Let's Make Robots!

My second robot

Drives really fast, but poor, as both rear wheels turn the same, and no weight on front

This time I wanted a faster robot. No turning head, just some parts from old toy, mocked up, and getting much too high voltage!

It went completely beserk, but frankly; It was quite a poor robot, haha. (But fun)

I was wondering if you hooked the battery pack staright to the picaxe. I wanna try but Im afraid of frying mine!

Looks like separate supplies for the brains and the motors. Three 1.5V batteries give 4.5V to the V1 on the Picaxe. The 7.2V racing pack is probably connected to V2 on the Picaxe board.

Search for 'Picaxe for Dummies' post for a great walkthrough of the Picaxe-28 Project Board.

The other motor is mounted up front and turns the front wheels from side to side, just like one a regular car

Yes :) Thanks, maneuver!

Problem, however here, the wheels at the back are locked to each other, they cannot turn independently. This makes it quite crap at steering.

On the project "Wall Racers" I use that to make the car slide / skid. On the project "Skiwalker", there is a short explanation in the video. Member in here, Jip has at some point made some walkthrough on how to make the wheels pull diferentiated by using Lego.

Project "Forfrabagfra" uses 2 times differentiated pull.

.. And this robot, on this page, btw; It was crap at steering, it took a whole football arena to make a turn; Back wheels locked, but with much grip and weight. Front wheels almost no weight, and slick tires.. Really a bad project, but one has to learn :)

But i see one motor only

it can: it says "Actuators / output devices: 1 motor drive, one motor steering"  actually there are two motors

Can your robot turn? i was just viewing previous projects and saw that u use 1 motor? so how goes it turn? Maybe i got it wrong but just asking

im so sorry to hear that i guess he was a part donner then.

He was sacrificed. His internals are now in other robots or the bin / Frits
