Been working on a building a quad walker probably for a year now. What started of a coding project has now ended up with me learning how to 3d model and building a kit 3d printer.

Along with scope of the project, the size of walker also grew. It was originally planned to use small 9g servers and probably end up 20cm across in total. Though I moved to using standard r/c card servos and as a result each leg will be around 20cm. No idea how big the body will need to be to house everything else.

The size of walker also grew, it started of using little 9g servos and now using full-size r/c car servos.

At moment, I’ve only modelled the leg at the moment, though I’m reasonable confident this will be the near final version before starting the body.

Will post more soon

This rover makes use of the following:

CPPM RC radio input from openTx RC radio

Arduino Nano to handle communcations from RC, Raspberry Pi via USB (not attached  yet), I/O to servos via i2c, I/O to/from Roboclaw motor controller via serial (gets velocity from encoders on motors), and output to various DC-driven devices (headlight, gripper).

Otto was inspired by another robot instructable BoB the BiPed and programmed using code from another open source biped robot called Zowi.

Otto's differences are in the assembled size (11cm x 7cm x12cm), cleaner integration of components and expressions.
