FLL Into Orbit 338 Points - Team 20540 Orbiters

Team 20540 Orbiters accomplished 14 missions, earning 338 (max 342) points during a 2:22 dry run. This is the 7th version of DreamChaser. The main idea of the robot is to benefit on 2 different approaches: bumble bee and combined harvester. The bumble bee approach is to let the robot go around the mission models and accomplish different missions like what launch 3 here in the video did. However, the drawback of bumble bee approach is that it is time consuming to navigate the robot around and align to desired positions without errors. The combined harvester approach is to let the robot go a simple straight line and use attachment to finish all the jobs around. Launch 1 and 2 in this video represent the combined harvester approach. It saves a lot of time. And, the robot is very reliable. The drawback is sometime it is not possible to go a simple route and let attachment do all the jobs. There is some obvious drawbacks of the DreamChaser 7. 1) The attachment at the front is really heavy. We added 2 counter weights at back to balance it. 2) The robot itself is kind of big, making it really hard to navigate around. 3) The attachment is at front rather around robot. Making it hard to organize all operation parts without interfering each other. Also, it takes more time to switch attachments with current design. 4) There are too many external gears on the robot base. These should be on the attachment. 5) One more thing, the wheels we are using are 62.4mm x 20mm. They wobble a lot. 6) Our programming really sucks since we only put 10% of the effort on programming and 90% of the effort on building the robot. Anyway, just to share our robot adding more fun to the FLL community. #firstinspires #OMGRobots #STEMsquad
