I am creating an autonomous platform that will move about a stage. The platform is 8 feet by 8 feet.
The main problems that come into play with this are:People walking around the stageWireless: microphones, phones, equipment, and misc.Lights in many different colors that may output Infrared lighIndorsLoud speakers(many different types)
My initial thought is that using IR sensors and Ultrasonic sensors would no work in this case because of the various types of interference. MY thought was to triangulate the position, but I have no idea where to start to purchase (preferred) or create the towers and the receiver.
Hi,I don't see how you'll get reliable odometry data from a holonomic drive, as you cannot tap all the rollers on each wheel?A spring loaded dummy caster wheel with encoders on both the wheel and the caster itself (measuring angular displacement from eg. straight ahead) OTOH is doable.There's just the problem of accumulated errors with odometry (whether a wheel or optical flow is used), unless it can be "homed" every now and then.Why would tape be a problem?Clear tape 4..6mm wide with a thin wire in the middle is nearly invisible (and nobody will trip over it. The aluminum tape used for window glass (for alarm purposes) could be used as well.
could you please describe how to use the tape method more, or a link to a site about it.
The cart will follow a predetermined route to various points.
It will have to watch out for people and/or objects that may be in it's path.
