The biggest risk factor is the robot being unable to move or the platform not working by the end of this week. Some things that may contribute to this problem are if the custom IP block for the IMU does not end up being useful. As a contingency plan, we may send the IMU data from the Arduino through UART, which should make retrieving and using the IMU data easier. Another concern is the speed at which our linear actuators move. The fastest rate for change in angle will be when the robot is driving from a flat surface onto a ramped surface, so we plan to slow the robot down if the linear actuators are unable to adjust quickly enough. Before, our systems for the wheelbase and the platform were independent, but we think that we could have the two systems interact to solve this issue. Another risk is keeping the pistons still. To address this, we plan on wrapping the axis with yarn to keep it still. As a contiguency, we might hot glue the yarn for more security.
We made the changes to attach the electronics using velcro tape instead of screwing them onto the base. This was done to save time on reattaching/attaching the electronics on the board. The cost is $9.51.
There is a huge schedule change. We plan on getting the robot moving, the platform tilting, and the bot moving by the end of next week so that we can test and tweak the system. We expect to run into many issues, so we made this change.
