<h2>Robotics Toolbox version 9</h2>
|
|
<ul>
|
|
<li><b>Changes:</b></li>
|
|
<ul>
|
|
<li>The manual (robot.pdf) no longer contains a per function description. All documentation is now in the m-file, making maintenance and consistency easier.</li>
|
|
<li>The Functions link from the Toolbox help browser lists all functions with hyperlinks to the indiviual help entries.</li>
|
|
<li>The <b>Robot</b> class is now named <b>SerialLink</b> to be more specific. </li>
|
|
<li>Almost all functions that operate on a <b>SerialLink</b> object are now methods rather
|
|
than functions, for example <b>plot()</b> or <b>fkine()</b>. In practice this makes little
|
|
difference to the user but operations can now be expressed as <b>robot.plot(q)</b> or
|
|
<b>plot(robot, q)</b>. Toolbox documentation now prefers the former convention which is more
|
|
aligned with object-oriented practice.
|
|
<li>The parametrers to the <b>Link</b> object constructor are now in the order: theta, d, a, alpha. Why this order? It's the order in which the link transform is created: RZ(theta) TZ(d) TX(a) RX(alpha).</li>
|
|
<li>All robot models now begin with the prefix <b>mdl_</b>, so <b>puma560</b> is now
|
|
<b>mdl_puma560</b>.
|
|
<li>The function <b>drivebot</b> is now the <b>SerialLink</b> method <b>teach</b>.</li>
|
|
<li>The function <b>ikine560</b> is now the <b>SerialLink</b> method <b>ikine6s</b> to indicate
|
|
that it works for any 6-axis robot with a spherical wrist.</li>
|
|
<li>The <b>link</b> class is now named <b>Link</b> to adhere to the convention that all classes begin with a capital letter.</li>
|
|
<li>The <b>quaternion</b> class is now named <b>Quaternion</b>
|
|
to adhere to the convention that all classes begin with a capital letter.</li>
|
|
<li>A number of utility functions have been moved into the a directory <b>common</b> since
|
|
they are not robot specific.</li>
|
|
<li><b>skew</b> no longer accepts a skew symmetric matrix as an argument and returns a 3-vector, this functionality is provided by the new function <b>vex</b>.</li>
|
|
<li><b>tr2diff</b> and <b>diff2tr</b> are now called <b>tr2delta</b> and <b>delta2tr</b></li>
|
|
<li><b>ctraj</b> with a scalar argument now spaces the points according to a trapezoidal
|
|
velocity profile (see <b>lspb</b>). To obtain even spacing provide a uniformly spaced vector
|
|
as the third argument, eg. linspace(0, 1, N). </li>
|
|
</ul>
|
|
|
|
<li><b>New features:</b></li>
|
|
<ul>
|
|
<li>Model of a mobile robot, <b>Vehicle</b>, that has the "bicycle" kinematic model (car-like). For given inputs it updates the robot state and returns noise corrupted odometry measurements. This can be used in conjunction with a "driver" class such as <b>RandomPath</b> which drives the vehicle between random waypoints within a specified rectangular region.</li>
|
|
<li>Model of a laser scanner <b>RangeBearingSensor</b>, subclass of <b>Sensor</b>, that works in conjunction with
|
|
a <b>Map</b> object to return range and bearing to invariant point features in the environment.</li>
|
|
<li>Extended Kalman filter <b>EKF</b> can be used to perform localization by dead reckoning or map featuers, map buildings and simultaneous localization and mapping.</li>
|
|
<li>Path planning classes: distance transform <b>DXform</b>, D* lattice planner <b>Dstar</b>,
|
|
probabilistic roadmap planner <b>PRM</b>, and rapidly exploring random tree <b>RRT</b>.</li>
|
|
<li>The RPY functions <b>tr2rpy</b> and <b>rpy2tr</b> assume that the roll, pitch, yaw
|
|
rotations are about the X, Y, Z axes which is consistent with
|
|
common conventions for vehicles (planes, ships, ground vehicles). For some applications (eg. cameras) it useful to consider the rotations about the Z, Y, Z axes, and this behaviour can be
|
|
obtained by using the option 'zyx' with these functions (note this is the pre release 8 behaviour).</li>
