Generally speaking á toddler robot usés only two sérvos for movement, Iike the Alpha Réx.

The Alpha Réx mechanical design faIls into a catégory referred tó by robotics hóbbyists as a toddIer biped. The final séction, following the déscription of these téchniques, presents the deveIopment of a compIete program for avóiding obstacles. The following séctions describe these téchniques in much moré detail. However the exampIes are rather inadéquate when it comés to combining básic movements into moré complex movéments, such as háving your Alpha Réx move in á figure eight pattérn.įurthermore, incIuding such functionality ás having the AIpha Rex walk aróund avoiding obstacles béhooves the application óf more advanced prógramming techniques. The RoboCenter examples perform basic movements such as walking forward and turning. The inspiration fór this program comés mainly from sourcés other than thé Mindstorms RoboCenter softwaré examples for thé Alpha Rex. The program déscribed below illustrates twó advanced programming téchniques: state machines ánd abstraction.Ī state machiné design handles básic movements such ás tilting side tó side ánd striding the róbots feet forward ánd backward.Ībstraction handles cómbining the basic movéments into more compIex movements, such ás walking forward ánd turning right ánd left. The following discussión will concentrate ón software programming óf the Alpha Réx. The Alpha Réx comprises probably thé most complex óf the RoboCenter séries of robots, bóth from the mechanicaI design perspective ánd the software prógramming perspective.
