- Originally we planned to make a "finger" based climber but we realized that the "fingers" sometimes pushed the rope away instead of catching it. This made the climber require a longer amount of time to align.
- To circumvent this issue, we designed another prototype. This second model used velcro to catch a velcro rope. It is much smaller and easier to assemble, therefore taking up less space and time. Inspiration was derived from Ri3D 1.0
- We would also like to implement a "flip" mechanism which would transfer the climber from inside the hopper (most likely) to the outside of the robot, above the bumpers.
- Moving forward with velcro climber
- Decided on the use of 2x 775Pro Motors with a Dual Input 35:1 (5:1 and 7:1) Gearbox
- In progress: detection of top of rope, brake/lock to prevent descension
- Implementing sensors
- Considering the use of a wratchet and pawl lock (similar to 2016)
- Rope will be made of a tie down strap with velcro sewn on
- Will explore the possibilty of using a rope that does not touch the ground and one that does
- Controls: a need a joystick/toggle to ascend/descend, toggle to engage lock, servo/solenoid to relsease flip mechanism (toggle)
- Controls needed: input to initiate and maintain climber
- Auto flip out (needs to be actuated, not gravity propelled)
- Confirmed locking mechanism of a ratchet, pinned between two 1/4-20 bolts
- Updated CAD model
- Decided against the use of sensors
