 Finally, they're getting rid of the spotlights. I'm sick of seeing ridiculous inside jokes up there. - Karthik [more] |

Re: pic: All folded up
The 64:1 banebot gearmotors ( one on each ramp) driving lead screws drive each ramp over center where they fall to the carpet. The big ramps fall is cushioned by a "pool noodle" and the small ramp by dense foam. Works great but you don't want to be in the way when they deploy.

Re: pic: All folded up
Are you going to add some filler weight to bring it up somewhere near the limit for whatever class you're in? (What class is that, by the way?)

Re: pic: All folded up
Yes, we're going to be in the 6 ft 100LB category. We'll make sure it weighs very close to the max weight. With bumpers and the battery our weight will be 128 LB. We're going to play defense during the first part of the match. Can you imagine trying to see around a 72 inch by 38 inch piece of diamond plate between you and the rack? If we don't move at all from our starting position in the home zone and just deploy our ramps at the start of the match we've blocked the other alliance from getting to a lot of their tubes. With about 20 square feet of 12 inch high parking space we have plenty of easily accessible space for two robots.

Re: pic: All folded up
What kind of hinges are you guys using to attach the diamond plate ramp? I see two there, they seem rather small too.

Re: pic: All folded up
Hi Ryan, Both ramps are attached with two commercial grade 1 1/2 x 3 inch steel hinges ( about the only steel on the whole bot). The heaviest ramp is only 20 LB. To test the hinges and ramps we've had 200 plus pound boys stand on them with no problems.

Re: pic: All folded up
Very nice.
 What made you choose diamond plate? (Just curious about your thought process as you went about making the ramps.)

Re: pic: All folded up
diamond plates are great.
thats what we are using also. 1/16" diamond plates are relatively light since they are stamped and provide some traction for robots to climb. However, it costs a lot!
