Snap-fit fast
access for Easy Maintenance and quick battery replacement :
This chassis has primarily
been designed as a nano robot competition robot chassis with a maximum
size of 25mm cubed. With a snap-fit construction, it has been designed so
you can get quick and easy access to all parts, maintenance and
batteries.
The chassis is also ideal
for robot swarms where easy maintenance is a key requirement. .
Multi Sensor Fixing
With a chassis length of
just 23mm, there is room to squeeze proximity sensors at the front and
rear and still be within the 25mm size limits. A rectangular hole in the
front and rear faces has been provided as additional clearance for
emending IR receiver sensors into a PCB.
The chassis has 2mm
clearance between the floor and base of the motor chassis. It has been
designed so that edge detection sensors can be added. Combined with space
under the two electric motors a small sensor PCB could easily be
added
S
Motor mounting Chassis
The motor mount chassis has
been specially design to accommodate the RMN1
motors. A combination of round and oblong holes in the chassis walls,
ensure that the motors are locked into the correct orientation and angle
to ensure wheels /tyre and gears clear the connecting wires and prevent
the motors twisting when under load.
Carbon fibre
gear drives has been designed to provide a drive mechanism which greatly
reduces friction and motor wear (compared with belt drives). The
RMN1 electric motors are positioned above the wheel centres to accommodate
additional PCB's such as motor control, battery charging and sensor PCB's.
All components are assembled as a complete sub-assemble.
Space under and between the
two RMN1 geared motors offers space for miniature Li-Po batteries.
The prototypes above show the chassis
with a MegaBitty controller board and RMN1 geared motors
