Review: Hexbug Spider Robotics Kit

A kit to build a hexapod that with various automated behaviours and can be remote controlled

Once again I was lucky enough to be selected on LMR to review the Hexbug spider Robotics kit. I was over the moon; I have always wanted to build a hexapod but have always felt that such a project would be a bit too big, given my little understanding of controlling mamy servos, inverse kintematics etc.

This kit is a fantastic step for beginners to get a taste of hexapod building, and features some great design to only require two servos/motors to move!

 

Unboxing

The kit arrived well packed from RobotShop. Inside the box there are sooooo so many parts, but they are all organised and grouped into separate bags to make co-ordinating the build easy!

 

Assembly

Putting together these hundreds of pieces is made easy thanks to a great instruction manual. Each step is clearly illustrated and even features 1:1 scaled pictures to aid you in ensuring the right parts are used at the right time. The kit all snaps together much like Lego Technics or K'Nex, so kids will have a great time putting it together. Parents can also rest easy knowing they dont have to arm their kids with weaponry such as screwdrivers :-)

Assembly time - it didnt take long at all. Adults can fly through assembly or it could make a nice afternoon project to put together with the kids:

 

 

Unfortunately in the final few steps i found I was missing one single, solitary part to connect one of the limbs to the body - sad times!

Luckily, after contacting the RobotShop support team, a replacement part was ordered at no extra cost.

As soon as I receive the missing link I will be shooting some live action videos to capture my first attempts at piloting this beast, as well as exploring what automated behavior the robot is capable of.

Until then the Spider Robot has been employed to guard the booze on the top of our fridge:

 

 

16/11/2015 - IT IS HERE!!!!!

Today, after a long, tedious day at work, I cam home to discover a mystery package. Measuring a good 6"x4"x3" in stature, I was not expecting anything that size?

I cracked it open, lifted out the packing paper to reveal a lone delivery note; was this an empty box? A cruel, sick joke?!

No - trapped betwixt the sheets of packing paper, it sat there, in all its glory...

Soon you shall walk, my pretty... SOON YOU SHALL WALK!!!! Muhahahahahaha!!

 

With the elusive link no longer missing it was time to load the beast up with batteries...

The control unit takes 3 x AA batteries. While this is a convenient battery size I think that this thing will eat those three little AAs as a snack, given the onboard motors and sensors. I would have liked to see a rechargeable solution here, such as a Lipo. I may look at getting slme rechargeable AAs, but onboard charging would have been ideal!

Walking - Coming Soon

Just a quick little update until I get a chance to write up some more of my review. The Hexbug is a hit with my son! He has asked to see 'Mr Spider' every day since I was able to get the assembly finished, which is great - definitely opens the door to introduce some more robots for him to play with :-)

I initially harboured concerns tat the motors may struggle to turn the geared assembly due to how stiff it was to move by hand, however it moves like a dream; such a smooth walking motion!

I was always under the impression that good hexapods needed articulated, 2DOF or 3DOF legs to get a good walking motion.... I have been proved wrong.

 

Automated Behaviours

After a bit of time away from my projects due to an intensely busy period at work and gigging I am picking up where I left off, and will be updating my finding on automated behaviours very soon. I have often been puzzled at the random actions my Spider untertakes in autonomous mode... Are my dip switches not doing what is expected of them, or has my Spider developed AI and become self aware?

More to follow soon!

Overall - Coming Soon

 

22/03/2016 UPDATE

Apologies for the late followup, but more will be coming of this review very soon.

the toy has been a resounding success with my young boy; he loves playing with it, triggering its sensors and following it as it wanders around our living room.

I do have a great deal to report regarding it's performance of the preset behaviours. Hexbug may well have inadvertently created true AI!!

Great start Craig. Looking forward to seeing more of this Spider. I did not think it was this large.

You're not the only one - it is huge! The box it was delivered in was absolutey enormous; I thought I was looking at at least a waist-high bot at first ha ha!

It's killing me being one part away from having it up and running ha ha. Looking forward to getting it up and running. The mechanics of it are beautifully simple and I can't wait to see how it handles.

I am also looking forward to seeing what it can be coded to do with the dipswitch-based onboard control box. The instruction manual doesn't mention what it can do so looking forward to finding out the hard way :)

Can't wait to see more!

You guys have already said... but it's really big! I'm impressed with the size!

Cool thing to have walking at home!

It is certainly value for money on sheer size and mass alone :)

I cant wait to see it in action either; I cant wait to see how the two motors handle the movemenr. My son even says good morning to mr. Spider when he sees him on top of our fridge - seeing him walk is going to blow his mind ha ha!

Just had an email to confirm the missing link has been despatched and its on it's way - good times!

Post doubled...

Hi Craig

Glad to see your bot complete and walking on it's own feets ☺

Great job so far :)

I'm eager to see how programming phase goes and if my findings about DIP switch combinations are the same in your case.

-=Seba=-

 

Trust me, you're not as glad as I am ha ha!

I had a play with it for a few minutes last night, just on RC mode, and I love it! I never expected such a fluid movement from it to be honest.I quickly tried autonomous mode and ti appears to be in an object avoidance mode  as standard.

 

I will definitely try to log my findings in a similar fashion to yours for ease of comparison.

 

I put on the following link the files I used to create the review posts - Google drive folder

I create and edit .svg files with Inkscape and after that export the vectorial drawings in PNG format.

Hope it helps

Thanks mate!
