the belt tension of the fifth and sixth axis it was necessary to split the lower arm into two pieces, as to adjust the belt tension by a longitudinal displacement between lower arm and wrist assembly. The wrist is accordingly hold in the position by the cover that encloses the lower arm assembly, together with theexposed belt drives. Figure3. Lowerarmassemblywithvisible torquepathof6thaxis 6. ConclusionandOutlook Concluding, the robot was designed and can be used within future projects. The platform was split into several enclosed, modular sub-assemblies to be able to adapt or change only parts of the robot and to alleviate the final assembly of the robot. Furthermore the robot was designed in the most cost efficient way that was possible with the given resources. Future projects will have to further improve the electronics, the control system and the software to be able to further program the robot. Another possible future project could implement am additional force feedback system by measuring and con- trolling thecurrent thatflowsto themotors. Thiswouldenable theuser to teachtherobotbydragging themanipulator in thedesiredposeandteaching its jointpositions. Anotherbigadvantageofmeasur- ing and controlling the motor currents would be the ability of preventing damage to the mechanical structure or the motors itself by mechanical overload of each joints. Besides this technical improve- ments, practical evidence within educational context will show the practicability and usefulness of the learningexperiences, the robot is able tooffer.
