *Strength:* The materials are made out of gussets and not lexan, making them much stronger | ||
- *Durability:* Gussets can contribute to improved durability by reinforcing key stress points on the sled, reducing the risk of damage or failure during use | ||
], | ||
cons: [ | ||
- *Stiffness:* Although they are strong, they cannot bend and are stiff when contacting the middle barrier | ||

notes: [ | ||

The quickest way to get from one side of the field to the other is by crossing over the middle barrier. We will need some type of sleds on our robot in order to achieve that goal. | ||
|
||
Sleds work best on low-friction surfaces or structures that allow a robot to slide or move smoothly across. Specifically for this challenge, the sleds need to help the robot glide over the middle barrier. | ||

After brainstorming ideas for the sleds, we created a decision matrix with the following criteria: | ||
|
||
#nb_matrix_criteria[ | ||
- Durability - How long the sleds can be used before they need to be replaced | ||
- Impact Resistance - How resistant the sleds are to single impacts | ||
- Maneuverability - How maneuverable the drivetrain is with the sleds | ||
- Flexibility - How versatile the sleds are for moving across different game objects | ||
- Weight - How little the sleds weigh | ||

criteria: ( | ||
("Durability", 5), | ||
("Impact Resistance", 5), | ||
("Maneuverability", 3), | ||
("Flexibility", 3), | ||
("Weight", 1), | ||
), | ||
choices: ( | ||
("Triangle Sleds", 2, 4, 4, 4, 4), | ||
("Circular Sleds", 2, 3, 3, 4, 4), | ||
("Gusset Sleds", 4, 3, 2, 1, 3), | ||

#nb_admonition(type: "select", title: "Final Selection")[ | ||
The triangle sleds exhibit strong performance in most of our criteria, with the only weakness being its durability. | ||
