Mechanical Problems
- The left-side possessor bottom roller actuator failed (again). This caused a failure to possess on several occassions before the problem was identified and repaired before match 23. Photographs show that the bottom roller deployed slowly during the practice match (causing a delayed autonomous kick). Deployment at the start of DEWBOT's first three qualifying matches was on-time.
- Pivot transfer axles and wheel axle collars need to be checked after every match.
- During the final 30s of the practice match, the drive-train ceased operating properly. Wheels were stuck in an "X" configuration. We could not move. The problem was attributed to a bad battery (#7), which waas retired from competition service and is now a pit battery only.
- On several occassions, photographs caught the pivots in unnatural positions (position which the software should not drive them to).
- In playoff match 1, all povots started rotating uncontrollably at the start of the competition and did not stop doing so until the match end. Ben offered the following hypothesis: After the robots were placed on the field and turned on, we were told to turn off robots for award ceremonies. Following the ceremony, the robots were turned on and conpetition immediately started. Ben believes that the controller did not have sufficient time to go through its startup sequence during the abbreviated start.
- We became stuck in the goal during playoff match 2. Could not escape. May be due to new rear treads (bicycle treads) having lower friction coefficient.
