This repository is CPP port built on the commendable work of https://github.com/Bin4ry and team in free-dog-sdk. The code has a number of improvements, but it only has low level control.
Use the standard process of cloning this repository, making the build folder, running cmake, running make, and installing.
Execute the following code on the robot's Raspberry Pi：
sudo vi /etc/sysctl.conf
Remove the comment in front of net.ipv4.ip_forward=1
sudo sysctl -p
sudo iptables -F
sudo iptables -t nat -F
sudo iptables -t nat -A POSTROUTING -o wlan1 -j MASQUERADE
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i wlan1 -o eth0 -j ACCEPT
sudo iptables -A FORWARD -i eth0 -o wlan1 -j ACCEPT
Do the following on the PC running this code：
sudo route add default gw 192.168.12.1
You must establish a unitreeConnection object to get data. This takes in a tuple of the following:
- listenPort -- What port you should reserve for listening to connections. Arbitrary.
- addr -- The address of the robot. This should be 192.168.123.10 if you are connected via Ethernet.
- sendPort -- The port to send to. This should be 8007.
- localIP -- The IP of the computer running the code. It is recommended that this is set as 192.168.123.14.
See example/example_position_lowlevel.cpp for an example.
Elevate the dog using a box so its feet are not touching the ground and the front right leg is free to move.
Then run
./free_dog_sdk_cpp_example_position_lowlevel
The dog's front right leg should do a sin motion.
Absolutely NO warranty. This is not intentionally designed to but may inadvertently destroy your robot.
