h1. Franka documentation and operating the Pandas h2. Franka Documentation * The Panda User Handbook attachment:pandaUserHandbook.pdf (safety rules, setting/starting up, basic use through the web interface) * The Franka Control Interface & ROS packages: https://frankaemika.github.io/ * The dedicated LAAS robots "wiki page":https://wiki.laas.fr/robots/Panda (basic h2. Misc things * The PC must have a Linux kernel with the PREEMT_RT option * To have access to this option, you must belong to the unix group "realtime" h2. Using your own laptop First you will need a real-time kernel to be able to communicate with the pandas (PREEMPT_RT). The procedure is described here: https://frankaemika.github.io/docs/installation_linux.html More informations in french can be found here: https://bidouilledebian.wordpress.com/2018/05/31/compiler-son-noyau/ The second link might actually be better. Note: avoid the use of the fakeroot command if you have errors. You will also need to configure the network (ethernet). - In the ipv4 tab, choose manual configuration. - Adress = 172.17.1.1 - Mask = 255.255.255.0 You can ping the robot's IP to see if you are able to communicate with it. - Panda1 = 172.17.1.2 - Panda2 Panda1 = 172.17.1.3 h2. Start the pandas: https://frankaemika.github.io/docs/getting_started.html 1. before turning on check on the black button and red button. - red button must be unpressed. - black button must be pressed. - turn on the robot cpu. It's on the back. Panda 1 is the lower one. - yellow light will blink until its on. - when it's on, light remains constant. 2. Access the robot server interface: https://172.17.1.2/desk/ for panda_1 and https://172.17.1.3/desk/ for panda_2 - accept the risks - robot information on IP and credentials are in: https://wiki.laas.fr/robots/Panda - when accessing the server, joints are locked (the panda has yellow lights). unlock them. take care it can move a bit. - it changes the color of the light to white - unlocked but not accept command motion. 3. To move the robot, release the black safety button. The light will turn blue - accepting command motion. 4. turning off - push black button - move to a safe position manually (pushing the two buttons in the end-effector and guiding) - lock the joint in Desk interface - shutdown in the interface- wait until it says you can turn off the cpu - press red button h2. Troubleshooting If you have this error: <pre> linux libfranka: UDP receive: Timeout </pre> This means a firewall is blocking some UDP packets (see https://frankaemika.github.io/docs/troubleshooting.html). You can disable the firewall (should be definitive) by using this command: <pre> sudo ufw disable </pre> Check if it is disabled: <pre> sudo ufw status </pre>
