Home Base Feet
2005-06-08
Enlarge diameter and height of the four elastomeric feet at screws to
increase traction on smooth floors. Home Base does not slide when
robot docking.
Wheel Hole
2005-06-23 Close axle hole to reduce migration of dust under wheel cover.
Caster Material
2005-06-24
Change front caster material from Acetal to Nylon 801 (also black).
This material is more abrasion resistant and withstands life tests.
Long term fix is to design a swivel caster (in progress).
Motor Power
Wire
2005-07-27
Main brush motor revolves in mounting brackets and this causes
fatigue on the power wire. More flexible wire chosen.
ESD protection
2005-08-05
ESD entering the robot via the charging port may damage these
FETS and cause the robot lose the ability to control the charging of
its’ battery. Protective components added to board.
Wire Bail
2005-08-19
We have seen a few cases of abraded wires. To avoid wires
dragging on floor, wire profile is reduced so it does not protrude.
Software 1707
2005-08-23
1.
Solve circle dance (dirty wheel encoders) with open loop mode.
When in this mode may arc and have a different velocity.
2.
Recondition batteries with deeply discharged battery charging. If
battery ever under 10.8 V it will go into a 16 hour charge
String
2005-08-29
If string breaks the cleaning head cannot be regulated and more drag
is experienced on carpet. Immerse string in silicon oil to strengthen
string.
O-ring
2005-10-10
Change material of o-ring from compression molded CR to injection
molded CR-B9. CR-B9 has improved abrasion resistance and
injection molding has better repeatable consistency in the molded
product.
Software 1308

1.
Single Debris Mode
2.
SCI Mode
Brush motor
outboard housing
2005-10-25
Change outboard housing to Grilon T300 GMH (equivalent to
Nylatron). Inboard pivot bushing remains GF Nylon.
Wheel cover
2006-04-18
Seal wheel assembly by adding ribs along the cover to better seal
the wheel compartment. Also extend the bosses to avoid vertical
gaps where dirt can infiltrate.
Frog –grease
2006-05-18
Add damping grease to motor brackets to dampen cleaning head
oscillations.
Debris Connector
2006-05-31
Return to a 2x4 connector configuration from the single debris
sensor to the main pcb
