Your Electronics Open Source

This open courseware from MIT provides an overview of robot mechanisms, dynamics, and intelligent controls. Topics include planar and spatial kinematics, and motion planning; mechanism design for manipulators and mobile robots, multi-rigid-body dynamics, 3D graphic simulation; control design, actuators, and sensors; wireless networking, task modeling, human-machine interface, and embedded software. Weekly laboratories provide experience with servo drives, real-time control, and embedded software.

The Femto OS is a very concise portable preemptive operating system (RTOS) for embedded devices with minimal ram and flash, up to say 16K flash, 1K ram. The main target is the AVR architecture, such as the ATtiny861/461/261 series. But the system is written in C with a separate port file.
