**hard control **
Nice job ! There is no way to control the servo and a speaker ?

i have built the robot but the proggraming isn’t working
RC radio control interface?
I have several RC multi channel radios and receivers and am wondering how to interface an RC receiver to be able to remotely control the robot? I am looking for ‘go forward’, ‘go reverse’, ‘go left’, ‘go right’ commands at a slow speed, for say 2 seconds. The output of the receiver can go to a servo or a switch (on-off). Without going into complexities of PWM , is it possible to just detect a pulse on one of the say 4 input pins, to then enable the FWD, REV, RGHT, LFT commands?
Motors not working
I’m very close to getting my first working version, but have got stuck right at the end. Everything, including the sensors and servo, have been working fine, but the motors are not. If I enter
high 4
low 5
Then one of the wheels turns as expected. But if I do
low 4
high 5
The wheel turns in the other direction, but only really slowly. And the Motor Driver IC becomes very hot. If I try the same with 6 and 7, the other wheel doesn’t turn at all, but the Motor Driver IC still gets very hot. If anyone can tell me from this description what exactly is going wrong with my robot, I’d be very grateful. Thanks!
Delivery=$100
Hey I am very interested in robotics and I would love to try this project but I live in England so the delivery is $100 is there any English sites you reccomend?
YAY my first post and I can help someone

Q’s
If you don’t mind I have a few questions about the stuff on the website:
Is the PICAXE-28X1 IC microprosessor in the PICAXE Starter Kit? and
What did you do with the extras, can you post a picture?
Thank you
Yes the microprocessor is
Yes the microprocessor is included in the starter kit. The download cable is not so you need to make sure to order that separately.
I havent even built my bot yet, I am still experimenting! I am still very much learning about all this, but I intend to use the LEDs to make flashing lights etc, the piezo element to make sound/beeps/play tunes, the LDR to make the bot do thinigs depending on how light/dark it is, and the foamboard to build a chassis for the bot
(PS, I have since discovered that you need to get a 10k resistor to use with the LDR, which i just picked up from Maplins for 29p)
What to do?
I am wondering what I can do with this robot. Are there any other thing that I could program to do? What other sensors can I use? Thanks
I think you should be able
I think you should be able to find a lot of inspiration by looking at

You can build anything after doing this project
Thanks
Thank you!

**Great project **
Hi.
Just finished the starter robot. It works great. The hardest part was finding the words to register and post comments (150talented).
The only problem I had was not realizing the wires from the Sharp had to be cut and swapped. Once that was completed, she worked fine.
I’m not a coder, but I’m looking forward to playing around with it and adding the lights.
Great site!

Thank you for showing this. My board came with a chip in place and these 2. I had to the remove the one that was preplace in there and match the above placement and viola, it worked. Thanks.
It isn’t supposed to be easy
It isn’t supposed to be easy to register, that way spam bots can’t get in, Please delete the answer from your post if you feel so inclined.
what can i add to this
what can i add to this robot? , because the only thing that he do is walking !!
