Firs competition behind me – second place in free-ride

Written on April 24, 2012 at 13:15, by

Hello,

   I’ve had few very hard weeks… All the little thing I left for later backfired at me, and only by some miracle I was able to deliver at least mechanically complete robot to the Istrobot competition.

   The main thing I learned here is – the robot is ******* heavy and I need to add something that makes him at least theoretically transferable by at least 2 adults… maybe some extra handles will do.

    In the end, it was a great day, I talked to lot of great people ( I wish I could have talked to more of them dough… ) and the robot looked great - definitely a highlight of my year.

Now, you should get pretty good though on what I’m planning

Hello,

   after busy Saturday, I have some results I want to share. On the image is Spirit Junior in the current state. Almost all parts are on place – only arm is not there because some of the parts for it were faulty ( because of faulty blueprints of course, Tatrarez did great job as always ).

Hello World, my name is Junior, Spirit Junior

Brace Yourself More Parts Are Comming

Written on March 9, 2012 at 16:33, by

Hello,

it looks like yet another weekend will have full and juicy robot flavor – the parts for arm and new version of tower are here. And again, it’s bigger and heavier than expected… I also found out, that if this robot stuff wont work out that well, I can use some parts to turn myself into wolverine…

Another step right direction

Hello,

   the post I made on Saturday, was actually my last project-related thing I did that weekend – I got sick, probably due to overworking … So I took day off and the result is I have the other arm finished, and I feel sick again…

     It is a lot heavier than I expected it to be, to my luck motors have a lot of spare power too…

Week no. 8 – The busiest of all weeks.

Written on February 21, 2012 at 15:35, by

Hello,

   last week and a half I’m constantly doing something robot related. Even during sleeping I have weird dream about me being on some competition and nothing is working… I hope, this phase is coming to a successful end…

   So what have I been doing?

  • painting stuff
  • completing wheel setups ( tires, wheel hubs… )
  • testing em
  • fixing mistakes in blueprints
  • making new blueprints of those few parts that were not done yet
  • beginning to know the Efika ( my new linux brain for spirit )

   Here are some images of Efika, efika running and blueprints of parts for my arm with gripper.

Hopefully all parts needed to build the arm with gripper

Week 6. roundup – constructing, constructing and again – constructing

Written on February 12, 2012 at 20:39, by

Hello,

   this week was fully denoted to construction of robot. Throughout the week I was putting together wheels, but as the method was as wrong as it gets – the water-beamed parts were manufactured from 2.94mm thick aluminium instead of 2mm… Firstly I tried to brush it to 2mm, but as I wrote earlier, it failed. The breakthrough came in on Saturday ( day devoted to methodology ) – I begin the widening of the original 2mm cut-out to 3mm. That worked perfect and from 6pm Saturday to now I made another 3. Perfect!

Original cut-out was 2mm wide, parts are 2.94mm wide...

 

Result of hard work weekend

Week 6. – the construction

Written on February 6, 2012 at 15:58, by

Hello,

   as I have all the parts I need, I started the construction of rocker-bogie. I wish there was a little warmer outside, it would speed up the whole process. As first I tried to put together the wheel setup, that in this case contains servo power gearbox for steering, DC motor and 1:26 planetary gearbox for propulsion. Six of these should give an unprecedented ( for me  :) ) maneuverability for my Spirit Junior. The first prototype suggest it could work! What I’m especially proud of, is that the gearbox is fully covered by the wheel as planned, the DC motor sticks out less than 50mm.

Week 5. Update 2

Written on February 3, 2012 at 09:22, by

Hello

   I have the custom water beamed parts! Some of them are still rough on the edges, but it is far better that the laser cutter parts for the first version of project. As I need to paint them first in order to start building, I will have some delay as it is -16 degrees ( Celsius ) outside.

   Today, around lunch, I should have a package from UPS containing the last part for the rocker bogie – the 1/2” precision steel shaft.

Week 5. update

Written on February 1, 2012 at 13:07, by

Good news everyone!

   I keep receiving postal packages everyday – last week it was aluminium profiles, camera, one miter gear; this week it were 2 other miter gears, 3 dual motor drivers, 6 planetary gearboxes ( 1:26 ratio ).

   As the water-beam-cutter parts should be finished just about now, this might not be last post for today…
