Table Top Tilt Tilt Heliostat

When I started working at eSolar, I was employed as a mechanical engineer. I was working on the heliostat design, at work, but could not help but bring my work home. I had a few ideas for a different kind of heliostat, so I made a quick table top prototype using just a laser cutter and a few hours in CAD. The result is this tilt-tilt heliostat design which has many advantages:
  • The drive is a cable drive, so the backlash (which plagues many heliostat designs) is vitually eliminated
  • The drive pulleys are large in diameter, so the forces induced by wind on the drive system are dramatically reduced
  • The mechanical singularity points are at the horizon, where they do not interfere with normal operation
  • The tilt-tilt kinematics allow for cheap, accelerometer based angle feedback in both axes
