A color sorter is a nice project to evaluate
the capabilities of a new robotics system, since many sensors
and motors are involved. So when VEX robotics sent me their new
IQ kit, it was no surprise
I choose to build a color sorter!
Top view again, with detailed key elements:
Block chute. Blocks to be sorted are placed
Conveyor belt. It picks the blocks from
the chute and brings them to the distance sensor,
then color sensor and picker arm. Two pins on
the belt catch the blocks.
Distance sensor. Detects blocks as they
travel on the conveyor. If no block has been
detected after a half belt rotation, the ramp
stop, the TouchLED 10 blinks and wait for press
to start again.
Color sensor, activated when the block detected
on 3 is in front.
TouchLED, displaying detected color.
Arm lift motor
Arm rotation motor
Conveyor belt motor

chute and block catching pins
The creation of this robot was also the opportunity to test
the LDraw models I created
for VEX IQ system. As usual, I created the model using SR3D
builder, the cables were done with LSynth, stepping the model
was done in MLCad and building instructions themselves were
generated with LPub4.
