TRM Navigation Robot

Lipo’s are the way to go

Lipo’s are the way to go overall. But I switched because of the cost of the lipo charger, and the D battery holders add a rigid reinforcement to the chassis. Plus the servos don’t draw that much current, so the D cells provide a long enough run time for this application. But I might switch back later on, if run time becomes an issue.

A couple of my local robotics group members want to try a variation of magellan, where the robots run the bases of a baseball diamond. Personally I want to build a larger SRS Magellan robot. So this is my test robot to work the bugs out before actually building a large scale version from a wheelchair base. So this robot is destined for the baseball diamond game, which should be a good method for testing navigation strategies, for when I build the larger robot.

Here’s a video showing my wheelchair base navigation robot http://www.youtube.com/watch?v=rgPSAVHrFHI

The double servo steering is great, I might try something like this out, not to the same extent, but I love the smooth turning.

what kind of motor controllers are you using?

This robot uses continuous rotation servos, so all the drive/control electronics are built in.

RE:

None, servo’s have a PPM circuit inside so all that needs to be done is mod them for continuous rotation. The 6 drive servos have this done. The steering ones don’t need continuous rotation.

PPM stands for:

P - pulse

P - position

M - modulation

This reminds me of a type of vehicle used for moving and unloading extremely heavy loads.

All wheels independent, ran using hydraulics. They can be connected in series or parallel for extra big/wide loads.

Good job.

Wow
This bot is simply inspiring. It has such grace and control of where it is going it looks to be the perfect platform for a navibot. Well done sir!

How it will climb

hai cool… a big idea (with 12 servos)… but what it will do while reaching the stairs…

Thanks, I really need to update these old posts. I have video of it navigating a city block that I never uploaded (big file size as the robot is slow).
