Autonomous Rotacaster Omni-Bot

This Autonomous Quad Drive Omni-Bot fitted is with Rotacasters Omni-wheels and uses 4x Ultrasonic Sensors to aid in navigation. It’s based on my previous Quad-Drive Rotacaster Omni-Bot with the addition of the Ultrasonic Sensors. The main challenge is to use all 4 Ultrasonic Sensors without them interfering with each other, resulting in non-valid measurement readings for distance values to objects.

As I have a set of four Rotacaster Omni-wheels to test drive, I decided to build a 4-wheel Omni-Bot for a change from the normal 3-wheeled versions. Build a solid & compact 4 wheel platform wasn’t as easy as I first envisaged. But after 3 attempts I hit upon something that worked. The Lego purists may no approve of the way I had load a few joints to get it too work.

Peter McKinnon from Rotacaster pointed out from looking at my last update the  I’ve managed not to take into account that for proper Rotacaster Omni-wheels action to work on myOmni-directional robot, the wheels have to always remain parallel to the ground. When the legs were raised & lowered independently, or together  the wheels where never parallel to the floor. My initial response to Peter was thank you for bringing it to my attention & it will be an easy fix.

This is as far as I’ve managed to get without the proper Rotacaster Omni-wheels on my main Omni-directional robot. The legs can be raised & lowered independently, to lift the body 150+mm above the floor. The 3x Ultrasonic Sensors appear to be working together and measures the distance to objects o.k.I’m now working on programming the behaviours and using the Playstation 2 Controller.
