Hi all.

Anybody knows how can I correct these?

Thanks for any help.

Hi, anybody knows the disadvantage of the 3d structure produce by octomap?

I know the advantages are: 1. Probabilistic representation 2. Memory-efficient 3. Flexible, multi-resolution

Any disadvantages?

Thanks!

Roger that. Thanks for the info.

I posted on two website just in case one forum is inactive. I have closed the post in Robotics Stack Exchange already. T

Thank you very much. Yes, I am using gazebo as part of the simulation but I think I might have missed this one out.

Dear all,

I am not experienced in doing robotics. I have been trying to find the max linear acceleration of Husky A200 in order to set real constraint for simulation purposes.

What I did was to find out the drive power of the Husky A200 (https://www.google.com/url?sa=t&rct=j...).

Drive Power = 400 W continuous (4 wheels), thus Drive Power = 100 W continuous (1 wheel).

Using

Acceleration = Power/(Mass x Velocity), where max velocity = 1 m/s (also in the link above) and Mass = 57.69 kg

I got

Max Acceleration = 1.733 m/s^2

Is the calculation correct? If yes, what does it mean when Max Acceleration > Max Velocity in magnitude? Does it just mean that the velocity will just be capped at 1 m/s even if the velocity can be increased by 1.733 m/s in a second?

Thanks for viewing.

What is the max linear acceleration of Husky A200? Dear all, I am not experienced in doing robotics. I have been trying

Good day to all.

I have encounter a few errors while building hector_navigation package.

I'm using catkin workspace. During catkin_make, I encountered these errors:

Hi all. I'm using a drone and to be display in RVIZ, I need to have a Z axis to see the height of the drone to ground.

However, my RVIZ got only the X and Y axis. Only views in 2D. My robot's frame does not go up or down, only can navigate around the 2D plane. Anyway I can set?

Thanks!

Hi guys. I got problem with the network when im using urg_node for Hokuyo Laser Scan.

After running roscore, I start up urg_node with:

rosrun urg_node urg_node _ip_address:="192.168.0.10"

However im getting an error that states:

[ERROR] [1434516842.963885543]: Error connecting to Hokuyo: Could not open network Hokuyo:
192.168.0.10:10940
could not open ethernet port.

I looked this up at Google and many of them said to configure the IP address to 192.168.0.15.

So I edit /etc/network/interfaces with:

sudo nano /etc/network/interfaces

and replace the text with:

auto eth0:0
iface eth0:0 inet static
address 192.168.0.15
netmask 255.255.255.0

I tested the urg_node already and it's running.

However, another problem came up. I could not connect to internet. My wifi speed stucked at 1mb/s (using ubuntu now).

I came out with another solution by editing the interfaces file to:

auto eth0
iface eth0 inet dhcp

auto eth0:0
iface eth0:0 inet static
address 192.168.0.15
netmask 255.255.255.0

In this case, I can change to use eth0 (able to connect to WIFI but cannot run urg_node) and eth0:0 (cannot connect to WIFI but able to run urg_node) by using this two command:

sudo ifup eth0:0 (Set eth0:0)

sudo ifdown eth0:0 (Return back to eth0)

I was wondering whether there is a way I can combine these two function together, that is able to connect to WIFI and run urg_node.

Thanks for any help!

Can someone help me? Thanks!

Thats great. Wish you all the best!

If you check and everything is identical to mine, try: sudo ifconfig eth0:0 192.168.0.15 up

this will disable your internet connection. Try connecting to hokuyo now.

To enable internet: sudo ifconfig eth0:0 192.168.0.15 down

Can you type sudo nano /etc/network/interfaces and verify the interface? Are you still able to connect to WiFi?
