Hardware

Power

Onboard battery packs along with ability to charge via other means. Should it be able to operate as a power bank? Target usb-c PD 60 or 100W? What does that require? Target run time with all systems online?

Batteries

Would like to have hot swappable battery packs as part of the design. Maybe on either side on the top or bottom of the bot. Think about positioning and strain on the motors. Onboard charger system would be nice and a BMS? BMS as part of battery pack or onboard with just cell leads exposed through a connector? Dump packs or smart ones? What should the amp hour target be? Would be nice to have a limited current mode that only has required nodes active on the turing pi 2. Built in or external BMS? likely internal, but try for weight savings.

Turing Pi2

Used for running ROS and any machine learning models on CM4 or Jetson boards along with sensory data capture and logging.

One slot may be given the role of main to manage local network routing and basic system functions with other nodes coming online for additional compute or resource access.

Connectivity

• CAN-FD, interface device, via USB or mini PCI-e (IPEH-004046)

Connectivity

Potentially has a wireless modem in one of the mini PCI-e slots, one of the units can also be used to connect and share their wireless connection with the other machines on the network. Would have to research that

Motor control

Undetermined currently, lots of open source motor controllers to run and power motors.

Ideas

use a ribbon spring or some sort of tension-able spring to offload the load on actuation motors.

Tool space and cargo

That is the whole point of a backpack right? It should hold things? Modular bottom space, Could be used to make a Uniwheel motor and controller for a fun rideable backpack design. Once done, You could put it on your back for storage.

Attachment points

Rail system

If the rail system motors are removable, It is possible we can use the rails as an additional attachment point for power and drive motors to make the backpack into a mobile robotic platform as needed.

Near the top or bottom of the rail may be a hookup location with CAN bus and power. Additional data connections may also be available. When sliding out the rail motors, you may be able to cap off/terminate these connections or attach the drive system.

Head

At the "top" of the backpack there may be a grip handle along with attachment points for cameras and other sensors. This head would be able to rotate to view over the shoulder as well as to look backwards or around the backpack wearer.
