+## chassis
12
+
13
+- [[rocker-bogie-suspension-dat]]
14
+
15
+The **Curiosity rover** uses a special mobility system based on the famous NASA **“Rocker–Bogie Suspension”** design.
16
+Its chassis gives it several important advantages on rough Martian terrain:
17
+
18
+---
19
+
20
+### 1. **High Stability Over Rough Terrain**
21
+- The rocker–bogie system keeps all wheels in contact with the ground.
22
+- The rover stays stable even when wheels climb over large rocks or dips.
23
+- It greatly reduces the chance of tipping over.
24
+
25
+---
26
+
27
+### 2. **Excellent Obstacle-Crossing Ability**
28
+- Curiosity can climb over rocks as tall as **65 cm** (about twice the wheel diameter).
29
+- It can also traverse slopes up to **30 degrees**.
30
+- Ideal for Mars’ uneven, rocky environment.
31
+
32
+---
33
+
34
+### 3. **Low Shock / Smooth Motion**
35
+- The suspension has **no springs**, so there is no bouncing.
36
+- Reduces shock to instruments (cameras, spectrometers, drills).
37
+- Increases measurement accuracy and protects hardware.
38
+
39
+---
40
+
41
+### 4. **High Durability and Reliability**
42
+- Few moving parts → less chance of mechanical failure.
43
+- Works in extremely cold Martian temperatures.
44
+- Designed for long missions (original goal: 2 years, now over 10+ years).
45
+
46
+---
47
+
48
+### 5. **Six-Wheel Drive System**
49
+- All six wheels have independent motors.
50
+- If one wheel is damaged, the rover can still move.
51
+- Provides very strong traction on sand, soil, and rock.
52
+
53
+---
54
+
55
+### 6. **Articulated Steering (Front & Rear Wheels)**
56
+- Front and rear wheels can steer.
57
+- Allows “tank-like” pivot turns in place.
58
+- Reduces turning radius and improves maneuverability.
59
+
60
+---
61
+
62
+### 7. **High Ground Clearance**
63
+- Tall chassis avoids getting stuck on rocks or ridges.
64
+- Keeps sensitive scientific instruments safe.
65
+
66
+---
67
+
68
+### 8. **Central Body (Chassis) Protects Instruments**
69
+- Houses power system (RTG), computers, and sensors.
70
+- Provides insulation against radiation and extreme temperatures.
71
+- Serves as a strong frame for the robotic arm and mast.
72
+
73
+---
74
+
75
+### Summary
76
+Curiosity’s chassis is optimized for:
77
+- stability
78
+- durability
79
+- obstacle handling
80
+- accurate scientific operation

3
+
4
+A Li-ion cell showing **0 V** usually means something seriously wrong.
5
+Two main causes:
6
+
7
+---
8
+
9
+## 1. **Protection Circuit Tripped** (Only for “protected 18650”)
10
+Some 18650 cells include a tiny PCB at the bottom.
11
+If the cell is over-discharged, the protection board **disconnects** the output → terminal voltage reads nearly **0 V**.
12
+
13
+- Internal cell voltage is usually still **1–2 V**, not truly 0 V.
14
+- Only applies if your cell is a **protected** 18650.
15
+
16
+---
17
+
18
+## 2. **Cell Is Internally Damaged** (Most common)
19
+A fully unprotected or old 18650 can reach 0 V if:
20
+
21
+- Severe over-discharge
22
+- Internal chemical breakdown
23
+- Internal short circuit
24
+- Copper plating inside
25
+- Safety vent (pressure valve) triggered
26
+
27
+If the safety vent opens, the cell is **permanently unsafe**.
28
+
29
+**True 0 V = the cell is dead.**
30
+
31
+---
32
+
33
+# ⚠️ Can You “Fix” a 0 V 18650?
34
+**No. Not safely.**
35
+Trying to recharge a 0 V Li-ion can cause:
36
+
37
+- Fire
38
+- Venting hot gas
39
+- Explosion
40
+- Thermal runaway
41
+
42
+Even trained engineers only attempt recovery in fireproof labs.
43
+
44
+**For home use:
45
+0 V = NOT repairable.**
46
+
47
+---
48
+
49
+# ✔️ What You Should Do
50
+- Do **NOT** charge it.
51
+- Do **NOT** heat, hammer, or puncture it.
52
+- Recycle it at an **e-waste / battery recycling point**.
53
+
54
+This is the only safe option.
