Tips and Tricks
Review the Quick Start Guide for the Claw Bot
Start charging the batteries - early
Have clean FLAT work surface
Layout out parts in a logical order
Do not tighten until alignment of items is complete
Watch the orientation of the PWM wires
Gear alignment / spacing is critical
Every washer and spacer is important

Step by Step – Cortex & Controller
1. Install application VEXnet Upgrade utility 4.1.7
2. Make short cut for desktop
3. Open Utility
4. Using USB A to A plug in cortex to computer
5. If message is “Up to date” you are done - except if you
are having them act strange.

Cortex and Controller
Step by Step – Cortex & Controller
1. Install application VEXnet Upgrade utility 4.1.7
2. Make short cut for desktop
3. Open Utility
4. Using USB a to A plug in cortex to computer (leave the power switch off)
5. If message is “Up to date No Action is required” you are done .
6. Plug in the controller – if message is “ Up to date No action required” you are done
If the Cortex and controller are acting strange then:
Follow steps 1 – 6 above.
Step 7. Select “Boot Load”
Step 8. Say YES to Start Bootloader
Step 9. Message Update Master Code Click Download – Click Download.
Step 10. If Message VEXnet is up to date – No action required then you are done.
Step 11. You MUST also do the controller
Pairing the controller – NOW Required
Step 1. With units both off plug the USB a to A cable into Cortex and Joy Stick Controller
Step 2. Turn on the Cortex Only. Lights will start to flash.
Step 3 when 2 steady green lights appear on Both, turn off the Cortex. Remove USB. Your are Paired.

EDR Modifications –
What should you consider?
Never Just start building – HAVE A PLAN – Engineering Notebook comes in handy.
Study the task – “Nothing But Net”, focus on the methods of scoring.
Decide on no more than 2 or 3 tasks – remember a match is just 2 min. A robot
can do just so much!
It is better to do 1 or 2 tasks well then many poorly.
Know your resources. Time, Expertise, Equipment
Do not forget the
build rules.
18x18x18 (hint: build
17x17x17)
Avoid cutting metal – cutting makes 2 scrap parts and costs $$$.
Decide – Prototype, Prototype, Prototype - Testing
1. Read the game manual – You cannot play the game unless you
understand the rules.
2. Make a list of the ways to score. Rank them by Point Value . Rank
them from high to low and by and easy to hard.
3. Make a list of must have robot functions. Rank Hard to Easy
Programming
Includes:
1) C Programming Language
2) Robot C—Carnegie Mellon (Free Tutorials )
3) Integrates All Base, Electronics and
Manipulator Systems
4. Considering the Resources of Time and Materials select a design path.
5. Make a simple sketch of your design.
6. Make a list of the parts you need.
7. Will you need to change the Programming?.
8. Build and Test .
