• potentiell Sensoren (Bänder), welche ermöglichen die Kraft der Ballberührung zu messen und auch den Schusswinkel estimaten
• Mit IMUs, Wegezellen

1. Remove white gunk and try resoldering strain gauges
2. Order new strain gauge foils (see Order project)
3. Test new ADC chip in breadboard prototype

The new foor in #4 will need a new cover

To clarify if we need software changes we want to test the actual backlash of our legs/motors:

• currently
• with serviced/new motors

use aluminium profiles/extrusions to build a gallows (de: galgen) like structure to hold up the robot

please evaluate the rules before doing this

maybe with battery tester already built in

for x-servos in hip pitch and roll

we might use flexible material or o-rings to hold the cable

We should try to print a case for the nuc to reduce the weight

It should be checked whether it is heat resistant enough.

the neckpart broke frequently during robocup 2019,
it needs to be more stable by using a different material or design

the issues with this part may also be resolved by #1 because the head might be shorter

add another IMU in the head, see #19

• Test the vision, ipm, ... when fixating the head pan joint

• Test doubling up the carbon sheets
• Replace the worst gears
  • Measure backlash of servos using 3D-printed jig (see #40)
• Use x-servos in hip pitch and roll (see #38)

Finish the controlling and regulating electronics

This module should have buttons and some LEDs for showing the robot state.

might already be solved by #21

Provide links to hardware-related git repositories in bitbots_hardware Readme

we lost a lot of gears to this this year

We should have a new, more lightweight foot plate with guiding rails for the foot pressure sensors

Our current 3d-printed PC-holder parts are breaking.
Some may be too short?

Try with different materials (TPU or Carbon-reeinforced)

Was ist die Ursache?

• Kabelführung
• RS485 / TTL mix verhindern

currently the solution is quite hacky

Currently, the quality of our torso bumpers is bad and they break.

We want to redo them (perhaps softer, in other materials?) and reevaluate them. Previously, evaluation has been done by letting robots fall and maximizing the time that bumpers compress.

Maybe get inspired by the designs of CIT brains or Rhoban.

This happens, when servos use a lot of power
We could use a boost converter to stabilize voltage to the PC

- [ ] Order and test boost converter (see Order project)

Update August 2023:
Unwanted shutdowns still sometimes occur, but due to another suspected reason:
Our power plugs do not perfectly fit or are worn out. We want to replace them with better ones.

This might already be solved with #4

• Testing with existing print (Made in Bangkok)
• Test other 3D printing materials/designs (e.g., Carbon fiber reinforced) → kindly ask German
• Sheet metal?
• Remove head pan joint? (see #36)

diagonal like darwin,

check rules first
