We have decided to build some sumo robot at the hackspace, so i decided to take up this challenge here are some pictures from the build.
|
|
|
|
|
|
** Problems
|
|
Attempting to cut out a large circle with the tools i had available proved to be tricky, tried using a router attached to some ply initally but this struggled to cut well.
|
|
|
|
In the end i used a jigsaw this worked quite well but the curve of the circle would move the blade away from its centre guild and caused me to take some chunks out that i had not in tended.
|
|
|
|
** The build

** The final ring
|
|
|
|
I am reasonably pleased with the outcome it certainly could have been better, if i had cut the initial circle out more accurately also the rim could have done with being thicker to support the weight,
|
|
this would likely have been harder to bend with the tools I had available.

** Lets build some robots
|
|
So now we have a ring lets build some robots, we can use them to test ideas for pi wars next year as well :)
|
|
|
|
I propose controlled for now, and small in size perhaps with these dimensions based on online dimensions.
|
|
|
|
500 millimetres high
|
|
200 millimetres width
|
|
200 millimetres depth
|
|
3000g weight limit
|
