During the second and third weeks of the Easter break (13th to 22nd April), the team rebuilt the entire robot with new parts. (Before to the left and after photos are below).
The laser cut MDF which provides the different levels was painted off-white.
The MDF parts that make up the claw were remade in white, opal acrylic; this reduced the friction on the guide rails.
The lintel mechanism was remade in laser cut white acrylic for strength and accuracy.
The PTFE casters were redesigned to be more adjustable; so as they ware down they can be moved, allowing the back of the robot to maintain the same height.
Poor quality micro switches were replaced with industrial standard switches.
The tapered shape at the front is widened allowing more room for error when collecting column elements.
Last but not least, the guide rails, track and vertical encoder was extended. This now gives the claw a 50mm higher lift. The team plan to use this to place 2 extra column elements on top of their original tower. This will raise the total points per match from 29 to 42.
Last few jobs are
- The pull cord
- Obstacle avoidance
- 90 second shut down timer
- Fine tuning all programs
