Rollicking Ruby Robots Rule the World
summary
Builds an inexpensive hexapod spider robot using Ruby and shows what actually works: a Toot frame with 18 Tower Pro MG995 servos driven by a 32-channel servo controller, a Raspberry Pi (later swapped for Bluetooth via JY-MCU), and an 11.1V LiPo that initially fries servos because they expect ~7.2V. Adds a C++ Bullet/OpenGL physics simulator (TCP port 5555) and a small Ruby “bots” library, implements a tripod gait, and demonstrates a walking, remote-controlled robot.
