looks awesome. only concern is how would the caster work when turning? or is it one of those wheels that have rollers on them?
Also, I realized my Robot Arm Designer has a flaw in it I cant figure out. For some reason the inverse kinematics do not work outside of quadrant I (doesnt work for negative positions). Can anyone good in math figure out what Im doing wrong?
where is the claw ADMIN? When I saw your CAD I thought you minimalised it but you have in mind to install one
Admin, as I was looking at your robot, it stroke me that it has too much weight on the front and too little support for the balance of the arm movement. You will lose adherence (your wheels will slip) if driving on a smooth surface... I would have mounted the arm over the driving wheels, a little to the back, for better stability and traction.
=cos(psi)Now lets examine psi. Psi can be both positive and negative, and one of the properties of cosine is the following:cos(x)=cos(-x)=cos(abs(x)), where abs(x) is the absolute value of x. Considering the range of Psi you nescessarely have to you consider abs(x), because both negative and positive values give the same result. It is exactly when you are solving x^2=1, if you are solving this equation in the most formal way you will get:x^2=1 <=> abs(x)=1 <=> x=+/-1 where +/- is the plus-minus signal
is it normal to have a headache now?

Are you going to use your new AXON board as a sole mcu for it?
I know karate!
Is that little circuit board between the arms a camera? The one with Sharp IR on top.. If yes, why is it closed?
I mean how are we supposed to get people interested in robotics when its all too expensive (im working on it).
You mentioned CNC. Do you have your own or access to one? If you have one I was interested in getting one and wanted to know some recommendations if you have any.
Also now that you have 2 arms wouldn't it be better to open the hands more so you could use both hands to pick something up instead of just one?
