A new idea is to have "tusks" that will swing out from the front of the robot and bracket the base of the tower, to align the robot properly. There will be stops to keep them at the right position once they swing out. They must be strong - this subteam needs to calculate the strength needed, for a 155 lb. robot moving at speed, so that the "tusks" don't break. | A new idea is to have "tusks" that will swing out from the front of the robot and bracket the base of the tower, to align the robot properly.

Drivetrain
Finalized frame rail dimensions. Need to make sure Inventor measurements match actual wheel & frame dimensions. Will bolt and weld corner brockets. Most motors are ready to mount. Encoders are mounted to the transmission.
Arm/Manipulator
Sprockets need a bit of work to get chain to fit properly. Parts for both arms are in, except pins for telescoping arm, which will be in Tuesday. May need to get tube materials (appropriate sizes) - check with Harris. Must make sure to take all precautions to keep chain on sprocket(s).
Minibot/Deployer
A new idea is to have "tusks" that will swing out from the front of the robot and bracket the base of the tower, to align the robot properly. There will be stops to keep them at the right position once they swing out. They must be strong - this subteam needs to calculate the strength needed, for a 155 lb. robot moving at speed, so that the "tusks" don't break.
Once robot's aligned, minibot (mounted on drawer slides) will slide out to pole, driven by a motor and timing belts (or surgical tubing, gas shock, etc.). A "V" notch will guide the minibot into position on the pole. Minibot may be held in place by a vertical peg in the drawer, then will lift itself straight up off the peg. Need to know the "envelope" within the robot that the minibot & drawer & slides will fit inside.
Minibot: two angled stock drive wheels, and one back wheel (which will be made of polycarbonate). A tray on the back wheel side will hold the battery. There may also be a "common form factor" 12x12 box that would allow us to loan the minibot to another team. Need to figure out an "off" switch once the minibot triggers the tower.
Electrical Main
Met with Programming to discuss what kinds of controls are needed. New signal light concept: PVC wrapped with LED in various colors (blue/white/red/green). New electrical layout with drop-pan design in drivetrain. There's a full sensors list on the wiki now (coordinated with Programming).
Electrical Controls
.
Programming
Need to determine positions of sensors and communicate to Electrical and Mechanical.
