Impact of Bumps

[BrianCloutier]

CRUSH whipped up a prototype of a robot and bump today, and played around with the two to get a feel for how the robot could handle bumps. Here's a few pictures of our prototypes. We also took a video, after it's done uploading I'll post a link to it.

Here's the video I promised of a robot tackling the bump, http://blog.crush1011.org/post/333591755/it-works-almost-stay-tuned-for-a-video-summing (We used a prototype because none of our existing robots had enough ground clearance to even attempt the bump.)

And another summing up our entire meeting yesterday, http://blog.crush1011.org/post/333597612/keep-up-the-good-work-team-crush-were-trying-to

Enjoy!

Guys,

Nice work - Be careful to pay attention to how a robot will behave when it is propelled by wheel torques instead of pulled by a rope.

The forces the wheels create have different locations and directions than the rope force, and as the robot tilts they vary differently than the rope force varys.

Especially with a wide robot. A more narrow robot would be more stable going over the bump.

not necessarily, since the angle of the bump is 45 degrees, a narrow robot may make a turn while its front falls forward after going up the bump. (im not sure if you can understand what i wrote)
