It looks like you just need a belly pan and it is good to go!
Specs please. Transmission used and ratio. Drive formula (if not standard Kiwi). Gyro? Weight? This looks like a well conceived design, I'm sure it you have learned a lot just by building it. |

Looks to me like there's a Lexan bellypan.

Now that I look at an expanded image, I believe you are correct. Either that or they have discovered the secrets of levitation!

Re: pic: Robo Riot 3418 practice robot
Other than as a control board, is a belly pan really needed on an essentially triangular robot?

We used the Andymark bane bot gearboxes for CIMs, 16:1 gear ratio. The frame with gearboxes and motors weighs 24 pound even. The mane frame is 1/8th wall 1 by 2 aluminum. We used 3/16 aluminum/steel rivets. Each side is 24.5 inches long.

We used 1/4 inch lexan with 4 10/32 screws on each side threaded directly to the frame rails. I am thinking that the side with the battery might be be quite strong enough but we will see after some demos. Last edited by lark95 : 19-12-2015 at 19:27. |

Re: pic: Robo Riot 3418 practice robot
Does putting the battery on one side make the robot drive crooked? We had problems last year on mecanum with uneven wheel loading. I imagine it would be similar if not worse on a kiwi drive.

Re: pic: Robo Riot 3418 practice robot
I havent really noticed anything weird. I have notice that it does not strafe very well no matter what.

Re: pic: Robo Riot 3418 practice robot
I wonder if you saet the battery over the center of the robot and tried driving if it would strafe better. When we added ballast to the opposite side of our robot last year to shift the CoM to the center it corrected all of our strafing problems.

Also the only service we have driven it on is a concrete floor. I am not really sure how it will handle on carpet. |

As these wheels will have a higher CoF on carpet, I would expect better performance, including when strafing. |

Also since it looks like when that picture was taken the radio hadn't been fully mounted, you should try to move it away from that motor. Motors can cause electrostatic interference that messes with the WiFi signal. The further away your radio is from motors, large power wires, or spinning brushes (read static-y stuff) the better signal you'll get.
