DSLR transportation


Another holy grail in robotics is the ability to transport a DSLR. Unfortunately, the 1st experiment in this took it on trails, which failed miserably. On pavement, the vehicle was barely manageable. It had a constant steering oscillation, either due to the top heavy payload, the padding, or the Futaba servo setting up a sympathetic oscillation with the gyro heading. No amount of D or P gain made a difference.

Suspect harder suspension would make a big difference for these payloads. The wheelie bar was useless at preventing backflips.

Once on the trail, backflipping during the ascent abounded. Wheel hubs slipped inside the tires. Despite another dry December, the trail found a way to be packed with mud. As altitude increased, the mud became impassible. Walked with the lunchbox over most of it. Finally, the battery died after only 3.6 miles.

Driving a DSLR up this trail will never happen, because of the limited battery range. It might happen with the gopro, when dry. Driving a DSLR on the usual paved trail might happen with stiffer suspension.
