Walking Robots #2 : Tobbie is Completed

dubbie

Continuing with my investigation of walking robots I have completed making Tobbie, as illustrated in the video below. I am very impressed with the mechanical engineering and design of this product and I think it is a great robot. I am sure that there is much more that can be done with this than just playing with it's supplied functions.

 

 

The walking mechanism is fascinating. It uses alternating sets of three legs to move forwards or backwards. It uses three legs because it is always stable so while one set of three legs is on the ground Tobbie is stable, so that the other three can be moving forwards or backwards. I'm not entirely sure how it turns yet, maybe some vector type combination of the two sets of legs.

 

It seems perfectly feasible to replace the existing electronics in Tobbie's head with an Arduino Nano or similar. I might even have a go at this myself.

    Daniel,

     

    It does seem as if Tobbie might make a good platform for some interesting experiments in walking mobile robots. I obtained mine from Amazon where one seller was much cheaper than all thee others. Seemed to be a good seller as it came quickly and was complete.  I think it is a good quality design, but it is important to remember than it is still a toy made from plastic and probably quite easy to break. Good fun though so far.

     

    Th box states it being suitable for 8 year olds but they would have to be pretty aware mechanically and very careful in order to construct it properly. I took three days to put it together as I wasn't in a rush and I carefully removed all the burrs from the injection moulded parts. Some steps were difficult to understand, especially towards the end - six legs do kind of get in the way!

     

    If MyTobbie works out I might even buy some more.

    I can imagine it now... A Tobbie swarm!

    Daniel,

     

    At some point I do want to make a swarm of robots. So far I have just been thinking about making very small ones as they would be cheaper and more manageable. However, imagine a whole host of Tobbies wandering about, although they do seem to be restricted to smooth surfaces which could be a problem, a bit like Daleks in Dr Who.

    How is it that after seeing Tobbie Last week, I saw this hellish monstrosity at the weekend!

    Daniel,

     

    That is quite one of the weirdest things I have seen. However, I do like the walking chassis, which is obviously based on the same approach as Tobbie. It looks more substantial though. I wonder where you can get them.

     

    The laser might be a bit over the top. Probably not allowed in this Country.
