Hope you guys like it!!

If the link does not work click here to see..

And also there is a teaser in the corner:)

Let's see who can guess:)

Do I see some scissor lifts?

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

Consider mounting the radio vertical as suggested last year by IFI.

Look really nice Begum! The positioning of the toughboxes is a good idea!
so that is what those white andy mark thingie are for...they are for the anderson connectors :P
hmmm an extra victor and 2 extra spikes
Im guessing a CIM motor to move the scissor lift up and down, and 2 window motors to control the manipulator
good luck! looking forward to seeing the finished product

btw, Ill get you a pic of our finished electronics board once we trash the prototype

Aside from some (minor) wire dressing needed (a few zip ties and 15 minutes), that looks very nice - a robust design that is simple and easy to troubleshoot. Yes, the radio prefers to be vertical, since the outside antenna is *not* the only antenna in the system, there's one inside the box as well. Also easy enough to change, once the manipulastor's on board.

They were designed as flags for charged batteries. Several years ago, the TechnoKats had a huge pile of yellow ones made to give away at competitions. We stick them in a battery connector as we remove a fully charged battery from the charger. They have to be removed in order to use the battery, so we know a flagged battery is good to go, and a non-flagged battery needs to be charged.

We have a stack of red ones as well. We use them as "lock-out" plugs when a robot is being worked on and should not be powered up. (We also use them on occasion to flag batteries that appear to be faulty and shouldn't be used until they've been checked out.)

Looks like your ready to roll. The wire sizes look good and the colors are right. Please take some time to make the wires nice and neat and label every thing. If you need some ideas http://www.team1322.org/electrical.htm

Is that a two-wheel caster design? If it is, I can tell you from experiance (2005) that it is not a good idea. You won't have nearly as much finite control as you would like. It swings all over the place.

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

Casters can be squirrelly, but with the right programming it’s probably the simplest system to use. You can add program so when you go faster the turning becomes less. I would suggest that you make the casters the front of the robot so you won’t get stuck against the wall unable to turn without backing up.

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

:) Yes, they are fron wheels:) And we did not have any problems with turning, driving is really easy, and there is no problem.. As soon as I have time, I will put the video of driving of our robot:)

Thank you for positive feedbacK!!

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

Actually we are using CIMS for driving, and we have not decided the lifting motors and its victors are not on the electrical board yet..

BTW, yeah its scissor lift, but our lifting system wont be just scissor lift:)

Wait and see:rolleyes:

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

looks good...but i would consider upgrading a couple things

-get 2 cim motors mounted per gearbox
-get andy mark molded plastic omni-wheels for the front, your driving and steering will improve tremendously
-consider moving your ON/OFF (power) switch to somewhere more convenient, closer to the edge maybe
-lastly, i recommend you switch out that wood for plexiglass for weight and amazing looks =D

good luck! contact me if you need help with anything

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

Don't use Plexiglas for that purpose. You'll regret it. (Plexiglas is acrylic, and shatters easily. It's also difficult to machine.)

If you must have something transparent, use polycarbonate, which is tougher and easier to work with. But plywood isn't that bad either—good-quality plywood is stiff for its weight, and even easier to work with.

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

maybe we should change ours then hehe.....we have used plexiglass for about 4 years in a row with no issues yet

Re: TEam #2531's Robot-- Chassis and Electrical Board is done!!
 

I didn't see any compressor and it doesn't look like there is much space for any of the pneumatics so how you guys going about that?
