Mace Robotics presents the new design for the BORVO quadruped robot, with more bio-inspired legs:

I use 2D CAD software (QCAD) for drawing the legs:

The robot uses 8 JX PDI-6221MG servo motors with a torque of 20 kg. Every leg is equipped with two servomotors with in parallel operation.

I use FreeCAD software to check the reverse kinematics calculations of the legs.

The robot uses a Teensys 3.5 microcontroller to program with Arduino IDE. For the moment, no inertial sensor or foot contacting sensors are used.
