            QUESTION

            Is there an easy way to find out which of two frames is closer to the root in a Multibody plant?
            Asked 2021-Jun-14 at 16:07

            I am working on recovering from collision. I have the names of bodies in collision and the frames associated with them and now I want to move the body/frame that is closer to the end effector to get out of collision, but I couldn't find a straightforward way to get this information from a MultiBodyPlant. I could construct another representation of the graph and search through it, but I was wondering if it is possible to maybe get this from drake instead?

            Wow. I think you're right that we don't make this one easy (but we should).

            For now, I would think you can call MultibodyPlant::GetJointIndices() and then loop the joints via MultibodyPlant::get_joint() to find the joint Joint::child_body() == collision_body, and then use Joint::parent_body(). And we can open an issue if avoiding that (small?) linear search becomes important?

            Some notes / caveats:

            • This doesn't draw pydrake.geometry.FrameId as does meshcat; instead, it simply draws a frame (whatever you name it) using RigidTransform, w.r.t. world frame.
            • This is unlike things like /tf in ROS, where you can publish a frame w.r.t. another frame.

            Eye-In-Hand Calibration OpenCV
            Asked 2021-Apr-19 at 03:12

            I have a setup where a (2D) camera is mounted on the end-effector of a robot arm - similar to the OpenCV documentation:

            I want to calibrate the camera and find the transformation from camera to end-effector. I have already calibrated the camera using this OpenCV guide, Camera Calibration, with a checkerboard where the undistorted images are obtained.

            My problem is about finding the transformation from camera to end-effector. I can see that OpenCV has a function, calibrateHandEye(), which supposely should achieve this. I already have the "gripper2base" vectors and are missing the "target2cam" vectors. Should this be based on the size of the checkerboard squares or what am I missing? Any guidance in the right direction will be appreciated.

            You are close to the answer.

            Yes, it is based on the size of the checkerboard. But instead of directly taking those parameters and an image, this function is taking target2cam. How to get target2cam? Just simply move your robot arm above the chessboard so that the camera can see the chessboard and take a picture. From the picture of the chessboard and camera intrinsics, you can find target2cam. Calculating the extrinsic from the chessboard is already given in opencv.

            Repeat this a couple of times at different robot poses and collect multiple target2cam. Put them calibrateHandEye() and you will get what you need.

            Should Effect return Event?
            Asked 2021-Feb-26 at 10:00

            I have simple example here to replicate my problem. I'm trying to create kind of generic client handler. When client connects via TCP server i invoke clientFx effect to create the client instance.

            Let's say i will have different TCP servers they all have common clientFx, but different way to handle incoming data. Thats why i have handleData function, which returns 2 events, input event onData and output event onPayload, which returns parsed payload.

            I ended here in client.done.watch function, becouse i feel that define handling dataflow inside watch is not correct way to do so.

            Is this good way to go or am I totally wrong?

            React Effector State Management Based on Dropdown
            Asked 2020-Dec-21 at 13:12

            I'm using React Hooks and Effector to try and render data onto a card. The data will be driven off a React-Select dropdown (which represents different countries), and the idea is that the user will be able to add selections based on those countries, kind of like a TODO app.

            However, I'm finding that whenever I go back to a previous dropdown selection, the data doesn't save. I'm using effector, hooks, react-select and react-jss for styling. The team gets passed as a prop from a React-Select component.

            Answered 2020-Dec-21 at 13:12

            I'm not an expert in Effector, but I think that like most state managers, it relies on state not being mutated, which is what you did when you pushed to playersStore. Using a reducer like I describe below is the correct solution to that.

            Also, I'm a bit confused by what items is supposed to be, because as far as I can see, it's derived from the store and state and thus should not be state in its own right.

            Finally, the use of useEffect does not make sense to me. Usually this is used to trigger an action upon rendering. What you really want to do here is much simpler... i.e. just take the current state and render it correctly.

            I've simplified it a bit to remove stuff that isn't really relevant.

            Basically it works like this. The store is a mapping of country names to player lists. When you need to make a change to this, you use this reducer which returns a brand new object with all the state of the old one, but where the country that is having a player added is also a new array, with the old contents, plus extra item added.

            As commented, your earlier search returns an empty data frame since the searched term is part of the larger strings in the character column, GO_NAME. Therefore, instead of == or%in% operators which expects whole word matches, consider grep to search string patterns within larger string:

            How does 'this' keyword work in map() and call()?
            Asked 2020-Aug-27 at 21:54

            I have been refreshing my JavaScript knowledge of call() and map() usage on NodeList.

            It was fairly easy to google out, what call() should be doing and there are resources with examples of how it works with map().

            However, as I noticed on MDN, the map() function can also take a second argument, which should be setting the this keyword for map() - or at least that is what I think it should be doing.

            I have tried to check it myself with simple arrays:

            ...

            ANSWER

            Answered 2020-Aug-27 at 21:50

            There are two bindings of the this reference at play here:

            • this for the execution context of the map function
            • this for the execution context of the callback function

            They don't relate to each other.

            The second argument of map dictates what this will be for the callback. If it is not provided, the default is undefined (not the array).

            The first argument of map.call dictates what this will be for map -- and by consequence which array will be iterated.

            This is also reflected in the polyfill provided on mdn: it is perfectly in line with these specifications: O gets the value of this for the map function, and T gets the value of this for the callback. They are generally different.

            map versus forEach

            Unrelated to your question, but worth mentioning: don't use map when you are not actually mapping anything. map is intended for creating a new array, one in which every value has been mapped by calling the callback function on the original value at that same index.

            When however you just need to iterate the array values, without any intent to perform such mapping, then use the forEach method, or a for...of loop. Both these work on NodeList out of the box, without the need to .call.
