    08M Robot with Full Motor Control and a IR Distance Sensor

    I ran across this little bot while searching Picaxe projects. I found it quite interesting how he uses the 08M to control a SN754410 motor driver chip and a Sharp IR sensor. Not sure if anyone has seen this bot before but I liked how it worked. The OP includes a schematic, code and video...

    Picaxe Class

    Well done Mr. Erco... that class would have been just too much fun! Especially combining two of my more favorite pastimes, Picaxe and cold ones! Wish I could have been there. I will keep an eye out for your project write-up. Cheers! -Gary

    Hey Mr Hemi, Thanks for the good words! Glad you liked my bot. As for the polycarb part, I bought this for a dollar a while back. Supposed to fit a SRF004 but never did. I had to Dremel the holes to get them 1.5mm closer. It finally found a home on this bot. We bend pieces of polycarb at...

    Well, it is not the best Figure8. The path is never the same as the front tires can skid a bit when it hits a slick spot. Path is timed. Hey Erco... Hope this will qualify for the Figure 8 Challenge!

    Hey Erco! Good to hear from you! I accept the figure 8 challenge and will try to get you a video soon. I did get my program working with this bot, not perfect, but a decent start. -Gary

    Thanks Ibenson! Linkage is just a bent wire going from the outermost hole in the plastic servo arm to a similar brass arm on the steering post. I have it capable of turning 30 degrees each way from straight ahead.

    Latest Robot

    Just finished building this bot yesterday. It looks a lot like one I made 2-yars ago but with some improvements. New robot is more compact, has ultrasonic sensor instead of a Sharp IR. Motor is from an old floppy drive and the gearbox is aluminum bar stock with gears and tires from slotcars...

    Twinny M2 Robots

    Hey Erco! Now there is an awesome pair of bots! Well done! I am going to have to try making another with a chip larger than my usual 08M2.

    Code Error

    A few years ago I made this solenoid engine. The operation uses a Hall effect sensor to fire a transistor (TIP 105) to switch on the solenoid current. It stays on for about 30 degrees of flywheel rotation and shuts off the transistor. Max speed @ 9vdc is about 180-200 rpm. Here is a link to the...

    Less Is More 08M2 Robot

    Erco... I took your advice and added the IR receiver for an extra remote control. All my IO is now used. The code has been re-written for the IR. All that is needed is the universal tv remote. See if I can find one this weekend. Here is a new photo of the robot.

    Less Is More 08M2 Robot

    Hello All, I built a robot using the 08M2 chip. I have a write up on it on this website: [URL=""/URL] It ran ok with the original code but I wanted to update it. Here is the updated code: '**************************** 'Robot#2_R1.bas 'Picaxe 08M2...

    Need a Point in Right Direction

    Greetings All, I have built my BeerBot and have it in the Blogs. The final bit of wiring I need has not shown up in many searches. I use 2-protoytpe boards. The AXE118 with a 20M2 and the 08 Protoboard with the 08M chip. 08 runs the Tenda Speech board and the Adafruit Audio amp great. 08...

    Here are a couple more photos of my Robot. Am still looking for the way to wire up my 20M2 and 08M protoboards so I can send a signal to play a certain phrase based on the program.

    I started working on this robot about 3 months ago. It uses a RevEd Axe118 20M2 Project Board as the main controller. Another board, L293D handles the drive motor. Steering is done with a standard size servo and a smaller SG90 size rotates the Sharp IR Sensor. I made the sensor plug-in board...

    08M2 for my Project... maybe

    Greetings, I have finished the build of my project and now for the controller. Reading the manual and searching the Forum it looks like the 08M2 will work with 6 I/O available. Here is the list of what I need to control with what I think will work : 1. Single Motor control thru an L293D...
