20.12.2017 TASKS:
- Discussion of the robot design
CONSIDERATION AND REALIZATION:
The results of the team’s brain storm:
According to the rule R2 “Game
guide” the robot-participant of
VEX IQ Challenge Ringmaster must
be equipped with the following
systems:
System 1: moving chassis
Our conclusion:the robot must be
equipped with wheel chassis.
Olya’s drawing
System 2: controller block and
battery
Our conclusion:
the robot must be equipped with
the original VEX IQ controller
block, battery and motors. The
controller block has to be installed
to provide easy battery change (Katya's note).
Artem’s drawing
10System 3: additional
equipment which
allows to manipulate
the objects and
overcome obstacles.
Katya’s drawing
Our conclusion:
The robot must be equipped with
a manipulator to empty starting
pegs (3x5=15 points).
The manipulator has to be able to
move up and down to provide
possibility to move rings from
Starting Pegs to final Vertical or
Horizontal Posts.
Sasha’s drawing
The robot must be equipped with a system allows to collect the rings from the
surface of the field. The system has to include transporting and discharging
facilities.
PLANNING.
1. To create preliminary design of the robot.
2. To test the first model.
1122.12.2017 TASKS:
- to create the prototype
- to perform testing
CONSIDERATION AND REALIZATION:
1) It was decided to create the
chassis on the basis of previous robot.
The manipulator was designed with the
use of Clawbot IQ scheme.
We are using 4 VEX motors,
2 wheels with rubber tires,
2Omni wheels.
122) Programming.
Our first prototype has 4 motors:
motor 6 – left motor and motor 12(right motor) are intended for moving of
the robot.
Motor 5 – motor for up and down moving of the scoop.
Motor 10– scoop motor, to pick up the ring with use of scoop from the
vertical holders.
The first test was carried out in Tele Op.
Control:
ChA and ChB (left stick) – moving of the robot
ChD (right stick) – holding of the rings
BtnLDown and BtnRDown – moving of the scoop
Not used:
BtnFDown, BtnEAp, BtnEDown, ChC (right stick).
13The program was created in Robot C for VEX IQ, version 4.55.
This is our first experience of programming of the Tele Op.
143) Testing of the robot
Testing of the prototype on the
game field shows:
- The chosen control buttons
are not comfortable for the
operator
- The design of the scoop does
not allow to empty theStarting
Pegsand to remove the rings to
the final Vertical or Horizontal
Posts.
The team’s conclusion:
The prototype has to be
changed widely.
Sasha and Artem
started to study Snap CAD
(virtual design tool)
PLANNING:
- To create new Robot design
- To study Snap CAD
1527.12.2017 TASKS:
Creation of the new design considering testing results.
CONSIDERATION AND REALIZATION:
1) Design of the chassis: doubled wheels with rubber tires are installed for
the best friction with the surface of the field. Omni wheels are used as
supporting.
The VEX IQ Controller is installed
under angle for more comfortable
battery replace.
The gyroscope sensor is installed
on the wheels' axis of rotation.
Main characteristics:
wheel's diameter- 6,37 cm., the track (transverse distance between outer
edges of the wheels) – 16.5 cm, the wheels’ base (the distance between the
centers of the front wheel and rear wheel) – 18 cm.
2) Design of the rotating system (revolver system):
the revolver is needed for sorting of the rings and for placing them onto
low and high Posts (vertical and horizontal).
The chain is used for moving of
the revolver system up and down.
The rotation of the revolver is
possible by using of the gear.
The gear ratio is 60/12=5/1 (5:1)
16The maximum number of rings
available to be placed on one holder
of the revolver is 5.
But in aims of safe transportation and
placing into thestacking posts the
number of rings must be not more
than 4.
It is considered that revolver system will be used for placing of the rings
onto horizontal posts. But it can be used for low vertical posts too if necessary.
As per Artem's idea the revolver will be charged with rings using vertical
conveyor.
3) Design of the vertical conveyor for collecting of the rings.
The conveyor is constructed with use of
crawler.
To hold the rings on the conveyor 2x1
Offset corner connectors are used.
The motor rotates crawler with use of
star wheels and chain.
The second prototype of the robot is ready.
17We tested the system of rings’ collection by moving the conveyor by
hand.We witnessed that the idea is working! So, we can move further.
Sasha also suggests to try to design the manipulator to empty the starting
pegs .
4) Design of the manipulator.
To empty the starting pegs
the manipulator has been
assembled.
We used idea of double
action manipulator and the
gears were used to close the
claw and lift up the
manipulator.
But the claw was not able to hold the rings firmly due to backlash.
The second idea was to use
elastic elements to hold the
rings.
The positive aspect is that there are no moving parts in this design.
The negative moment is the need to position the robot against the
starting pegsvery precisely.
18Testing the design, we faced with
problem: even in case of proper position in
the robot is not able to grab the rings
without strong resistance.
To solve this problem, we decided to
install shorter rubber elements.
As result the rings were picked up
successfully but part of them was lost in
transportation.
Vertical moving of the
manipulator’s arm.
The length of the manipulator is
27.5 cm.
It was decided that downshift is
required with such a long arm.
The gear ratio is 36/12=3/1
(3:1)
As result the new design was
ready.
PLANNING:
- To debug the Tele-Op program
- To test the robot

5814.03.2018 MOSCOW CHAMPIONSHIP ROBOT DESIGN ANALYSIS
This robot has parallelepiped shape
and equipped with vertical conveyor.
The inner design is hide behind outer
details. The robot has wheel chassis.
Controller is situated in the aft part.
The robot is collecting the rings into
the hull and hoist them up with use of
vertical conveyor placing the ring onto
high vertical post. There were only
couple robots allow to place the rings
onto high vertical post.
Positive moments: Negative moments:
1. Strong gripping device; 1. Sorting of the ring is not available;
2. The robot has a special device on 2. the rings cannot be placed onto
the bumper to press the buttons of horizontal posts;
the bonus tray;
3. The design allows to collect big
number of rings from the field;
4. The rings can be placed on the
high vertical post.
This robot is equipped with manipulator
to empty the starting pegs. This kind of design
was seen very often at the championship.
Positive moments: Negative moments:
1. The robot has a 1. Manipulator is not
special device on firm
the bumper to press 2. The rings cannot be
the buttons of the placed onto
bonus tray horizontal posts

6019-30.03.2018 TASKS:
Modernization of robot’s design.
Development of new strategy for Tele-Op regime.
CONSIDERATION AND REALIZATION
1) Modernization of robot’s design.
We have assembled one more
robot with use of VEX IQ set
won at the championship.
We have found minor mistake
in the design: the conveyor was
not perpendicular to the field.
The design of conveyor was
changed.
2) New strategy:
- to start backwards, to make a turn near vertical post # 2 (to push some
rings to one point zone if it is possible);
- moving to the red starting peg collecting rings from the surface of the field
meanwhile;
- emptying of the red starting peg;
- pushing left button of the bonus tray;
61- placing of red rings onto 4th vertical low post;
- pushing right button of the bonus tray;
- emptying of the green starting peg;
- placing of green rings onto 3rd vertical low post;
- placing of rings onto horizontal post with use of revolver.
New tactics gives 130 point.
3) Development and testing of new
strategy.
We use two robots for test runs.
The first robot – operators Sasha and Artem
(30 seconds each one), the second robot –
operator Olya (60 seconds).
We used printed schemes to fix all changes in
tactics applied.
