Resurrection & Revival
The robots for our 9th season competing in the FIRST Robotics Competition are named Resurrection & Revival. With Resurrection, we go to the South Florida Regional in West Palm beach. Resurrection performed fantastically. We were so consistent with getting the cargo bonus for delivering 20 or more cargo into the lower hub. We got rank 1 out of the 33 teams and won the regional which got us qualified for the FIRST Championship 2022. If that wasn't enough we also received the Engineering Inspiration Award. After South Florida, we compete with Resurrection in the Orlando Regional. We some modifications we were able to make our robot also consistent with getting the cargo bonus, but then by scoring in the high hub. In Orlando, we experienced a lot more defense and therefore we had to work harder for our scores. But we were still able to get rank 3 out of the 56 teams. We got into the semi-finals but were after 3 exciting matches eliminated. We received the Excellence in Engineering Award. Team Rembrandts exist now for 10 years, we wouldn't exist if it weren't for Ron Visser and all his hard work for our team and the FIRST community in the Netherlands. Therefore we were so excited that with all his dedication and hard work Ron Visser received the Woodie Flowers Finalist Award at the Orlando Regional.
Even at the FIRST Championship in Houston, we kept on breaking new records. In between the regionals and the FIRST Championship, we made some modifications, which helped us get at rank 10 out of the 76 teams in the Roebling division. The highest-ranking ever got at a FIRST Championship. Unfortunately, we got illuminated in the quarter-finals, but we were honored to receive the Excellence in Engineering Award in the Roebling division.
- Determine game tasks, such as taxing in auto and scoring lower hub.
- Determine the robot skills required to perform the skills. (Both required skills and beneficial skills.)
- Analyze data from previous games to determine the number of points needed to get the desired result.
- Analyze the number of cycles needed to reach the number of points.
- Combine the information to form a list of required robot skills for winning a regional according to historical data.
- Determine the strategy.

TELE-OP CYCLE TIMES
- It is expected that cargo will bounce most often to the orange areas.
- It is expected that cargo will bounce less often to the yellow areas
PLUG & PLAY
THE UNIT DESIGN PHILOSOPHY HELPS TO
- Iterate fast on multiple ideas/concepts and upgrade the robot throughout a competition season.
- Make as effective use of our “Robot-Play/Test-Time”.
- Be able to iterate our robot without being hindered by international travel and logistics.
- Easily assemble and disassemble the robot multiple times.
GOALS OF THE UNIT DESIGN
- Design physical stand-alone units which can run stand-alone.
- Units are testable without robot environment.
- Enable off-line development and test of upgrades.
- Enable parallel integration, thus short integration time.
WEIGTH & DIMENSION
Dimension l+w+d = max 1520mm
Max weight = 23kg / 50.70lbs
PCH OR PDH
Each solenoid is routed to the PCM in the robot
core. Other 5V-12V below 2A are routed to
the PDH in the robot core
Through the drivetrain, there is a CAN BUS
wired with PCB hubs near the subsystems for
their CAN connections (Sensor/Motor/
Controller) first CAN component routed to
can master in Robot Core (Can ID-X00) units.
The needed amount of storage tubing is
supplied from the robot core depending on
- Subsystems are mechanically and electrically connected together.
- Easy to work in parallel testing in the system while repairing another subsystem.
- Combining subsystems lead to a more complex design which might be ineffective.
THE TIME YOU SPEND ON BOTH SUBSYSTEM A AND SUBSYSTEM B, REDUCES THE TIME YOU CAN
SPEND ON OPTIMIZING A SUBSYSTEM
|Prototype all the concepts you come up with||Optimize a system you know that works|
|Use machine-shopped wood||Use laser-cut wood to test several configurations|
|Prototype all systems separately||Have a standard drivetrain to test prototypes on|
|Connect motors directly to the battery||Have a controls board including Rio, PDH, etc.|

This year Team Rembrandts is once again a member of the open alliance, an alliance of teams that are sharing their plans, findings, and progress throughout the entire build season.
The vision of these teams is not to keep everything a secret, but to inspire others with the
information is given and gives them an opportunity to bring out the best of themselves.
Our build thread is open on chief Delphi for everyone and questions asked are answered to help each other in the best way possible.
