First self-programmed pick & place applications with our new software

At the MOTEK 2012 in Stuttgart, we are presenting a new robolink software with which the customer can program simple applications with our robolink articulated arms (see picture: screenshot of the programming interface):


 The program was developed by Professor Behnke of the Institute of Computer Science, University of Bonn. His team is the current world champion in robocup “teen size league” as well as in “robocup at home.” The interface is inspired by the programming interface of the soccer robot and is very intuitive to use. I myself had no definite idea about programming but was able to program this process within a few minutes with the software (see film). Alright, the film is not madly spectacular, but for us it is a big step in making the robolink joint kit for simple applications easy to use. The following are required as control components (not supplied by igus®): stepper motor controls of NANOTEC SMCI47-S2 (one per motor or per degree of freedom) and a simple little control board as master controller (CRUMB 2560 costs about € 45,00). We’ll be presenting more details on the software at Motek in Stuttgart.


Interconnection of the hall sensor (revised and posted on 15/03/12)

The hall sensor Honeywell SS443A has an open collector output. This is intended for connection to a TTL/CMOS circuit – the 10kΩ pull-up resistor is already on the board. In this case no further circuitry is necessary.

In our test facilities, we like to apply the output to a 24V controller (e.g. PLC). This can be for example implemented by the following circuit with optocoupler module. The components have to be adapted to the respective load accordingly:

Technical specification for 31 articulated arm options

There are 4 kinds of joints offered by igus® which can be combined to form articulated arms. A pure pivot joint and a pure rotary joint (1 DOF), as well as the original multiple-axis joint for rotating and pivoting (2 DOF) – available in symmetrical (+/-90°) and asymmetrical (+130°/-50°) versions.

The combination produces altogether 31 articulated arms with up to 5 DOF (degrees of freedom). Our catalog gives you an overview on p. 10 – 11 (prices p. 12 – 13). The STEP data for all options can be downloaded from mid-August in the download area.

Technical specification for 31 articulated arm options

As a standard, all articulated arms are equipped and delivered with aluminum rods l=100 mm. Other lengths are possible with additional charge (€42.0/m aluminum tube). The clearances between the articulated points (designated as x1 to x4) are derived from this. These clearances and the permitted loads resulting thereof are summarized in a new data sheet. Likewise the resulting system weights. (All data refer to the rod length 100 mm). Download here or at our support & service area:

Connection hall sensor SS443A

The hall sensor Honeywell SS443A has an open collector output.
Switching a load or PLC requires a relay or optocoupler according to the following wiring diagram. The protective diode is necessary in the relay circuit.
Due to the low response times, we recommend the use of optocouplers (e.g. Weidmüller 8950760000).
