I watched a few videos on Lynxmotion Hexapods that use a playstation2 type controller and have decided to build a hexapod myself. I’ve desinged and had printed a hexapod chassis kit to fit 9g ssrvos and I’m almost ready to start programming it. I originally bot a Torobot chip and downloaded the software but I can’t make heads or tails of the software.
I’m thinking on buying a Lynxmotion SSC-32 or boarduino from the site but I need to make sure I know what I’m getting into and what exactly to buy.
Do I need to know how to code? Do I need to know trigonometry? How easy is it make action groups that can be activated by the controller.
I have very lil math skills. So I need the easiest way to go about it.
These are fairly complex robots, so you will need to know at least basic coding.
If you want to use a PS2 remote, you’ll certainly need to know how to program.
In order to make a robot walk, you need to know the positions of each of the joints, and therefore you need to study inverse kinematics.
The easiest hexapod you can create would be two servos per leg, since the SSC-32 has a built-in hexapod sequencer.
Unless you consider a kit, creating a custom walking robot is not the easiest robot to start with.
The SSC-32U has a slot for an XBee module (or Bluetooth Bee etc), so you can send commands wirelessly from a PC or other device.
The SSC-32 however has no “onboard intelligence” and as such it requires an external device to provide the movement commands.
I built my 3DOF hexapod spiderbot using 9g servos. Its a small bot . . . I would like to learn the IK equatiin but dont know any body tgat knows trig. Was actually hoping the software came with a IK calculator or something like NUKE.
Ok knowing that i want to use a game controller handle to control my bot what electronics would you reccomend? Prefer low budget.
All right so I will need all three products? How big is the botduino? Is it the same size as the ssc-32. I only have so much space to mount everything on the top chassis plate.
There’s no guarantee that your robot will mechanically be able to support itself though… so we first suggest testing with the body supported but legs free.
You likely need to calibrate each servo. The walking algorithm requires that the feet contact at a specific location, otherwise it will look quite awkward.
If it’s a matter of the servos themselves, it’s a lot harder to fix.
