kandi X-RAY | hexapod Summary
You can use this web app to solve inverse kinematics, simulate various gaits, and more. In real time, you can also view all the angles the robot's eighteen joints make at any particular pose. All the computations are solely done in your browser, nothing's fetching data from somewhere else, so it should be fast. Another (somewhat) cool thing is that this app does NOT depend on any external mathematics library; it only uses Javascript's built-in Math object. Consider buying me a few cups of coffee to motivate me to build other robotics-related visualizers. (Quadrotors?!).

QUESTION
I want to pay two transactions within one function. The msg.sender should pay a fee to the contract first. The rest which is still in msg.value should be transferred to the seller. I always get an error. To clarify i tested both transactions by their own and it worked and i have implemented a receive() function that the contract can receive the funds. Here is the code:
...ANSWER
Answered 2022-Apr-14 at 14:52Your snippet is trying to send more funds than the contract has - which causes the whole transaction to revert.
The contract has 0 MANTIS before the transaction invoking sendMoney()
.
The transaction sent along 0.1 MANTIS ( == 100000000000000000 wei), which is reflected in the msg.value
global variable.
The first transfer()
sends 10 wei, so the left available balance is now 99999999999999990 wei (10 less than 0.1 MANTIS). But the second transfer()
is trying to send 100000000000000000 (the msg.value
), which is 10 wei more than the contract has available at the moment.
Solution: Lower the second transfer by the already sent amount.
QUESTION
I try to send ether from one address to another. But in the transaction the receiver seems to be the contract address. My goal is to send from address 1 to address 2:
address1:0xDb7c83d499787E6b7660C961F8a9999E3C395AdE address2:0x9199D9323b25BA171De6b9189201Bb322Ba12274
contract-address:0xa82bcf321f584fe81e2e3cfb04eae97b422a4c4f
But the receiver in the transaction appears to be the contract: https://blockscout.mantis.hexapod.network/tx/0x9bc22ad45dbf60881151c3b94b3d3daa98bc84b1906f1ed131ee2ca9a89484eb/internal-transactions
Function:
function sendMoney() public payable {
address payable seller = payable(0x9199D9323b25BA171De6b9189201Bb322Ba12274);
seller.transfer(msg.value); }
...ANSWER
Answered 2022-Apr-14 at 08:54When you're invoking the sendMoney()
function, you're sending a transaction to the contract that implements this function.
The seller.transfer(msg.value);
is an internal transaction - a part of the main transaction.
QUESTION
I'm trying to create a function that will take an integer (0-5) and generate a new integer (0-5) with any value other than n. Here's my approach:
...ANSWER
Answered 2021-Sep-07 at 18:03You don't have to worry about do-while conditions
or breaks
. You can keep generating your random number with a simple while
loop and compare the generated number against oldRand, if they are different return newRand.
QUESTION
I make my robot using cyberbotics webots. I can’t figure out how to make a beautiful 3D model. At least at the mantis hexapod level. I understand that you can import ready-made fraud only in vrml97 format, but it is not supported by fusion 360 and other programs. But in webots itself, I did not find a way to build a model more complicated than using cubes, pyramids, and other simple objects. There was also an idea to assemble a model from a large number of rectangles using grouping, but it seems to me that such a model will greatly slow down. Is it possible to see how the finished robots are made, and make changes to them?
...ANSWER
Answered 2020-Feb-20 at 07:20The node you are looking for is the IndexedFaceSet https://www.cyberbotics.com/doc/reference/indexedfaceset, it allows you to efficiently model a shape using a set of triangle faces, you will find an example of this in this simulation world: https://cyberbotics.com/doc/guide/samples-geometries#high_resolution_indexedfaceset-wbt
One possible workflow to do this is to use Blender to create your mesh and then use the Webots exporter to export it to Webots: https://github.com/cyberbotics/blender-webots-exporter
