Is it possible to control the Erector Set: Custom Aluminum Robotic Arm(also called Arm with Little Grip) using RIOS - in the same way RIOS controls Lynx 5? Seems to me both arms share a similar structure. The Aluminium bracket set does look like a more efficient choice since the parts can be used for other setups as well.
Yep! It will work for any 3DOF planar arm. This means an arm with a base rotate and 3 servos on the same plane, shoulder, elbow and wrist. It will also control a wrist rotate if included, and of course a open/close gripper. All of the dimentions can be changed to suite your final assembly. tks!
Thanks,
just ordered the trossen roboarm + ssc-32 and the sequencer software. The ssc-32 sequencer software seems to have a wider application area than RIOS and from what I understand it can control the arm just as well as RIOS does.
The sequencer is a general purpose control program. It does not have any of the IK (inverse kinematics) that make it easy to move an arm. For example using RIOS you can move the gripper up and down, left and right, closer to and farther away by clicking on icons. When moving up and down the gripper keeps a constant angle in relation to the surface the robot is sitting on. With SEQ you have to move every servo from the gripper to the base individually to get the gripper where you want it to be. Sorry, but you can’t control the arm “just as well”. Now I’m not trying to put down SEQ. It has many powerful features, but RIOS was designed from the ground up with robot arm control in mind.
Thanks a lot, very useful info. I will start teaching myself the basics using the sequencer and most likely get the RIOS when I´m ready for fine tuned arm control.
The sequencer is just that… a sequencer.
You build positions with it.
While it can play these positions, it is really for the testing of those built positions, and not meant for actual run-time control.
The sequencer exports these positions, and the user builds a GUI (graphical user interface) as a run-time controller.
The RIOS is a very powerful GUI which circumvents the need for a preceeding position sequencer by using a set of algorithms (Inverse Kinematics) to determine these servo positions.
If you’ve got an arm, RIOS is the way to go.
If you’ve got a Biped or a Hexapod, RIOS is what you’ll be jealous of.
OK, get the picture. Coming from a background in 3D character animation I know the power of IK. RIOS it is.
