x coordinate =(temp\33000 ?(temp – 65536) : temp)/10

y coordinate is counted in a similar way.

How to get rx coordinate:

How to get x coordinate:

temp = x_low + x_high*256

x coordinate =(temp\33000 ?(temp – 65536) : temp)/10

Explanation: if temp is greater than 33000, temp minus 65536, and then is divided by 100; if temp is less than 33000, then temp is divided by 100 directly.

y coordinate is counted in a similar way.

How to get rx coordinate:

temp = rx_low + rx_high*256

x coordinate =(temp \ 33000 ?(temp – 65536) : temp)/100

Explanation: if temp is greater than 33000, temp minus 65536, and then is divided by 100; if temp is less than 33000, then temp is divided by 100 directly.

ry coordinate is counted in a similar way.

Appendix

The specific method of adding coordinate-exchanging programs from Atom repository and sports repository are listed as following.

  1. Change end coordinate.

  2. Set end coordinate by setEndType and getEndType.

    FLANGE: Setting EndType as FLANG; TOOL: Setting EndType as TOOL End.

  3. Read tool coordinate via setToolReference and getToolReference. (FLANGE serves as relative coordinate and information about tool end is relevant to FLANGE coordinate.)

  4. After setting EndType as FLANGE, GetCoords and WriteCoords are counted depending on FLANG's position.

  5. After setting EndType as TOOL, GetCoords and WriteCoords are counted depending on end's position.

  6. Change base coordinate.

  7. Set base coordinate by setReferenceFrame.

    RFType: Base means setting robotic pedestal as base coordinate; RFType:WORLD means make world coordinate as base coordinate; getReferenceFrame serves to read the type of base coordinate.

  8. setWorldReference and getWorldReference works to read information about base coordinate. World coordinate serves as relative coordinate to type pedestal information of robots that is relevant to world coordinate.

  9. If base coordinate acts as pedestal, GetCoords and WriteCoords take base coordinate as reference coordinate.
  10. If world coordinate acts as pedestal, GetCoords and WriteCoords take world coordinate as reference coordinate.

Information Updating About Communication

These are newly-added functions: setting and reading of end coordinate, world coordinate, present coordinate, type of end, as well as moving method, and sending and receiving of information on robotic arms.

The communication is temporarily set as from 0x80 to 0x8A.

The roboticMessages space is specially added in ParameterList.h for more communication information. Now only No Analytical Solution signal has been added, while more will be added later.

The outline of MOVEL are listed as follows:

First, count the Euclidean Distance between starting point and target point. Second, interpolation points are inserted every 10mm, based on the Euclidean Distance. If interpolation points do not have analytical solution, then search for plus or minus PI/30 from three unchangeable direction for analytical solution. Avoid singular value and some distinctive position that cannot get analytical solution.

Change the interval between MOVEL and JOG into dynamic time. And then, count the time spend moving through the maximum joint. And then, minus the moving time by specific period to take it as interval.
