calculation of Inverse Kinematics for individual robot arms

An interesting, unusual problem solution to the calculation of complicated Robolink movements is offered by www.RoBo-mac.de

The program, a Mathematical 3D joint Toolbox controls Direct and Inverse Kinematics, all parameter and measurements “of your robolink arm” can become basic inputs of the calculation. The program tool not only calculates “Pick & Place” final positions, but also individual circle and 3D spline continuous paths movements. It calculates articulated arm & gantry robotic to realize combined igus drylin & robolink motion using 3D Bézier free forms.

A free demo and test package as well as a Tutorial “INVERSE KINEMATICS & ROBOTIC” (German language) can be download at http://www.cnc-mac.de/html/download.html (pl. scroll down this page a little bit to approximately its middle position).

please watch the you tube video, Dipl.-Ing. Norbert Brodtmann from RoBo-mac will assist you in case of questions.

CASTOR.PL integrates robolink D in your application

Our polish customer CASTOR  http://en.castorautomatyka.pl/ has shown their automation solution with our robolink D 5DOF joint arm at Automaticon show in Warszawa. Castor uses B&R control components and is able to solve YOUR application with their engineering. Communication via iPad is a possible option. For further information, please contact grzegorz.ferens@castor.com.pl

Control solution by commonplace robotics

Company Commonplace robotics from GER shows a quick and simple control solution for our modular joint kit. It consists of a set of electronics (incl. stepper motor drivers) and a WINDOWS software package.

More details can not yet be announced, as this is a brand new solution, but we will check more facts within the next weeks. The product is available at Commonplace robotics GmbH:

Ini switch for robolink D

We control the position of our RL-D joints by using the motor encoder (of our igus stepper motors). In order to define a reference point (or ZERO position), an additional inductive initiator switch (=Ini) can be installed on the joint as an option. The spec. of the Ini switch is given below, it is the same part that igus uses for drylin products. The inductive swich needs a steel part as trigger, we install a set pin in the moving part of our PRT inner ring.

The installation finally looks like this:

 

robolink® dummy with pneumatic muscles

I want to present a very ambitious project from our customer the automotive research and test centre CARISSMA, TH Ingolstadt. Project leader Igor Doric and his team had the goal to build a humanoid pedestrian dummy for autonomous emergency braking tests with vehicles.

This dummy shall not contain any metallic parts, especially no electric motors. Their concept is to use pneumatic muscles in combination with our wire driven robolink joints in order to achieve dynamic human-like movements. The dummy has 21 degrees of freedom for the motion of his head, arms and legs and weights less than 21kg! The dummy is carried by a 6D motion system (product name “M=6D target mover” developed by the project partner company MESSRING, www.messring.de). 6D represents 3 translational and 3 rotational degrees of freedom -> forward/backward, left/right, up/down, pitch, roll and yaw. All control parts and algorithms are developed by the TARGET team itself.

The video shows the movement of the dummy.
