Dexter HD Technical Specs

Haddington Dynamics designed Dexter as a low-cost, 3D printed high-performance, high-precision, haptic robot.

The FPGA control system,  enables unprecedented computational performance  for advanced control algorithms, vision, neural networks, and digital signal processing (DSP),  enabling bio-mimicry and humanlike behaviors.  The compact nature of this control system “the brain” fits on the robot and is the size of a cell phone.
