ROVER RUCKUS ROBOTS
As the direct result of our robot in 30 hours challenge, Overcharged and RevAmped proudly present to you: Curiosity! Building this right after kickoff, we designed our robot to resemble an actual rover, hence the name. We used relatively simple systems paired with Actobotics to make it easier to explain the design to you all through our five-part Ri30Hr update series (which you can check out here).
The concept of our design lies in the simple intake and dump design. In order to make an effective robot in a short amount of time, we designed a robot that could quickly grab minerals from the crater and deposit it from the respective side. To do this effectively, we used a 30:1 six wheel drive train, to climb the crater without slipping and maximize speed.
Our hanger is the most questioned part. It's similar to the Hot Wired latch on Res-Q. We have a servo that drives an axle which contains a spring. This distributes the hanging force on the robot to the spring instead of the servo itself. Pairing this with a strong motor like the NeveRest 60 made it extremely easy for us to hang.
RELIC RECOVERY ROBOTS
El Tigre is our second robot of this season. We noticed that the intake robots were extremely efficient in this game. We wanted to have a compromise: keep our innovative swerve drive while making room for the intake. The only way we could do this is by having an unorthodox intake system.
Most of these robots used compliant wheels, but we decided to take a different approach, using our tank treads to graph the glyphs. This was raised up using a ramp covered in Teflon and brought up to our flipper's claw, which gripped the glyphs prior to flipping them out for scoring. This was all topped off with a unique bottom scoring relic arm, which consistently scores a standing relic.
Our jewel arm had a trident shape bracing to guide the jewels away from the Cryptobox and to prevent it from reaching under the balancing stone. All of this when put together brought together an extremely compact and capable robot.
This was our initial approach to Relic Recovery. We chose to go for the claw design because it would be much more accurate for our Autonomous, especially with the Swerve Drive.
We used our improved version of Hot Wired's Swerve Drive that we call Swerve v2. It features NeveRest 20 Orbital Motors on the pod itself, which calls for an extremely compact pod. We had a dual motor lift to ensure both sides could lift our claw, which was powered by a four-bar linkage and two REV Servos. This provided us for a circular motion that would push aside other glyphs while gripping extremely accurately.
Since this robot was built during our League Meet staged, we had chosen not to focus on a Relic arm - rather, we focused on prototyping our new robot: El Tigre.
