This another 3D printed single motor toy robot. This is a pin walker. It has pins in the legs to drive it. It can walk forward or spin in place. It's based on the same mechanisms as this one:

The main difference...
I've built another single motor robot toy that can be controlled by a Picaxe 08M2 and an IR remote. It uses the same board as my previous design. It will move forward or spin on its axis for steering. When the motor is run in the forward direction both wheels rotate in the same direction for...
Thank you for all the kind words Erco. I'm blushing.
I have not seen this Furby teardown video before but I bought one many years ago just so I could take it apart. I've been interested and inspired for decades by this sort of design. The Tomy toys like the Armatron , thier toy pinball machines...
It's been a while since I've done a Picaxe project. This one is small robot toy driven by a single N20 gear motor. It is controlled by a universal remote. When the motor is run in the forward direction it drives a gear train that turns the selected wheels. When the motor is driven in the reverse...
That schematic is very impressive. How does follow me mode work. I built a replacement remote transmitter for the Robie Jr. It had a follow me mode but that remote transmitter used ultrasonic sound. The robot had ultrasonic sensors in it's shoulders. I assumed it used the time difference for the...
Hello Bill,
I've never used the microsoft 3d modeler to design anything. I tried Freecad but it was very frustrating. My original printer is a FlogerTech 2020. It has been heavily modified. It looks terrible and sounds worse but it prints great. I just bought an Ender 3 V2 Pro 2 months ago. I...
Hello Bill,
I've been away from the forum for awhile. I check back in every so often to see what kind of trouble erco's getting into:). Glad to see you were able to make a 3d printed version of it. It was a challenge getting it into 256 bytes. Can't believe it's been 10 years since I build...
Do your parts look like this?
I'm just afraid I'll run out before I go.:)
I've added homing to my machine on the X and Y axis. It's a little more elaborate than a simple switch though. The schematic is at the 5:18 mark in the video.

Hello lewisg,
I worked on some code a while back to produce IR control signals for different devices. It runs on a 14M2 using the hardware PWM and DSM for the output to the led. It can output up to 64 on/off pairings with a minimum pulse width of approximately .000266 seconds. The method I used...
Here's an interesting "feature" of the pic PWM module. If you use 255 for the period , it's not possible to get 100% duty cycle. It would require a value of (255 +1) * 4 or 1024 be put into the 10 bits of the duty cycle but 1024 requires 11 bits. Unless the firmware checks for this value...
