1. Bumper Concepts

2. Overview Bumpers are an import feature as a backup system to proximity sensors. Bumpers are an import feature as a backup system to proximity sensors. It ensures building and equipment protection. It ensures building and equipment protection.

3. Needs Addressed  SAFETY (1)  Cost (5)  Easy to manufacture (11)  Robust (6)  Wow Factor (3), (8)

4. Issues  Must be designed to provide safety to the robot it’s self as well as its surrounding environment.  Should be removable to maintain a modular robot.  Should not reduce accessibility of components.

5. CONCEPTS  360-Degree Wrapping A bumper would have 360- degree coverage around the robot ie. (bumper car)A bumper would have 360- degree coverage around the robot ie. (bumper car)  Stoppers Specifically localized shock- absorbing material.Specifically localized shock- absorbing material.  None RP100 will have no bumper.RP100 will have no bumper.

6. Preliminary Analysis  360-Degree Wrapping ProsPros  Complete coverage  Inexpensive  Easy to attach ConsCons  Comprimises accessibility CostCost  4.25x.5”: $8.22/2’  Stoppers ProsPros  Easy to replace  Minimal space required Cons  Low WOW factor  Partial protection CostCost  ½” circular stopper: $11.91/pk of 64  None ProsPros  Very Inexpensive  Will allow time to develop non- backup sys. ConsCons  No protection CostCost  N/A

7. Final Concept None / 360-Degree After the filtering of our concepts through the concept selection scoring process we have concluded that no bumper would be the first choice. However it is believed that the 360-degree bumper should be developed for safety reasons.
