Raiderbot X, 26 Days to Robot Ship
This is an email I sent to the Raiderbot mailing list. I think it sums up everything that is going on.
The bad news:
We are still a week behind largely due to delayed shipping of supplies and bad planning on my part. We have no driving robot, nor do we have a fully functional arm. If we add up all the hours, we have little over 60 hours (2.5 days) of work time left in the season. Also significant is the fact that too few people have been showing up.
The good news:
We have the aluminum tubing required for the chassis and have enough already cut for one chassis, ready to be welded using the jig constructed last week. HyTek has donated more plastic to us than we’ll ever need this year. We received the materials for the arm today and should be ready to start building tomorrow.
The roller claw beta prototype (demonstrated last week) looks very promising. Great job to everyone who helped design and fabricate it!
We have located a machine shop (Viper) that has the capabilities and is willing to manufacture our swerve modules (for the drive base). Spencer Hedrick is currently waiting to hear back from them regarding the cost and time of fabrication. We will know by Friday what the decision is. If the price is affordable, we hope to have the modules (and one robot) finished by the end of next week.
The scary stuff:
We need our first robot finished by the end of next week and our second robot by Wednesday of the following week. Please realize that although next week is only Week 4, it is already Week 4. It was our original plan to have the swerve modules finished first, but because the machine shops will not finish fabricating the swerve modules by the end of next week, we need to have everything else finished and nearly perfected by that time. This includes the:
- Roller claw,
- Four-bar linkage lifting mechanism (with milled aluminum tower),
- Electronics board, and
- The attachment of every necessary motor, sprocket, wire, belt, chain, pneumatic, and pulley we need on each of the two robots.
If all 46 members of our team meet and work consistently, this is entirely possible to accomplish in less than a week. At the current rate of attendance, however, this will not happen. Please also consider the fact that I haven’t even begun to describe what we need to do regarding the business plan, T-shirt design, battery cart, robot cart, scouting, pit build, pit panels design, minibot design, etc. There are too many jobs and too few people who come to meetings!
I am fairly happy about the attendance of the longer (Monday/Friday/Saturday) meetings; we got a lot done last weekend. However, attendance of the shorter meetings has been disappointing at best and unproductive at worst. Because we end two hours earlier, we need more people and dedication to maximize the use of our time in the shop.
It is our (me and Lipi) job as program managers to keep track of what resources we have to work with and keep the team on track for a successful season. Here, a “successful season” means we have completed the following (among other things) by Monday, 2/21, which is 26 days away:
- 2 Robots
- 2 Minibots
- New website
- Battery cart
- Robot cart
We hope we are doing a decent job, but in being effective leaders, we depend on each of you. Regardless of your individual jobs, regardless of how small it is, regardless of how much it may or may not seem related to robots at all, everything you put into the team brings us closer to success.
We would like to go to every meeting knowing everyone will be there, but this has not been happening. We completely understand if you have other commitments (we do, too), but please let us know (by email, word of mouth, phone call) if you will not be there—then at least we can plan things accordingly so we aren’t caught short at the end.
Currently, the programming subteam is the only subteam that is (far) ahead of schedule. (Mechies, are you seriously going to let the proggies outdo you?) Congratulations. :)
Again, the roller claw is looking great. Please be there tomorrow to help finish building the arm and test it on the kitbot.
