YOUR FIRST ROBOT - PHOTO SEQUENCE



The first prototype you will make at the beginning of your robotics career is this amazingly powerful but cost effective three wheel P1X8 robot that is easily programmed in uncomplicated BASIC.

Once you've made this robot and found out just how clever you really are then more challenging projects will follow.

More powerful platforms and more powerful languages like JAVA and the C family of languages will not seem so mysterious or challenging once you've mastered the basics with BASIC!









This is what P1X8 that you are about to build looks like when complete...



This is where you start...



Check the parts fit...



This is a 15 hole LEGO beam...



Not part of the LEGO system are the M3 cap head mini nuts and bolts to hold everything together...



Note the use of black LEGO pegs to holdthe strips in place until we screw it together...



The grey spreader will ultimately hold the battery pack ...



These parts will hold the rear ball coaster wheel assembly...



Fortunately the M3 screws fit perfectly through the middle of the LEGO peg...



Allan key and pliers to tighten - but do not overtighten and crush the plastic parts...



This assembly will hold the ball coaster wheel...



Correct positioning of the second battery holder LEGO beam...



These are the parts you need next - note the extra LEGO beams the battery pack rests against...



These parts will hold the servo motors in place...



Clip them together...



Note the position of the LEGO pegs...



Make sure these are placed in the right spot so the servos fit...



Put all four M3 nuts and bolts in place to hold the servos before tightening ...



... because the holes do not line up perfectly ...



Allan key and small pliers to tighten so they do not rattle lose...



Here we have LEGO axle and spacers for the silver necklace coaster ball...



These are the parts you need to make the coaster wheel support...



Note the blue splined type LEGO peg and black round LEGO pegs...



Clip the parts together...



Coaster ball in place...



Fit to robot...



Screw the lid wheels to the servo motors. On this website you will also find a photo sequence of how to modify hobby servos to use with this robot and how to attach the servo horns to the wheel lids...



Do not overtighten the screws that hold the wheels to the servos - you can strip the shaft with excessive force ...



We use six rechargeable batteries to power P1X8 in an environmentally friendly way. Do not leave batteries charging when you are not around because like most electrics things can go wrong...



Note the use of elastic bands to hold the batteries in place to keep weight and costs down...



Pretty neat when complete - now look at our programming pages to get started through that robot maze...
