This was a test using dual 1/2" rollers wrapped with duct tape. During the test, the rollers separated slightly after coming in contact with the ball once hitting the 3" limit(simulates a spring loaded roller system). Original video unavailable.
Read postReview the PDF linked below for calculations for the lifting arm. If the PTO is driven on the low gear side (14 to 64), then an additional reduction of approximately 8:1 will be required to drive the arm. This is easily achievable in two stages. If the PTO is…
Read postDuring the previous two days, we attempted to design and prototype different roller orientations with minimal success. Before we were able to record a video of the horizontal roller setup, we determined that the setup held the ball well(going forward). While…
Read postToday we began to manufacture the robot frame. Currently the CNC is turning them out after a laborious 3 passes in order to bore all the holes. Hopefully we will have them done and ready to ship out by tomorrow afternoon. We also furthered our progress on the…
Read postMANUFACTURING Today, construction on the tensioner cams was completed. PROTOTYPING Today we did extensive prototyping with vacuums. We continued to work with the two-stage impeller assembly hooked up to 2 fisher price motors. The impellers are currently…
Read postWe dropped off the wheels, bearing housings, and gearbox spacers at the anodize shop today. Hopefully we should see them back in a few days.
Read postDESIGN Today, the design team worked to finalize the drivetrain. The baseplate will be sent out to be cut by Mike D at NASA Kennedy's waterjet shop first thing tomorrow morning. MANUFACTURING The CNC was running all day to cut all of the drivetrain tensioner…
Read postToday, Team 254 finished CNCing the wheel hubs for each team and cut the stock needed for the cams. In the meantime, the CAD team continued tweaking the baseplate design and other groups continued working on prototype methods of handling the soccer balls. One…
Read postAfter almost 18 hours of machining the last two days we completed the first operation on all 70 wheels. We began the second operation and now have 20 completed wheels. The rest should be completed in ~3.5 hours tomorrow. We also began making wheel and gearbox…
