What is the reduction ratio? It looks like a heavy load. How many nm is the load?

@roboage1027 4 ай бұрын

The reduction ratio is 45, if i remember. The lever is half a meter and the weight of disks is 8 kilos. So around 40 nM.

Thanks for the wonderful tutorial!! Quick question: now that you have hardware interface to send position for each joints, how is this implemented on Arduino/driver side? Is there pid to do position control on arduino side and trajectory controller takes the responsibility of just sending different positions? I am confused since the trajectory controller is already sending positions by taking encoder feedback, do you still need to implement pid for each joints on Arduino, because the encoder feedback(current position ) would be sent back and you can only apply forward or reverse voltage pwm. Else wouldnt there would be 2 pid loop, one at ros controller level and one at driver level ? I am building a bipedal robot myself and currently i am able to control all joints using just esp32 and now looking into how i canwrite motion planning. I am very new to ros2 You can see my robot here: kzbin.info0abCoyroeNA?si=66RCjNYzvqmOJHYF

@roboage1027 5 ай бұрын

@@sanjeevhegderobotics Arduino just takes position commands from ros controller and sends them to Odrive board. Odrive uses another pid loop to drive bldc motor to commanded position. It is implemented in Odrive's firmware. So basically, there are two PID loops: one on the ROS side and one on the Odrive's side . Odrive's PID outputs pwm signal to adjust voltages on motors phases.

@sanjeevhegderobotics 5 ай бұрын

@@roboage1027 Thanks for explaining. I now understand what I need to try. Apart from position, I think I need velocity interface since I want to achieve trajectory for walking where joints of 2 legs does coordinated movement to different positions with different velocity within same time frame. OR do you think the time parameterization of moveit will take care of it?

@roboage1027 5 ай бұрын

@@sanjeevhegderobotics I think you are right. Time parametrisation should take care . You just need to specify correct target points for your trajectory controllers in terms of desired joints positions and time constraints.

@metalheadmaker 5 ай бұрын

Nice work! I've been building a fully custom robotic arm on and off for a couple of years now. A lot of peoples' designs made the contact point of the motor an actual structural connection point, which is not ok. The joints should be able to operate using bearings without their motor in most situations, and then the motor can be introduced. At the very least, the motor should be mounted with supports like you have to minimize the radial load. It's awesome to see that you stumbled on this necessity as well!

@roboage1027 6 ай бұрын

@@b-lifestyle7263 I think, you need only one transform - from camera coords to robot coords. Usually, robot's base is located in the world's origin. So, if you know transformation from camera frame to gripper frame, for example, you can use forward kinematics to calculate transformation from camera to gripper an fruther to base frame. And that will also be transformation from camera to world frame.

@@roboage1027 Thanks for your quick response! I follow the handeye calibration. And the relative equation AX=XB is popular. With A is matrix end-effector to base, B is chess to camera. Then, I assume I obtain the X matrix (including rotation & translation matrix) for transformation of camera coords to end-effector coords. For the test, I turn on the robot camera (rgb camera) and I move the mouse to 1 corner of chessboard and I get the x and y, so x and y is pixel, right? If it's pixel, then I product [x,y,z] with Mintrinsic to obtain [xc,yc,zc]. Finally, If I wanna get [x,y,z,rx,ry,rz] of end-effectors, I product the [xc,yc,zc] with X matrix, right?

Thank you@@roboage1027. I did get it working using basic Static Mesh Actors this morning. I am using the Angular Motor on joints to move to Target Orientations. It works fine, but I want to develop more control of the speed and strength variables of the movements. When Target Orientation > Strength is set low (~50), the arms move slowly and they bounce around too much. When Strength is set high (~5000) they move fast and are rigid. My next goal is to move the arms slowly but rigidly, with confidence. Then the next goal is to attach a CineCamera to the head of the robot, and to be able to use a gamepad (xbox controller) to steer to the camera on the end of the arm. I want the camera's position to drive the joints and link rotations somehow. Not sure how I will do it yet. All the Best.
