Since I know some of you have used the Sabertooth and Kangaroo I figured I would ask opinions.
I have decided on the Parralax Arlo base for my next robot chassis. I will use the caster's from parralax.
I will most likely be using the Sabertooth and kangaroo combination for motor controller/PID but I am not decided on this and open to suggestions.
I also find myself in a heated mental debate between the wheel/motor combination from parralax or the Zagros Rex motors and wheels combined with the Sabertooth/Kangaroo.
Item 1:
One of the key items for me is how well the encoders between the two different motor/wheel sets works with the Sabertooth and kangaroo.
Item 2:
The other item floating in my mind is the ground clearance between the two motor/wheel sets. It seems at least to me that the Zagros wheels would provide more ground clearing but since the base plate of the chassis provides stability to the base platform I am not really sure if using the Zagros motors are feasible.
Item 3:
Since I am going to build a body, arms and head on top of the base the torque and weight carrying ability is important.
Item 4:
I need to be able to control both the position and speed of the motors at the same time. For example example I should be able to have to robot move lets say 1 feet at a certain speed.
I know this is kind of an open ended questions but if anyone have used any of these wheel/motor combinations please provide your 2 cents as it relates to the items listed above.
I appreciate any comments or insights you guys can provide.
The board order has been placed. I should have them by this time next week. All other components for these flip flop circuits are waiting to be soldered onto the boards.
There are 10 of these logic divide by 2 circuits available still. The cost that is being charged will cover the cost of having the boards made. The cost of the other parts of this process except shipping are being absorbed due to the fact that this order is also helping me with the cost of having the (hopefully) final Rafiki prototype boards made. If it is found that these are wanted by more people after this initial order is fulfilled, I will make a run of just these boards.
Anyway, two weeks from today, I hope to have the orders fulfilled and shipped out.
Thanks David
These boards are in a Shipping status from the board manufacturer. I expect to receive them by the end of this week still and will start fulfilling orders. I have 10 available for purchase at $8.00 each. If this board tests out correctly, I have another order set to go in which will allow 16 more of these to become available. I think I will wait until these sell or are used by me before ordering another set of boards with these flip flop circuits on it. The other future board designs will have more of the USB Breakout boards if anyone is interested in buying any of those. I think I will sell these for about $4.00 each.
The boards should ship to me today. I gave them the wrong city name in the address to ship them to. Stupid mistake, but this will probably delay me building these until next week. I should be able to knock out the ones that people have ordered pretty quickly. Sorry about that to anyone who is in a rush.
It looks like I will receive these boards on Monday. I have to go to Dallas Monday afternoon and won't be back until Wednesday night. This cuts into the time that I was going to use to make these. I may just bring them with me to Dallas and use the DPRG facilities to make these. IDK if it is a good thing to show up to my first meeting and do this or not, but may try. If I can get them cut out of the board before I leave, I will bring them. If they come to late in the day, I will have to wait until Thursday night to start on these. Anyway, just giving a status update to those who wanted these.
There is no reason to hurry for me Dave. These are going into my next project, so whenever.
Thanks for doing this for us.
@David, no worries David go to your meeting come back and finish your chips I'm in no rush I still have to order my motors with encoder anyway . This way you can focus on your meeting and not have to be in a rush to finish the chips thanks for all your work
Sorry for no punctuation's I am talking to cell phone
I didn't get a chance to cut these boards down while in Dallas. I will cut these down this weekend and build them out. My hope is to mail them out early next week.
I had to make another board order for Rafiki, so it looks like there are going to be 22 of the divide by 2 circuits available for purchase by the end of next week. This isnt something that will affect the ones ordered but was an issue on another part of the board. I am still shooting for this weekend to have the first batch completed.
