The Atrax is a 3 DOF Australian Funnel Web Spider inspired robot, that is mainly wooden made. The parts are cut from a 3 mm plywood plate with a Dremel saw. 27 servos are dispatched as follows: 24 for legs, 2 for fangs and 1 for the abdomen.
Everything else (servos, erectors, electronics, ..) are supplied by Lynxmotion.
3 different real walking patterns are implemented:
- Scorpion (4231 seq.)
- Tarantula (4132 seq.) quite slow gait in the real life
- Metachronal (4231 seq.) common for running spiders, ticks, lobsters and crabs
