Let's Make Robots Robots
1

For my 2nd project i will be making a 6 legged robot that can move in all directions (fingers crossed) like Steg ill be making it from the ground up and prob get a few grey hairs!

<< Goals >>

  • Build a walker using tripod gate motion
  • Able to move in all directions Control by remote > r/c
  • Gain more hands on xp for bigger complex projects
  • Able for wet/dry and rough/smooth terrain

 

Leg layout and frame design

having the gears to tight seems to cause too much friction and too loose adds the danger of gear slips. This way worked just nicely for me.

It also allowed me to work out which directions the gears would move so that i could make sure all legs move in the right way and not lock up, a chain and sprocket method would have been ideal here but i went with the cheeper choice.

 

 

 

 Glued in with super glue and then reinforced  with thick over night drying glue, weights  added down to give a better bond. 

 These parts will make up the 2 main side  walls  of robots frame allowing the gear  chain to be  connected to the gearboxes.

 

 

 

 

 

 

 

Main robot frame

Made from bolster wood and match sticks to keep the weight down as much as possible

 

 

Gearboxes

My 2 homemade 3v gearboxes, primed and greased!

 

 

Leg cranks

Decided to again make the cranks myself, it worked out better as the retainers were able to be more secure and fit in snug. Took my time on these as they need to be very secure, used matchsticks and a combo or fast and slow dry glow with clamps.

2 made for each leg, so 12 made in total, retainers glued in placed for a solid rotation.

walks/runs in all directions, r/c control

  • Control method: Radio controlled
  • Power source: 4 AA batteries
  • Target environment: indoor and outdoor

I am so impressed I wish you had more comments!!!

Dear: Gizagon

Absolutley fantastic work my friend!!! I love the mechanical you did!!! How did you design this robot? Maybe it could help me in the future. I just wish I was as skilled as you are at mechanical. Thanks!!!

Thank u for ur kind words =) designed the base build on about 10pages of A4 with many different variations most of which went into sci-fi territory :smiley: what i learnt from building steg helped me out a lot here, so the design was adapted from my previous build. Your as good as u feel Noah, keep it fun and the results are auto. Measuring ruler, hacksaw, sandpaper and a tone of glue can get u a long way ^^

That’s the true DIY

That’s the true DIY spirit!

Thank you very much for dedicating your time posting this nice project, with a good write up and pictures.

nice!

Indeed very cool that you made everything yourself and basically out of nothing. I also saw your youtube video of all the gears running. Can’t wait to see it walking.

Hello Dannyv

Thanks, lot of sticky fingers with all the glue! had to wait on a new order for parts so things came to a stop, got them now though. Back to work =D
