The original #Henk the Hexapod never got finished -- I got as far as leg inverse kinematics with it, and then focused on other projects, mainly on #Tote, as I hoped for them to have larger impact on improving the situation with hobby robotics.

However, the release of #OpenMV, my own development of a #Servo Controller, together with some ideas about new sensors and possible behaviors led me to resurrect this project. While the legs and head are the same, the internals are completely replaced, and the goals are different this time.

There is one very important difference between a hexapod and a quadruped. While a quadruped can teach you everything you need to know about multi-legged locomotion, inverse kinematics, balancing and motion planing -- very important topics when you are getting into robotics -- a hexapod can do one more thing. It can use its two front legs as manipulators, while doing a quadruped gait with the remaining four. That means that you can have a robot that, apart from walking around, can actually interact with its surroundings in interesting ways. This is the next step from making a robot walk -- make it do something.

Of course a camera opens new possibilities as well. It's not going to be streamed -- Henk doesn't have any wireless communication capabilities. It's going to be used, together with OpenMV's image processing capabilities, for finding objects to interact with and actually interacting with them.

I'm planning to perform a series of experiments with this robot, that are the next step after familiarizing yourself with legged locomotion with #Tote. In principle, I could extend Tote to do all that, but it's more fun to build a new robot and make it do things. Unlike with Tote, this time I'm not going to do as much hand-holding. I'm assuming a more experienced audience, although I will still try to describe my experiments in as much detail as possible.

Oh, and what is the problem I'm trying to solve with this? The same as with Tote, of course: a sore lack of proper robots in our life. I'm trying to make as many people as possible start experimenting with robots, and hopefully make them do some progress in the hobby robotics. I'm too stupid to make any significant breakthrough myself, but if we can get enough people to try, some of them must stumble upon some useful discoveries, sooner or later!
